Mineral insulation thermocouples, commonly referred to as MgO (magnesium oxide) thermocouples, are used in many laboratory processes and applications. They are available in J, K, T, E, N thermocouples and a wide range of different sheath diameters and materials. Their nature is flexible and bendable, and their relatively high temperatures make MI thermocouples suitable for many measurement applications. Temperature makes it a popular option.

Head-to-head thermocouple means that the terminal connections are placed inside an aluminum box on top of the thermocouple and the head is selected according to the environmental conditions. Heads are divided into two general parts: IP67 head Which has a degree of protection against dust and condensate, which is used in most cases, and later explosion-proof heads, called Explosion Proof, which are widely used in the oil industry.

Wired thermocouples with junction boxes are used in situations where the distance between the measuring point and where the technician can be present is large. This distance establishes the connection with a cable of the same type of thermocouple and signals inside the box in Located farther away from the thermocouple is connected.
