DP & Flow Transmitter MICRO-BAR DIFFERENTIAL PRESSURE/FLOW TRANSMITTER Micro-Bar electronic transmitter incorporates a capacitance based differential pressure cell for sensitive measurement on Air or other dry gases. Designed for gas flow measurement applications on extraction or ventilation systems, the micro based electronics uses calibration formulae required for FloBar Averaging Pitot tubes, Orifice Plates or other standard DP based sensors. Simply installed adjacent to the flow line, standard pressure impulse tubing links the sensor directly to the Micro-Bar unit. Flow rate,flow units and alarm status are displayed on the two line LCD: external signal transmission is via the 4-20mA loop power,with separate alarm relay and totaliser pulse.

FEATURES •

DP measurement for gases

•

High sensitivity and linearisation for Pitot tube flow measurement

•

Digital flowrate display in Engineering units

•

±0.5% accuracy

•

Flow totaliser pulse output

•

High and low flow alarms

•

Site programmable outputs

With simple adjustment over a 5:1 full scale pressure range available to the operator on site, the Micro-Bar suits varying process conditions or output scaling requirements. The micro based electronics simplifies site setup procedures, allowing adjustment of alarm output set points, totalisation pulse rate, averaging time and zero checking. Micro-Bar is applicable to measuring pressure differentials on operating theatres, clean rooms or glove boxes, to monitor system performance and provide alarms. On process monitoring, Micro-Bar is used for air filter blockage monitoring and burner control on furnaces. For these duties, the display shows the pressure drop directly.

MICRO-BAR APPLICATIONS

DIMENSIONS 15

FLOW MEASUREMENT Pressure ports are connected to a Platon Flobar Averaging Pitot tube or orifice plate via 4mm OD nylon impulse pipes. Using the calibration sheet supplied with the Flo-Bar, the Micro-Bar full scale pressure is ranged to the appropriate value for site conditions. Units are selected from the look up table and the square root extraction mode used to give using the Micro-Bar press buttons. Remote transmission is via the 4-20mA loop, wired via a recorder and display to a DC power source.

Simple impulse tube pressure connections can be made to the Micro-Bar unit to monitor DP across a filter, to detect blockage, or to a pressurised clean room, to monitor the maintenance of the required DP and alarm on hazardous conditions. Micro-Bar units provide the analogue output for recording purposes and the alarm output to signal the potential hazard: two separate alarm levels are available.

DP Gauge with Alarms PHOTOHELIC ® DIFFERENTIAL PRESSURE GAUGES WITH ALARMS

SPECIFICATION DP Ranges Accuracy Media Housing

Using solid state technology, the Series 3000MR Photohelic® switch/gauges combine the functions of a precise highly repeatable differential pressure switch with a large easy-to-read analogue pressure gauge employing the durable timeproven Magnehelic® design. Switch setting is easy to adjust with large external knobs on the gauge face. Gauge reading is unaffected by switch operation, it will indicate accurately even if power is interrupted. Solid state design now results in greatly reduced size and weight. Units can be flush mounted in 4 13/16" (122 mm) hole or surface mounted with hardware supplied. 3000MR models employ versatile electromechanical relays with gold over silver contacts that are ideal for dry circuits. All models provide both low and high limit control and include 18-inch (45 cm) cable assemblies for electrical connections. Gauge accuracy is ±2%of full scale and switch repeatability is ±1%. Switch deadband is one pointer width; less than 1% of full scale. Compatible with air and other non-combustible non-corrosive gases they can be used in systems with pressures to 25 psig (1.725 bar). Optional construction is available for use to either 35 psig (2.42 bar) or 80 psig (5.51 bar).

P193 Pressure Capsule The P193 pressure sensor is a low cost pressure capsule available in standard ranges from 100mbar to 600 bar. All ranges are available in gauge or absolute format. It is ideal for continuous use in applications where the pressure medium is wet and corrosive and long term stability is of prime importance.

DESCRIPTION The type P193 pressure sensor is manufactured from high purity alumina ceramic. This material possesses superb chemical and abrasion resistance, making it unrivalled for use with virtually any pressure medium. The diaphragm of the sensing element has a fouractive-arm strain gauge bridge fused to its inner face. This direct fusion ensures excellent long term stability and repeatability, which, coupled with the matched bridge network, provides excellent linear thermal characteristics.
