ThermoExpert Deutschland GmbH | advanced heating products | mineral insulated thermocouple, mineral insulated thermo couple, mineral insulated metal sheathed thermocouple, mineral insulated copper sheathed cable
Mineral insulated thermocouples are used in the industry to measure temperatures at difficult-to-reach places, since they are extremely flexible and allow a high degree of measurement accuracy. High-quality thermocouples also have a long life time. This is an indispensable product with a large variety of applications in industry and research. Some compositions are as a standard design, but most sheathed thermocouples are produced customer-specific in all conceivable designs. The composition of an individual thermocouple is remarkably simple and comprises six parameters.

KNOW HOW

 

A mineral-insulated thermocouple is structured like a modular system. It allows different sort of mineral-insulated thermocouples to be designed, which can be combined with a hot-junction as well as a selection of connections. This produces the following basic variations:
