How to Test a Thermistor - Learning about Electronics

How to Test a PTC Thermistor. Testing a PTC thermistor follows all the same steps as a NTC thermistor. First check, with an ohmmeter, the thermistor without any heat applied. With a PTC thermistor at room temperature or below, the thermistor should measure a very low resistance. Now apply heat, just like before, to the thermistor's body. The resistance of the PTC thermistor should …

Thermistors in Single Supply Temperature Sensing Circuits

the thermistor sensor can be used to time delay a reaction to changes in conditions in a circuit. If a thermistor is overdriven, the thermal mass time constant of the sensor eventually causes the thermistor to overheat, reducing its resistance. Resistance-Versus-Temperature Mode By far, applications using the first mode, resistance-ver- sus-temperature, NTC Thermistor configurations, …

Thermistor-Working Principle, Types and Applications

04/03/2020· To test a thermistor sensor we can use an analog multimeter. The steps followed on testing the thermistors are: Connect the analog multimeter to the thermistor leads. There is no consideration for polarity. By using the soldering rod of iron we can heat the thermistor. Once the heat in the thermistor tends to change the values in the multimeter are about increase or decrease. The …
