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.

Nipple thermocouple means that the threaded head and connection are separated by a metal interface with a threaded end. In cases where the temperature measuring point is too hot and causes damage to the head, a nipple thermocouple is used. There are two general types, the first with the ability to replace the sensor, which is suitable for places where the sensor is placed inside the thermowell and the sensor sheath does not weld to the nipple, and the second without this feature means that the sheath is welded to the nipple tube due to sealing. Welding allows the sensor to be directly exposed to the fluid. Nipple Union Thermocouple The nipple means that a union or tube bead is placed between two nipples for places where the sensor was difficult to install and the possibility of wrenching in It is not possible to lower it.
