The measuring inserts per DIN 43735 for resistance thermometers described here are designed for installation in a protective fitting. Operation without a thermowell is only advisable in special cases. The measuring insert is manufactured from bendable, mineral-insulated sheathed cable. The sensor is located in the tip of the measuring insert. The measuring inserts are delivered with loading springs to ensure a good contact to the thermowell floor. Apart from the DIN versions, customer specific versions are available, for example:

  • other measuring insert lengths (also intermediate lengths)
  • with mounted sleeve to suit inner diameter of the thermowell
  • without terminal block
  • with transmitter


Type and number of sensors, accuracy and method of connection can each be selected to suit the respective application.

A large number of different explosion-protected approvals are available for the TR10-A.

The range of applications is completed by designs without terminal block for direct transmitter installation. Optionally, analogue or digital transmitters from the WIKA range can be installed.
