Continuous Temperature Sensing

Therm-O-Disc NTC thermistors offer economical, reliable and accurate solutions to those applications requiring more extensive sensing than the one or two temperature points typically offered by a bimetallic thermostat. NTC thermistors provide a change in resistnace with temperature that when combined with an electronic circuit provides a means of continuously measuring temperature over a very wide range.

NTC Thermistor Features

•Economical

•Long-term stability

•Accurate

•A wide variety of packaging options available

Operating principle of NTC Thermistors

NTC thermistors are a semiconductor ceramic made with various metal oxides. Their electrical resistance decrease with increasing temperature. This resistance is processed by an electronic circuit to provide temperature measurement. While a bimetallic thermostat provides both temperature sensing and electrical circuit control, the thermistor itself does not provide any control over heating elements, relays, etc. The thermistor is strictly a sensor and any electrical control would need to be implemented by the circuit utilizing the thermistor.
