Waterproof Temperature Sensors

When you need a reliable, waterproof temperature sensor with IP67 or even IP68 integrity, then look no further than these TPE-encapsulated sensor ranges.  These over-moulded thermistor sensors use the same moulding material as the integral lead-wire’s insulation thus creating a true waterproof seal.  This makes them ideal for refrigeration, underfloor heating, heat pumps and other green energy solutions.

These waterproof sensors can be fitted with any thermistor from our AP-2, AT-2, ATCD, NT-4 or SP series ranges, meaning that we can match an extremely wide range of R25 and B values to match your existing application.  Cable lengths from 100mm upto 10m (or even longer) ensures that you have a single uninterrupted sensor for your product security.  Metal tips or stainless steel housings can be added to help increase their physical robustness where an abrasive sensing environment could be encountered.

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

Typical applications for these waterproof temperature probes include:

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