Thermistors (THMS)

Thermistors are composed of semiconductor materials that indicate absolute temperature by their resistance. While related to RTD’s they are more limited in overall operating range, and change resistance differently. Although Positive Temperature Coefficient (PTC) units are available, most thermistors have a negative temperature coefficient (NTC); that is, their resistance decreases with increasing temperature. The change in temperature can be as large as several percent per degree Celsius, allowing the thermistor to detect minute shifts in temperature, which could not easily be observed with an RTD or thermocouple. It is for this reason that they are perfectly suited to measure cabin air temperature as part of an Air Management System (AMS).
