FW Murphy, 10703051, MDTM89 Series Dual Temperature Gage, Fahrenheit Calibration, from 400 deg - 2000 deg F
It is an electronic, dualtemperature monitor. It monitors two thermocouples, displays the temperature of the thermocouple selected and has adjustable trip points for each input. A toggle switch provides for selection of the thermocouple to be displayed and/or the temperature trip point to be checked/adjusted. If either trip point is reached, the associated output turns on and can be used as a control signal or to initiate alarms and/or shutdown. A Push to Read button, located below the selector switch, allows the operator to check the trip point and to see its value as adjustments are made. Two potentiometers, one on each side of the thermocouple selector switch, are provided for field adjustment of the trip points.
Applications include the following:
- Compressor suction/discharge temperature
- Engine/compressor jacket water temperature
- Engine exhaust temperature
- Compressor cylinder temperature
- After cooler temperature
- Bearing temperature
