  • Application

    The Easytemp TSM487 temperature compact thermometer is widely used in many light or medium duty applications either in vessels or in pipes with low pressures and no extreme temperatures. 

    Function

    The fiber isolated inset sits in a protecting tube with process connection G ½" cable. The head transmitter (DIN 43729 form B) is made of aluminium. The integrated electronics convert the resistance value in a linearly temperature 4 to 20 mA signal. 

    Installation instructions

    Pipe installation:

     

    a) At elbows, against the flow

    b) In smaller pipes, leant against the flow

    c) Perpendicular to the flow
