    Is this temperature sensor not the perfect match for your application?

  • Application

    The iTHERM TM402 in hygienic design measures the temperature in vessels and pipes, e.g. during cleaning and sterilization, in heating/cooling processes. It is specially designed for use in hygienic and aseptic applications in the Food & Beverages and Life Sciences industries.

    Function

    The compact thermometer consists of a thin film platinum resistance temperature sensor (Pt100 class A), a transmitter (optional) and a housing (aluminum or stainless steel), with various process connections. As an option the signal can directly be converted into a 4 to 20 mA signal using a built-in head transmitter.

    Application example
