The Murphy 0-1999F Dual Temperature Swichgage 100-350 VDC MDTM89-F-A-J is an electronic, dual-temperature 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 includes: Compressor suction/discharge temperature • Engine/compressor jacket water temperature • Engine exhaust temperature • Compressor cylinder temperature • After cooler temperature • Bearing temperature.
