Thermocouple assemblies with ceramic protection tube and mineral-insulated measuring insert

Straight line thermocouple assemblies with ceramic protection tube and mineral-insulated measuring inserts (15-TKM) are used for common temperature measurement up to 1200°C, mainly in gaseous media.

For sensors of this product line, mainly base metal thermocouples are employed, combining the advantages of mineral-insulated measuring inserts on one hand, and the advantages of technical ceramics on the other hand.

The individual properties of the most common ceramic types can be found on page 73, in the chapter “Technical information”.

Additionally and in contrast to thermocouples, mineral-insulated measuring inserts are easily exchangeable, they are resilient to temperature changes, vibration and impact resistant. In conse- quence of the compact and slender configuration of the mineral- insulated measuring inserts, enough space usually remains to allow for the insertion of an additional mineral insulated  thermocouple for measurement verification if necessary.

During measurement and control processes, often high opera- tional wear occurs due to corrosion and abrasion, which even high grade metal protection tubes are not able to withstand. In these scenarios, thermal sensors with Protection tubes made of heat- resistant, technical ceramics allow for increased holding time in many instances.

Thermoelectric voltages and tolerances of our mineral-insulated measuring inserts are according to DIN EN 60584, class 1.
