  • Application

    The iTHERM ModuLine TM121 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

    iTHERM ModuLine TM121 assembly includes a non-replaceable insert in a mineral insulated sheath. The head transmitter is thermally decoupled via an extension neck. The integrated electronics (optional) convert the resistance value in a linear 4 to 20 mA temperature signal.

    Installation examples

    iTHERM ModuLine TM121 thermowell thermometer - Installlation examples

    1 – 2 In pipes with a small cross-section, the sensor tip should reach or extend slightly past the center axis of the pipe (=U).

    3 – 4 Slanted orientation.

     

    The immersion length of the thermometer influences the accuracy. If the immersion length is too small, errors in the measurement are caused by heat conduction via the process connection and the container wall. Therefore, if installing in a pipe the immersion length should be at least half the pipe diameter. Installation at an angle (see 3 and 4) could be another solution. When determining the immersion length or installation depth all the parameters of the thermometer and of the process to be measured must be taken into account (e.g. flow velocity, process pressure). The counterparts for process connections and seals are not supplied with the thermometer and must be ordered separately if needed.
