Thermocouples without a thermowell are especially suitable for applications which have metallic sensor tips mounted directly into the drilling holes, e.g. of machine parts or in the process, thus, for all applications without chemically aggressive media and abrasion.

For mounting into a thermowell provide a spring-loaded compression fitting becaus only the fitting can press on the sensor tip to the bottom of the thermowell, without a - potentially critical - application of force onto the sensor tip.

Mounting is usually carried out directly in the process. Fastening elements such as threads, union nuts etc. can be used optionally.

The flexible sensor part is a mineral insulated cable (sheathed cable). It conists of a insulated and pressed into a highly compressed ceramic mass and is, therefore, suitable for use with higher temperatures.
