  • Application

    The Easytemp TSM187 compact thermometer range covers a wide variety of market needs. Typical applications can be found in the chemical and pharmaceutical industry, pulp and paper, waste water and food industry. It is widely used in vessels and pipes where a reasonable response time is required. 

    Function

    TSM187 assembly includes a replaceable inset, in a mineral insulated sheath with a G½" process connection. The head transmitter (DIN 43729 Form B) is thermal decoupled via a extension neck. The integrated electronics convert the resistance value in a linearly temperature 4 to 20 mA signal.
