Screw-in RTD temperature probes
with terminal head form B
• For temperatures from -50 to +600 °C
• With replaceable measuring insert
• As single or double RTD temperature probes
• Connection head form B, BUZ, BUZH, BBK
• Available with transmitter

Screw-in RTD temperature probes are mainly used for measuring temperatures in fluids and gasses. A decisive selection criterion is the reliable sealing feature of this installation type with vacuum and with overpressure. The application areas are, among others, in the air conditioning technology and refrigeration engineering as well as the HVAC, kiln and apparatus engineering sector.
The connection head is suitable for temperatures up to +100 °C. The versions BUZ, BUZH and BBK are also available in addition to the standard connection head, form B.
A Pt100 temperature sensing element according to DIN EN 60751, class B in 2-wire circuit is used as a measuring insert by default – versions with Pt500 or Pt1000 are also possible. Connection is available in 3-wire or 4-wire circuit as an option. A transmitter can be optionally integrated into the connection head.
