The measuring inserts per DIN 43735 for resistance thermometers described here are designed for installation in a protective fitting. Operation without thermowell is only recommended in certain applications. The measuring insert is made of a bendable mineral-insulated sheathed cable. The thermocouple is located at the tip of the measuring insert. The measuring inserts are delivered with pressure springs to ensure that the measuring inserts are pressed down to the thermowell bottom.

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, and accuracy can each be selected to suit the respective application.

A large number of different explosion protection approvals are availabe for the TC10-A.

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