The insertion resistance thermometers comprise a rugged sensor made of stainless steel. Due to the special form of the probe tip, these temperature detectors are suitable for service in threaded borings.
The thermostable compression spring made of stainless steel, which also acts as bend protection, ensures steady contact pressure of the probe tip in the hole. The immersion length can be varied by rotating the bayonet lock.
Bayonet locks and counterparts are available in 6 and 8 mm diameter, others upon request.
Pt 100 temperature sensors according to IEC 751, class B are used as standard. Other categories or versions are also available with Pt 500 and Pt 1000. These sensors are available as single or double resistance thermometers.
The screw-in resistance thermometers are available in two-, three- or four-wire circuitry.
