BTS4 Push-Fit Temperature Sensors
A range of push-fit/clip-in temperature sensors in brass housings fitted with integral o-rings. The push-in sensor /probe is held in situ by a circlip which makes them suitable for use in polymer composite heat exchangers in district heating systems.
This sensor design is perfect for polymer heat exchangers where a screw-threaded boss sensor would not withstand the high fluid pressures involved. The sensors can be fitted with a range of NTC thermistors or platinum RTD Pt100 or Pt1000 elements.
Various industry standard connectors or integral lead-wires are available.
Applications
- Gas boilers
