Screw-in RTD temperature probe
with plug connector
according to DIN EN 175301

• For temperatures between -50 and +260 °C

• Vibration-resistant design

• Plug connector locked against contact, protection type IP65

• Available with transmitter

• GL approval for basic types 902044/20 and 902044/21 (max. insertion length 200 mm)

Vibration-resistant screw-in RTD temperature probes allow temperatures to be measured under
pressure in engines, compressors, plant engineering, and shipbuilding.

The plug connectors between the protection fitting and the connecting cable are locked against
contact and have protection type IP65 when connected.

The measuring insert is a Pt100 temperature sensor according to DIN EN 60751, class B in 2­wire circuit as standard. Other versions with Pt500 or Pt1000 are also possible.

The connection can be carried out in a 2-wire or 4-wire circuit as required.
Basic types 902044/25 to 902044/29 are available as versions with transmitters (output 4 to

20 mA).
