  • Application

    Characterized by simplicity and compact construction, the Easytemp TMR35 is available with a range of hygienic process connections. It offers good accuracy and response times and has been specifically designed for hygienic applications with 3-A certification.


    The compact thermometer consists of a Pt100 class A sensor, (optional) transducer and housing with hygienic process connection. 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.
