SMD Surface Mount RTD Sensor Elements

By definition – NTC thermistors are highly sensitive thermal resistors that respond very quickly to rapid changes in temperature- the word thermistor itself is a contraction of “thermal” and “resistor”.

NTC thermistors are so-called because of the resistance of an NTC decreases with an increasing temperature and their R-T (Resistance – Temperature) is very accurately defined. The R-T accuracy combined with the fast rate of change (compared to RTDs and thermocouples) makes them ideal to incorporate in electronics control circuitry

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.

ATC Semitec stock a wide range of thermostats from several world leading, innovative manufacturers. Whether your application is sensing air temperature in the central heating or air conditioning market sector, or surface temperature sensing on heating elements in home appliances, we will have a product which to suit your needs.

Our leading brands include PEPI (Portage Electric Products Inc), Asahi, Matsuo and Campini who form a comprehensive range of thermostats each offering specific benefits.

PEPI thermostats provide accurate temperature control and thermal protection from 5°C to 200°C. With calibration tolerances of ±3K and temperature differentials as small as 10K (or even smaller in creep-action designs) a PEPI thermal switch offers the best control to cost ratio available.  Typical applications include rechargeable batteries, small appliances and electric heater control.
