Conventional insulation thermocouples and resistance temperature detectors
Conventional insulation thermocouples (type "J" and "K") and resistance temperature detectors (PT100) are commonly used when working conditions are critical such as for instance in case of vibrations and mechanical stress. These sensors are produced in accordance with IEC or DIN rules. A wide range of mechanical solutions is available, such as clamp screws, eyelet mounting, bands; bayonet thermoelements.
Mineral insulation thermocouples and resistance temperature detectors
Mineral insulation thermocouples and resistance temperature detectors are covered by a highly compacted magnesium oxide sheath. These temperature sensors are used for industrial processes requiring high reliability. External diameters are available from 0,25 till 12,7 mm. Mineral insulation differs from conventional one for some specific technical features such as flexible external sheath, excellent resistance to vibrations, high speed of response, insulation resistance.
