Modular sheath thermocouples

Probe with connection head made in Germany for measuring with precision temperature measurement up to 1000 degrees

Measuring with precision and sheer endless possibilities.
No idea is too daring, no project is too complicated for us.

Mineral-insulated sheath thermocouples are used in industry for temperature measurement in hard-to-reach places, as they are extremely flexible and enable high measurement accuracy. In addition, mineral insulated thermocouples have a good resistance to mechanical stress as well as vibrations. Especially with small outside diameters they convince by their fast response times. High-quality sheathed thermocouples also have a long service life. An indispensable product with a wide range of applications in industry and research.

Some compositions are available as standard designs, but most sheath thermocouples are custom-made in every conceivable design. The composition of an individual sheath thermocouple is very simple.

Structure of a sheath thermocouple

The design of a sheath thermocouple works like a modular system. Different sheath thermocouples can be designed, each of which can be combined with a measuring point and a selection of connections. This results in the following basic variants:
