Our Weiber muffle furnace are front-loading box-type ovens or kilns for Low Medium and high-temperature applications such as fusing glass,, creating enamel coatings,ceramics and soldering and brazing articles, beside having a lot of laboratory and industrial applications. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is noncombustible and non-volatile (i.e., ash). Weiber offers unique control modules and microprocessor based programmable digital controllers (optional),, which allow RS232 interface and permit the operator to program up to 126 segments, such as ramping, soaking, sintering, and more.

Applications Our furnaces are usually heated to desired temperatures by conduction, convection, or blackbody radiation from electrical resistance heating elements. Therefore there is no combustion involved in the temperature control of the system, which allows for much greater control of temperature uniformity and assures isolation of the material being heated from the byproducts of fuel combustion.

Unique Features Weiber

muffle Furnaces feature ceramic fiber

insulation for fast heat-up and reduced energy consumption. Embedded heating elements on three

MODULES Slots of modules AI-518/518P series instruments have five slots for modules to be installed (D dimension instruments have 3 slots: OUTP, AUX and COMM/AL1; D2 dimension instruments have 2 slots: OUTP and COMM/AUX). By installing different modules, the controller can meet the requirements of different functions and output types. •

Multiple function Input / Output (MIO)

Can input signal from 2-wire transmitter or 4-20mA signal by installing I4 (current input) module and I4 module can provide 24VDC to transmitter. If a I2 (onoff signal input) module is installed, the instrument can switch between set points SV1 and SV2 by an external switch. Cooperating with OUTP and installing a K3 module can realize three-phase thyristor zero cross triggering output.

Main output (OUTP)

Commonly used as control output such as on-off control, standard PID control, and AI PID control. It can be used as retransmission output of process value (PV) or set point (SV). Installing L1 or L4 modular can realize relay contact output; installing X3 or X5 module can realize 0-20mA/4-20mA/0-10mA linear current output; installing G module can realize SSR voltage output; installing W1 or W2 module can implement TRIAC no contact switch output.

•

Alarm (ALM)

Commonly used as alarm output. Support 1 normally open + normally close relay output (AL1) by installing L1 or L2 module or 2 normally open relay outputs (AL1+AL2) by installing L5 module.

Auxiliary output (AUX)

In a heating/refrigerating dual output system, module X3, X5, L1, L4, G, W1, W2 can be installed for the second control output. It can also output alarm by installing L1, L2 or L5 module, or be used for communicating with computer by installing R module (RS232C interface).

•

Communication Interface (COMM)

Module S or S4 can be installed in for communicating with computer (RS485 communication interface), and it can also be used as power supply for external sensor when equipped with a voltage output module.

Heating Elements Silicon carbide (SiC) electric heating elements for element temperatures up to 1525°C , available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment.

Weiber SiC heating elements are capable of high power output, and may be mounted either vertically or horizontally. Because the element material remains rigid even at the maximum operating temperatures, no special supports are required, which simplifies the design of the equipment.
