Process Control Equipment

Product Details:

Our process indicator and controller is available in 4150XX series which has ability to display and control variety of physical parameters. These process indicator are powerful, highly flexible and can accept inputs from variety of sensors like all types of thermocouples, RTDs, pressure transducers, mV, mA, LVDTs, etc. The input can be either directly from the sensor or 4-20 mA transmitter, 3 ½ or 4 ½ digit, 0.5" Red 7 segment LED display and keyboard. It also has Thumbwheel switches and potentiometer for set points and programmable decimal points. It has the ability to program two relays to operate for the (parameter under measurement) > setpoint or < setpoint.
