  • Application

    The Thermophant T TTR35 is a Desina compliant temperature switch for the monitoring, display and control of process temperatures in hygienic applications.


    A platinum sensor located at the measuring tip changes its resistance value depending on the temperature. This resistance value is recorded electronically. The conversion of the resistance value into a temperature measurement signal is defined by the international standard IEC 751. 

    Application example

    Hygienic Pt100 temperature switch Thermophant T TTR35 - Installation example

    The Thermophant detects the temperature in the vessel and monitors the compliance with limit values.
