Screw-in RTD temperature probes
with connecting cable
■ for temperatures from -50 to +400°C
■ as single or twin RTD temperature probe
■ in 2-wire, 3-wire or 4-wire circuit
■ connecting cable in PVC, silicone, PTFE or with metal braiding
Screw-in RTD temperature probes are mainly used for measuring temperatures in liquids
and gases. An important selection criterion is their reliable sealing against both negative
and positive pressures. Applications include HVAC, refrigeration, heating installations, ov-
ens, furnaces and plant engineering.
Depending on the version, the connecting cables are suitable for use in dry and humid ar-
eas within the temperature range -50 to +350°C. The junction between cable and protec-
tion tube incorporates strain relief. A cable protector can be supplied as an option.
The measuring insert is normally fitted with a Pt100 temperature sensor to EN 60 751,
Class B in 2-wire circuit. Versions with Pt500 or Pt1000 are also available. In addition,
there is a choice of 3-wire or 4-wire circuit connections.
