RRESIOPAK®Mineral Insulated Resistance Thermometer Sensor

RESIOPAK is our trademark for sheathed resistance thermometer sensors.
It consists of a stainless steel thin tube (sheath), a conducting wire, the element of the resistance thermometer sensor inside the tube, and an inorganic insulator (magnesium oxide, MgO) firmly packed and insulated around them.
Various structures are available according to the purposes of use.

Protection Tube Type Resistance Thermometer Sensors

They are conventional resistance thermometer sensors whose structure is to protect resistance elements from the atmosphere of measuring targets.
Currently, sheathed resistance thermometer sensors are more widespread than the protection tube type; however, the protection tube type is more widespread since manufacturing is difficult and there is a limitation on costs with the sheath type.
