In temperature measurement technique, the use of Mantel – mineral insulated thermocouples and resistance thermometers is growing more and more in all industrial processes.

Their difference in use compared to thermocouples and resistance thermometers of classical structure is in the following:

– there is no contamination and oxidation of the hot end of the thermocouple, because it is in highly compressed magnesium oxide, without the presence of oxygen,
– connection of the sensor and the lines is in highly compressed magnesium oxide, without the presence of oxygen,
– faster response,
– great resistance to vibrations,,
– higher reliability in operation,
– longer service life.

Technical characteristics

Outer diameter of the mantle ranges from 0.15 to 8.00 mm.

Thermoelectrodes of the thermocouple and resistance thermometer sensor lines are insulated with highly compressed magnesium oxide. They are placed inside a thin-walled tube made of fire-resistant and stainless steel.

Thermoelectrodes of the thermocouple and resistance thermometer sensor lines are insulated from each other and from the sheath.

The ends of thermoelectrodes are welded and form a hot joint, and the sheath is closed at that end with the so-called cap for mantels, which is made of the same material as the mantel sheath.

The hot end is isolated from the mantel sheath, but it can be, upon customer’s request, welded to the sheath – “brought to mass”.

In the mantel resistance thermometer, lines are punctuated for the leads from the sensor, and the sheath is closed at that end with the so-called cap for mantels, which is made of the same material as the mantel sheath.

Use

– in furnaces / drying kilns;
– in gaseous and liquid media (air, gas, water, oil, etc.)
– on external surfaces: containers, pipelines, apparatus and machines,
– in laboratory and experimental devices,
– in environments with high and low pressure, with large currents, etc.
