Application
The Easytemp TMR31 is a compact cost-effective thermometer that has been designed for use in all general applications across the process industries.
Function
The compact thermometer consists of a Pt100 class A sensor, (optional) transducer and housing with process connection. The TMR31 is available without a process connection so that it can be combined with a TW251 thermowell (with compression fitting) for insertion into a process. The built-in electronics can be programmed using a PC and TXU10-BA configuration kit to convert the Pt100 input signal into a temperature linear 4 to 20 mA signal.
Installation instructions
Pipe installation
a) At angle sections, against the direction of flow
b) In smaller pipes, turned against the direction of flow
c) Perpendicular to the direction of flow
