Waterproof Temperature Sensors

For an ultra-reliable, waterproof temperature sensor with IP67 or IP68 integrity, then look no further than our range of TPE-encapsulated sensors.  These over-moulded NTC Thermistor probes use the same TPE moulding material as the integral lead-wire’s insulation.  By using double-insulated or single-insulated TPE cable, a true waterproof seal is created by the fusion of the two insulating materials making the sensors suitable for direct immersion in the media being measured.  This makes them ideal for refrigeration, air-conditioning, underfloor heating and heat pumps, solar and other green energy solutions.

Our IP67 and IP68 waterproof sensors can be fitted with any NTC Thermistor from our AP-2, AT-2, ATCD, NT-4 or SP series ranges.  From this very wide range of R25 and B values, we can match or fine-tune the sensor specification to meet your application requirements.  Also Pt100, Pt500 or Pt1000 RTD elements are now available in IP67 or IP68 versions.

Cable lengths can be supplied from 100 mm up to 10 metres long so that you have a single uninterrupted sensor cable helping to ensure product integrity.  Metal tips or stainless-steel housings can be added to help increase their physical robustness where an abrasive sensing environment could be encountered.  For even harsher environments, shielded cable options and armoured cabling is also available.

For high volume applications, these sensors can also be supplied with integral terminals or connectors to help them fit directly into your product.

Typical applications for these waterproof temperature probes include:

  • Heat Pumps and Solar Panels
  • Refrigeration & Air Conditioning
  • Mechanical Ventilation Heat Recovery Systems (MVHR)
  • Underfloor Heating Control
  • Battery Module Temperature Monitoring
