Sheath thermocouple with flange

Typical application examples for mineral-insulated thermocouples

Sheathed thermocouples, also known as sheathed thermocouples, are used in various industries and applications where precise temperature measurements are required. This type of thermocouple consists of two different metallic conductors that are connected together at one end and open at their other end. The open ends are placed at the location where the temperature is to be measured. ThermoExpert° Deutschland GmbH, with its managing directors Heiko Gevert and Andreas Helf, has been a partner of all these industries and of research for many years. The range of applications for thermocouples is almost unlimited - and so is the wealth of ideas for getting customers where they want to go.

The hurdles were both for the new colleague, whose degree in metrology was not recognized by German authorities, and for us, because we also had to deal with several piles of small-print paper as an employer.

At the end of the day, however, we have gained a valuable, committed new employee for our international team. We tend to see different cultures as an enrichment, and as an employer we also make it possible to live them.
