MDTM89 Dual Temperature Swichgage®

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.

Features:

• Monitor inputs from two thermocouples
• Adjustable switch trip point for each input
• FET or SCR output
• Power from CD ignition or 120 VAC or 12/24 VDC
• Types “J” or “K” ungrounded thermocouples
• Digital readings in Fahrenheit or Celsius
