  • 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
