  • Application

    iTHERM CompactLine TM311 is developed for universal use in hygienic and aseptic applications in the food & beverages and pharmaceutical industries, and for optimum standardization for machine and skid builders.

    Function

    The compact thermometer measures the process temperature with a Pt100 sensor element (class A, 4-wire). An optional built-in transmitter converts the Pt100 input signal. The device with integrated electronics automatically detects the type of communication (IO-Link or 4 to 20 mA).

    Application example

    iTHERM CompactLine TM311 - Application example

    The immersion length of the compact thermometer can considerably influence the accuracy. If the immersion length is too short, measurement errors can occur as a result of heat conduction via the process connection and the vessel wall.
    If installing in a pipe, the immersion length should ideally correspond to half of the pipe diameter.

    Installation possibilities: pipes, tanks or other plant components.
