    The ISE/Gentan model GT439 Digital Pressure/Temperature indicator/power supply is designed for use with any four leg, 350 ohm Wheatstone bridge pressure transducer. Zero and span can be easily adjusted without removing the module. Shunt calibration is a standard feature.


    The large 4½ digit, 1/3 inch LED pressure display is easy to read, even from a distance. Custom face plates are not required for specific scales because every unit can be set for 12 different ranges.  Other markings can be easily added for engineering units. The last digit is a fixed zero.

    A three digit LED temperature display is also included.


    Two alarms can be selected for above or below setpoint control. Relays provide N.O. (normally open) and N.C. (normally closed) contacts for maximum flexibility. Adjustments are made through pots on the faceplate.


    Provides a choice of recorder outputs, damping constant, transducer sensitivities, input power, shunt-resistor calibrations, peak-hold, and reset options.


Can be set to operate with Gentran or other styles of transducers.


    The easy-to-mount aluminum housing fits a 1/4 DIN cutout. Slide-type metal brackets hold the case firmly in place and can be installed quickly. The electronic module can be easily removed for option selection or service
