AN-1984LM57 Temperature Switch vs Thermistors

indication have traditionally used a thermal-resistor(thermistor) for a sensor element (Figure 1). The most commonly used thermistor is a negative-temperature-coefficient(NTC) thermistor; as temperature increases, the resistance of the NTC thermistor decreases. For a system processor to utilize the temperature information from a thermistor, the temperature-to-resistanceparameter is generally ...

Thermistor-Working Principle, Types and Applications

2020-03-04· How do you test a Thermistor Sensor? 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 …

NTC THERMISTOR TESTING CONSIDERATIONS

If the thermistor under test and the independent temperature sensor are both in a protective housing then water can be used. If the thermistor is bare or has exposed leads then a non-electrically conductive liquid must be employed such as mineral spirits or oil. In the high temperature realm, there are some cautions. Oils can produce smoke and fumes and should have a fume hood and power vent ...
