  • * Output signal: TC or 4..20 mA (option)


Description

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

Insertion length, sheath diameter, connection head as well as type and number of sensors and accuracy 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.
