Description

The sensor consists of an exchangeable measuring insert, outer ceramic protective tube and aluminum connection head where mounting a temperature transmitter with 4-20 mA/HART® or Profibus®PA output signal is possible.

The measuring insert that is used makes an exchangeable part of the sensor which means that only the insert and not the whole sensor has to be disassembled in case of damage or for the purpose of periodical checking. Costs of the maintenance are reduced then.

Thermocouple length, diameter of ceramic tube, connection head as well as type and number of sensors, accuracy and method of connection can be selected individually for the respective application.

Temperature transmitter ( Option )


Transmitter is mounted inside the connection head of the sensor: directly on measuring inset or in the high cap of head.



The second method is advantageous as it allows changing standard measuring inset quickly without a need to disassemble the transmitter; it means reduction of time and costs of maintenance of the sensor and protecting wires against any damage possible. Mounting of two transmitters inside the connection head available upon request.
