Sheath resistance thermometers comprise a thin-walled and flexible sheathed cable made of stainless steel. The cable contains low resistance inner wires made of copper embedded in pressed fireproof magnesium oxide. The temperature sensor is connected to the inner wires and fitted in a protective tube.
Protective tube and sheathed cable arewelded together. Good heat transfer between protective tube and temperature sensor allows fast response times and high measuring accuracies. The vibration-proof design assures long service life.
The flexible probe tube allows temperature measurements at locations that are difficult to access. The minimum bend radius is 5 x outer diameter. Pt 100 temperature sensors according to IEC 751, category B are used as standard.
