Temperature gage MDTM89

manualswitchdigital

Monitor inputs from two thermocouples Adjustable switch trip point for each input FET output Power from CD ignition or 120 VAC or 12/24 VDC Types “J” or “K” ungrounded thermocouples Digital readings in Fahrenheit or Celsius FW Murphy’s model MDTM89 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 There are two basic models. One of the models is powered by capacitor discharge ignition and an FET output. One model operates from 12- or 24-VDC and has an FET output. Standard display is in degrees Fahrenheit; degrees Celsius is optional. Applications include the following: Compressor suction/discharge temperature Engine/compressor jacket water temperature Engine exhaust temperature Compressor cylinder temperature After cooler temperature Bearing temperature Thermocouple Type Either J or K type UNGROUNDED THERMOCOUPLE is accepted. Specify type in part number for each MDTM89 unit (see How to Order). Order thermocouples as a separate item.
