Temperature transmitter application

Temperature transmitter with standard 4 to 20mA, 0 to 10V output signals and with standard communication protocols can be mounted in the connection head. Transmitter installation is carried out directly on the measuring insert (in place of a terminal block) or in the high cover connection head (solution used to enable installation of two transmitters).

Local display application

The temperature sensor can be equipped with the connection head enabling the local LED display installation. The local display operates in current loop 4 to 20mA. This version makes the local temperature reading and transmission of the analogue signal possible.

ATEX design

For use in hazardous areas adequate sensor constructions are available:

  • intrinsically safe Exi
  • flameproof Exd

These designs possess EC-Type Examination Certificate in compliance with 94/9/EC(ATEX) directive.

Non-standard design

Immersion length, process connection, shape and material of the thermowell, connection head type and measuring insert parameters can be customized per client request
