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.

Product Details:

For temperatures between -50 (-200) to +600 °
• Flexible sheath cable with vibration-resistant measuring insert
• As single or double RTD temperature probe in 2-wire, 3-wire, or 4-wire circuit
• Quick response time
• Application-specific insertion length
Due to their specific features, mineral-insulated RTD temperature probes are used in chemical
plants, power plants, pipelines, engine building, test rigs, and any measuring locations requiring
flexibility and simple replacement. Inside the flexible and thin-walled sheathed cable out of
stainless steel, the low ohmic conductor copper wires are embedded in compressed, heat-resistant
magnesium oxide.
The temperature sensor with 2-wire, 3-wire, or 4-wire technology is connected to the conductor
copper wires and installed in the protection tube out of stainless steel. The protection tube and
sheathed cable are welded to one another. The diameters already start at 1.9 mm.
The good thermal transfer between the protection tube and temperature sensor enables short
response times (t0.5 from 0.7 s) and excellent measuring accuracy. The vibration-resistant construction
guarantees a long operating life. The flexible probe tube allows temperature measurements
to be made at measuring points that are difficult to access. The smallest bending radius
is 5 times the outer diameter.
The measuring insert is normally fitted with a Pt100 temperature sensor according to DIN EN
60751, class B in 2-wire circuit; versions with Pt500 or Pt1000 can be ordered as well. The connection
is also available in 3-wire and 4-wire circuits.
