NettetPTC thermistors are also known as motor protectors, PTC resistors, or motor protection sensors. Precise & Accurate Measurements Thermistors (a word combining thermal and resistor) are negative coefficient resistors that measure and control specific temperatures. NettetNTC Thermistors. Negative temperature coefficient (NTC) thermistors have a resistance which reduces as the temperature rises (fig 1.). They are used for resistance thermometers in temperature measurement and all Sterling Sensors assemblies are made using this type of thermistor. Fig 1. (NTC Thermistor graph)
