Temperature Product Catalogue

Temperature - an overview The Rototherm / Thermocouple range of temperature assemblies has been deisgned for all industrial applications and is manufactured in strict accordance with the companies ISO 9001:2000 Quality System. The range includes probes suitable for direct insertion into processes without protective thermowells and full assembles complete with screwed or flanged thermowells and connection heads.

Connection Heads (pages 4 - 7)

Our comprehensive range of connection heads provides the best environmental protection for the electrical terminals on terminal blocks or temperature transmitters fitted to resistance thermometers or thermocouple inserts.

Temperature Transmitters (pages 8 - 23)

Temperature transmitters are used to convert the primary sensing signal, usually a resistance change for RTD sensors or EMF for thermocouples, into a standard current signal of 4-20mA. We offer a comprehensive range of temperature transmitters suitable for thermocouples or platinum resistance thermometers (RTD), these transmitters may be either head or rack mounted. Temperature ranges may be factory set or user adjusted. (Programmable, intrinsically safe, Hart速, Profibus速 and Foundation Fieldbus速 communication versions are available).

Mineral Insulated Thermocouples (pages 28 - 31)

A Thermocouple consists of two electrical conductors of dissimilar material connected at one end (the hot junction), the two free ends are connected to the measuring instrument via a reference junction (the cold junction). The connection of these two materials provides an electromotive force (emf).

Mineral Insulated Resistance Thermometers (pages 32 - 35)

A Resistance Thermometer is a temperature sensor constructed from resistance wire wound into an element. It is used to measure temperature by means of a change in the electrical resistance with a rise or fall in temperature. The most popular wire used in Resistance Thermometers is platinum, although nickel or copper can also be used.

Lagging Extensions (pages 36 - 37)

Lagging extensions are available in a wide range of lengths, sizes and fittings. Materials include Carbon Steel and Stainless Steel. They allow the connection head to be positioned away from the heat source, or through insulating lagging. Nipple/Union/Nipple and Breakaway couplings allow rapid disconnection for testing, and orientation.

Thermowells (pages 38 - 46)

Thermowells are used extensively in the power, process, pharmaceutical and petrochemical industries. They are used to protect temperature indicators and sensors from process media and to enable servicing or replacement of sensors without the need to shut down plant. Our thermowells are precision made to the highest standards of finish in our modern well equipped machine shop and are manufactured to Rototherm,s high quality standards approved to BS EN ISO 9001. Thermowells are available fabricated from tube or drilled from barstock or forgings, full material certification, including original mill and suppliers materials certificates can be provided. If required NACE standard MR-01-75 requirements can be met. Our custom-design ability puts us ahead of the competition for providing thermowells. As part of an assembly or as a replacement, we can provide thermowells of any size, material and specification. As part of our solution we can also offer stress and frequency calculations to ensure you have the correct design for the job.

Loop Drive Capability

DIN Rail Mounted Version

The TR48 temperature transmitter is also available in a DIN rail mounted version. Manufactured to the same high specification with easily adjustable zero and span potentiometers, this model is ideal when larger numbers are required to be rack mounted.

Wiring Details TR48TC Thermocouple Input

TR48SW Slidewire input The slidewire input version of the TR48 produces a linear output proportional to the position of the wiper of a slidewire or potentiometer. This provides a convenient way of remotely indicating or controlling the position of any motorised actuator fitted with a re-transmission potentiometer.

TR48R Platinum Resistance Input

TR48RD Differential Input

Differential transmitters produce an output proportional to the difference between two precision Platinum Resistance Thermometers. A typical application might be to monitor the efficiency of a piece of plant by detecting the heat loss or gain between input and output. In such applications it is often necessary to measure very small differences. Using a differential transmitter with a span of 20ºC, a resolution of 0.01ºC can easily be achieved using only a low cost digital panel meter.

Configurable with Windows® PC without sensor simulation Analogue signal processing, ideal for multiplex systems Quick response <1 ms to 90% Sensor burnout signalling according to NAMUR NE 43 Electromagnetic compatibility according to NAMUR NE 21 Measuring span from 20 K Compact design

General Description Temperature transmitter for Pt100 in 2 or 3 wire connection with 4...20mA analogue output (loop powered 2 wire technique) The TR24 temperature transmitter combines the known quick response of an analogue transmitter with the flexibility of configuration by means of a Windows PC. The quick stabilisation of the output current after excitation voltage has been applied enables the use of this transmitter in multiplex systems. Setting of the measuring range, type of sensor and sensor burnout behavior takes only a matter of seconds thanks to the easy to use Windows configuration software. Time consuming adjustments and sensor simulation are not required for this transmitter.

Model TR24 Temperature Transmitter

Due to its flexibility and reliability the TR24 temperature transmitter is suited for a wide range of applications in the machine industry and plant construction. As a result of its extremely compact design this TR24 temperature transmitter can be fitted into any DIN connection head of form B. The transmitters are delivered with a basic configuration. Alternatively, upon request, transmitters can be delivered with a customized configuration within the given limits.

The TR24 can be remotely configured from the control room via the current loop. Possible measuring errors which might for example, result from poor thermometer position, can be compensated by means of the function ‘sensor correction’. Write protection and an increased ambient temperatures range complete the spectrum of features offered by the

Loop powered Less than 1V required from loop ATEX approved for us in IS loops IP68 enclosure available Field programmable Wide range of Zero offsets RFI protected 12.5mm high display Operating temperature -10 to +70ºC Low cost

General Description Model DLI1 is a loop powered digital indicator, which can be connected in series with any 4-20mA current loop and will display the current flowing in meaningful engineering units. The large 3 ½ digit display is easy to read and the whole device introduces a volt drop of less than 1V at full scale, which means it can be used where several other devices are already in the loop.

Model DLI1 Loop Powered Indicator

Dimensions

The Zero and span are independently adjustable so the indicator can be can be calibrated to display any range within the +/-1999 range, large positive and negative zero offsets are easily accommodated.

Housings The indicator can be supplied in an EEx de approved, IP68 enclosure in a variety of materials to suit the needs of the environment in which it is installed. Extended versions allow a transmitter and indicator to be conveniently mounted as a single unit.

Connection Diagram

Temperature Transmitters

Installation / Safety Non-Enclosed Unit Certificate No: BAS00ATEX1161X

The enclosure can also contain any of the “ATEX” certified transmitters listed in BASEEFA approved document.

To comply with the requirements of Intrinsic Safety, the “Component Certified” version of model DLI 1 MUST be housed in an enclosure providing a minimum degree of protection of IP20. When an end user wishes to house the unit in any enclosure other than the H70 below, the new assembly MUST be submitted to the “Health & Safety Executive” for re-certification.

“O Ring” seals must be carefully examined after opening to ensure that the IP68 protection is maintained. Damaged seals MUST be replaced.

The current loop MUST be protected by a Certified “Zener Barrier” or “Isolating IS Interface Unit”, with the following maximum output parameters:

Io = 200mA, Po = 0.85W, Uo = 28V.

Non-metallic enclosures must have a surface resistance of less than 1G Ohm, light alloy or zirconium enclosures must be protected from impact or friction when installed. The housing chosen must be made from materials capable of resisting any anticipated extremes of temperature, and shall not be corroded or prematurely aged by the atmospheric conditions it could reasonably be expected to encounter in service. The complete electrical circuit in the hazardous area MUST be capable of withstanding an AC test voltage of 500V RMS to earth or frame of the apparatus. The capacitance and either the inductance, or the inductance to resistance (L/R) ratio of the cables in the hazardous area MUST NOT exceed the parameters specified in the schedule of the chosen safety barrier certificate, and/ or system certificate. Installation MUST comply with the requirements specified in BSEN 60079-14:2003. Where there is a possibility of attack by aggressive substances it must be protected by a suitable enclosure, capable of protecting it from the environment and the effects of impact, thermal or mechanical stress. DLI 1 units must not be fitted in locations where the ambient temperature could be expected to exceed 70ºC (50ºC for enclosed unit). This equipment is designed and manufactured to protect against other hazards as defined in paragraph 1.2.7 of Annex II of the ATEX Directive 94/9/EC. Enclosed Unit Certificate No: BAS00 ATEX 1160X The “Enclosed” version is fitted inside the model “H70” explosion proof enclosure, which is specifically designed for this purpose. Providing protection to IP68, the housing is available in Stainless Steel, Cast Iron or Aluminium. The enclosure is fitted with a window to allow viewing of the display. The explosion proof enclosure DOES NOT mean that it can be used without a suitable IS barrier, except where the entire installation is certified EExde.

H70 Connection Head

Operation The indicator is designed to connect in series with a 420mA current loop, drawing its power from the loop, (Voltage drop only 1V), and converting the current flowing into meaningful engineering units. Connection is by a pair of terminals mounted on the rear of the device, the 4-20mA loop should be broken and the indicator connected in series, taking care to observe correct polarity. The indicator is protected against reversed connections, but no reading will be displayed if incorrect. Connecting directly across a 24V supply without a transmitter or similar device to regulate the loop current will result in a blown fuse, or damage to either the power supply or the safety barrier. Model DLI 1 can easily be ranged to display virtually any engineering units by a combination of the “Zero Offset” DIP switches mounted on the rear PCB, and a pair of coarse and fine “Span Adjustment” potentiometers accessible from the front, above the display. The decimal point can be activated by means of another DIP switch on the rear PCB.

Range Setting Instructions

Certification Details

Zero Offset

Enclosed Unit

The vast majority of ranges will begin at Zero, the standard indicator is supplied with switches 3 & 7 closed, the setting for Zero offset. Once Zero has been set, using the “Z” potentiometer, it will NOT change regardless of the full scale selected.

Non-Enclosed Unit

This default switch combination also allows offsets of approximately 500 to +250 counts (-50.0 or 500 to +25.0 or +250) For larger positive or negative offsets choose a suitable switch combination from the table below. Offset

+1000 to +2000

+250 to +1000

-500 to +250 -1300 to -500

When the enclosure also contains an Intrinsically safe temperature transmitter, a label must be fitted to the outside detailing the model and certification numbers of the transmitter. A list of permissible transmitters and their certification details contained in BASEEFA approved document.

Transmitter Labelling

Span Adjustment Span is set by adjusting a combination of 2 potentiometers, first adjust the “C” pot until close to the required full scale reading, then fine tune with the “F”, fine adjustment pot.

Offset Ranges The method for setting offset ranges is as follows, FIRST set the span required, e.g., for a range of +100 to +500 set a range of 0-400, THEN offset the bottom end by +100, no further adjustment will be required.

Decimal Point If required, the decimal point can be activated by switching either of the DIP switches labelled “DP” at the bottom of the rear circuit board.

Maintenance Model DLI 1 is maintenance free; the electronics are fully encapsulated and cannot be disassembled. Cleaning should ONLY be restricted to wiping with a damp cloth, or approved anti-static cleaner to avoid the danger of ignition due to electrostatic charges.

High Temperature RTDs

Fittings

At temperatures above 500ºC, the platinum wires used in the construction of RTD elements are susceptible to ‘poisoning’ from a variety of sources. The result is rapid drifting of the reading, normally upwards. The most common causes are:-

A wide range of termination glands and adjustable compression fittings are available to suit RTDs of all diameters.

The Sheath Material - iron vapour contamination effectively rules out the use of stainless steels and most nickel alloys. Pure nickel is the preferred material. Oil and Grease - traces of oil left inside the protecting tube, or on the element itself, give off poisonous gases at high temperature. Absolute cleanliness is essential in RTD production.

Wiring Configurations

2-Wire Connection

4-Wire Connection

This method allows NO compensation for lead resistance, which is effectively added to the thermometer resistance.

Must be used when the highest accuracy is needed, particularly where lead runs are long, providing almost total rejection of lead resistance and temperature effects.

Only suitable for low accuracy applications such as domestic appliances, motor vehicles or where lead lengths are very short. Typically leads made from 7/0.2mm copper will add a positive offset of almost 0.5ºC/m.

3-Wire connection

This system is becoming more common as “Intelligent Transmitters” become more popular, as these almost always can use the 4-wire system. Mineral insulated resistance sensors are becoming much more popular in recent years, for their robust, vibration resistant properties, these are normally made using 4 core MI cable, so there is no economic reason not to use all four.

4-Wire Compensated

By far the most common configuration for industrial applications, the 3-wire system allows for effective compensation of lead resistance and also compensates for changes in lead resistance when wires pass through temperature variations (temperature coefficient of resistance of copper is greater than platinum). Remaining errors with this system are mostly due to variations in resistance between the 3 wires.

An unusual system where a “Compensating Loop” of wire, equal in resistance to the thermometer leads is connected to balance their effect. This is normally achieved in a bridge circuit, by connecting the loop in the opposite leg to the sensor. The method can give good results, but is not commonly used with modern instrumentation.

General Description Fabricated Pockets are precision components manufactured to the highest standard from pipe, tube and bar, to serve as protective devices for primary sensing elements of all types. A wide range of possible products are available. Conditions of pressure, temperature, velocity and corrosion resistance govern the size, shape and selection of materials to ensure optimum dependability, response time and accuracy.

Specification Materials We are experienced in the manufacture of fabricated pockets in a wide range of materials, including 304, 310, 316 and 321 Stainless Steels, 446 Cr-Fe, 6% Mo, Haynes Alloys 214, 230, 556 and HR-160, Carbon Steels, Chromium Steels, Duplex and Super Duplex Stainless Steels, Hastelloy B3, C22, C276 and X, Incoloy 800, 825, Inconel 600 and 625, Monel 400 and Titanium.

Fabricated Thermowells

Weld-In Weld in pockets are normally used where process pressure and velocities are too great for flanged and threaded, or where long term inexpensive connections are required. Reduced Tip For applications where a quick response to changes in temperature is required, fabricated pockets may be fitted with a reduced tip. The tip is machined from bar-stock, with a bore suited to the primary element, minimising the amount of free air space around the sensor.

For recommendations on the use of these materials, please refer to page 38. Pocket Size We can fabricate pockets from a wide variety of tube or pipe sizes including 11 mm x 7 mm, ¼” NB, ½” NB, ¾” NB, 1” NB and larger, in a variety of schedules subject to requirements and process conditions. Instrument Connection Instrument connections may be male or female, in API, NPT, BSP or other thread forms. Process Connection Connection to the pipe or vessel may be by means of thread, flange or weld. Threaded Using standard tapered or parallel pipe threads for simplicity and low cost is popular, generally for low pressure applications. Standard threads are NPT, BSP(Pl), BSP(Tr) and API. The thread size is dependent on the application. Standard sizes range from ½” to 2”. Flanged All sizes and pressure ratings are available to DIN, BS, ANSI/ASME and JIS or other standards. Flanged connections are now the petrochemical standard for all applications.

Immersion Length The immersion length should be calculated to ensure that the sensing element has sufficient immersion into the process medium to give accurate measurement. To ensure optimum results and freedom from outside influences, thermowell tip should be located at a point which equates with the lower portion of the centre third of the pipe line. For tanks, the depth of immersion obviously varies considerably but, as a rule of thumb, 300 mm from outer wall will give ideal results. In high velocity applications, wake frequency effects must also be considered. Refer to page 49 for more information. Immersion length is defined as shown.

Standard Thermowells

Surface Finish Thermowells are supplied as standard with a fine machined surface finish. Other finishes may be supplied on request.

The following are the most common fabricated pockets available. Other designs are available to customers’ standards, as the application requires.

Special Coatings We have specialist in-house facilities for coating thermowells to increase corrosion and abrasion resistance. Options include Stellite®, Tungsten Carbide, Tantalum, Zirconium and PTFE. Stub Flange Arrangement When a fabricated pocket is manufactured from exotic materials, for example Inconel®, Monel®, Hastelloy® or Titanium, it is not necessary for the whole flange to be of the same material. For economic reasons, we offer a stub flange typically 3mm thick with a diameter equal to the raised face. This is welded to the Thermowell stem and is supplied fitted with a loose backing flange normally manufactured in 316 stainless steel or carbon steel.

Weld Procedures We employ ASME IX coded welders, experienced in stainless steels, Carbon Steels and exotic materials. Welding procedures, qualification records and welder approval certificates can be supplied on request. Heat Treatment Thermowells may be heat treated to customers’ requirements. The requirements of NACE MR 01-75 can be met. Quality Control / Inspection Our thermowells are manufactured under a strict ISO 9001-2000 quality control system. A wide range of documentation and Non Destructive Testing can be provided on request, including:

Material Certification (EN 10049 3.1b) Certificate of Conformity Hydrostatic Pressure Test Dye Penetrant Inspection Radiography Ultrasonic Bore Concentricity Test Positive Material Identification Intergranular Corrosion Test Hardness Testing

General Description Solid Drilled Thermowells are precision components manufactured to the highest standard from bar or forgings, to serve as protective devices for primary sensing elements of all types. A wide range of possible products are available. Conditions of pressure, temperature and corrosion resistance govern the size, shape and selection of materials to ensure optimum dependability system response and accuracy.

Specification Materials We are experienced in the manufacture of solid drilled thermowells in a wide range of materials, including 304, 310, 316 and 321 Stainless Steels, 446 Cr-Fe, 6% Mo, Haynes Alloys 214, 230, 556 and HR-160, Carbon Steels, Chromium Steels, Duplex and Super Duplex Stainless Steels, Hastelloy B3, C22, C276 and X, Incoloy 800, 825 and MA956, Inconel 600 and 625, Monel 400 and Titanium. Some suggested materials for various temperatures are shown in the chart below.

Solid Drilled Thermowells

Flanged Connection All sizes and pressure ratings are available to DIN, BS, ANSI/ASME and JIS or other standards. Flanged connections are now the petrochemical standard for all applications. Weld-In Connection Weld in thermowells are normally used where process pressure and velocities are too great for flanged and threaded, or where long term inexpensive connections are required. Immersion Profile The profile should take account of fluid flow characteristics, strength of thermowell and immersion length.

For recommendations on the use of these materials, please refer to page 38. Instrument Connection Instrument connections may be male or female, with API, NPT, BSP, or other thread forms. Process Connection Connection to the pipe or vessel may be by means of thread, flange or weld. Threaded Connection Using standard tapered or parallel pipe threads for simplicity and low cost is popular, generally for low pressure applications. Standard threads are NPT, BSP(Pl), BSP(Tr) and API. The thread size is dependent on the application, but ¾” and 1” are common.

Tip Profile Consideration should begiven to tip profiles when designing the thermowell for a specific application . As a rough guide, flat tip should be used for lower pressure applications, where flow characteristics around thermowell are not important. Domed and spherical profiles should be used in medium and high pressure applications respectively where flow characteristics around thermowell are important.

Solid Drilled Thermowells

Bore Selected to suit primary sensing element, ensure ease of removal and minimise the amount of free air space around sensor, thus providing optimum response time. In general the outside diameter and bore of the thermowell should be such that the minimum wall thickness is 3 mm. We operate specialised deep bore gun-drilling machines to ensure the concentricity and finish of the thermowell bore. Immersion Length The immersion length should be calculated to ensure that the sensing element has sufficient immersion into the process medium to give accurate measurement. To ensure optimum results and freedom from outside influences, thermowell tip should be located at a point which equates with the lower portion of the centre third of the pipe line. For tanks, the depth of immersion obviously varies considerably but, as a rule of thumb, 300 mm from outer wall will give ideal results.

Pressure Gauges

The Rototherm/Thermocouple range of Orifice and Restriction Orifice Plates are based on proven technology - suitable for high temperature and pressure applications.

British Rototherm has worked hard to establish itself as a world class manufacturer of pressure gauges.

Orifice Plates are recommended for clean liquids, gases and low velocity steam flows. The range includes Tab Handled Orifice Plates, Restriction Orifice Plates, RTJ Type Orifice Plates, Orifice Carrier Assemblies, Venturi Tubes and Nozzles, Averaging Pitot Tubes and Orifice Flanges. As well as Orifice Plates, Rototherm is able to offer:

Flow Nozzles For measurements where high temperatures and velocities are present, the flow nozzle may provide a better solution than an orifice plate.

Venturi Tubes There are two common types of Venturi tube - the Venturi nozzle, and the classical Venturi. Both feature a convergent inlet section and a divergent outlet section. The major advantage of the Venturi over orifice plates and flow nozzles is in the area of pressure recovery.

Pitot Tubes These practical and effective Differential Pressure primary elements can, in some applications, match Venturi's in terms of performance at a substantial cost advantage, especially for large diameter pipelines.

With the acquisition of the pressure gauge manufacturer Sydney Smith Dennis (SSD) in 1998, Rotothermâ&#x20AC;&#x2122;s range of pressure gauges dramatically increased to include gauges to suit most industrial applications.
