How to Test a Thermistor - Learning about Electronics

How to Test a Thermistor. In this article, we go over how to test a thermistor- to check whether it is good or not. A thermistor is a resistor whose resistance changes according to the temperature it is exposed to.. There are 2 main types of thermistors: negative temperature coefficient (NTC) thermistors and positive temperature coefficient (PTC) thermistors.

Dometic™ Duo-Therm RV Air Conditioner ...

The thermistor is a temperature sensor that sends signals to the control board. One end is conected to the evaporator coil, the other to the control board. If the thermistor senses the evaporator coils are freezing over during operation, the control board will shut off the air conditioner. Requiring you to manually turn the A/C off and back on from the thermostat. Compatible with Dometic A/C ...

What Is An NTC Thermistor | Ametherm

Sensors Online. NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K.

Thermistors and NTC Thermistors

The Thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a transducer.

What is a Thermistor and how does it work?

Aug 28, 2018· What does "thermistor" mean? Thermistors, derived from the term thermaIly sensitive resistors, are a very accurate and cost- effective sensor for measuring temperature. Available in 2 types, NTC (negative temperature coefficient) and PTC (positive temperature coefficient), it is the NTC thermistor that is commonly used to measure temperature.
