Mineral insulated thermocouples, also known as sheathed thermocouples, consist of a metal sheathed cable with internal thermocouple wires insulated from each other and the outer sheath with magnesium oxide (MgO) powder. This gives the sensor high vibration resistance, flexibility as well as temperature resistance and good electrical insulation.
These sensors are designed to directly measure the temperature in hard-to-reach places, as well as in all places where it is necessary to use flexible sensors of small diameters, high resistance to vibration and shock, and with a long time short response to temperature changes.
Due to the tight pressing of the insulating layer (MgO) and the proper structure of the inner wires and jacket, the sensors can be bent with a minimum bend radius of three times the outer diameter of the jacket.
