The Murphy 0-1999°F 6-Channel Temperature Scanner and Pyrometer 80-250 VDC Type K TDX6-A-F-K is an advanced design 6-point temperature scanner and pyrometer. It continually scans up to six thermocouples and sequentially displays the thermocouple number and its reading. Each sensor input has a field settable trip point for alarm, shut-down or control. A read/scan selector allows the operator to set and view each trip point. With the selector in the scan mode, a “thermocouple read” push button provides a means to manually toggle through the six channels and to lock in on a specific channel. Normal scanning will resume approximately three seconds after releasing the push button. All trip points are continually armed and active during the scanning process. The TDX6-A-F-K can interface with other Murphy Selectronic Tattletale annunciators and Micro-controllers. It is rated for Class I, Division 2, Group D, hazardous areas. Type K, grounded or ungrounded thermocouples are accommodated. Using grounded thermocouples introduces the risk of odd currents or voltages being imposed on the thermocouple signal which can affect the accuracy of the reading.

Applications: Gas Compressor, Process Temperatures Suction/Discharge Temp., Generators, Engine/Compressor Jacket, Pumps Water Temperature and Engine Exhaust Temperature.
