Fast Response Temperature Probes

 

Some temperature control applications, such as domestic showers and instant water heaters, require a very fast thermal response of 1 second or less. Therefore maximising thermal efficiency, and avoid potential scalding.

In response to this, ATC Semitec stock a number of very fast-response probes where the NTC thermistor is situated in the very tip of the sensor. This reduces the thermal path to the thermistor and thus minimises the thermal response time. Response times can be further accelerated by using our thin wall tip or exposed NTC sensor.

Our standard sensor packages include – screw threaded bosses, bayonet fittings and push-fit/clip-in designs -all available with flying leads and/or industry standard connector options.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.
