How to test your Thermistors - Sensor Sci

Jun 23, 2019· NTC thermistors have their resistance decreased when the temperature increases. The steps include: Prior doing anything, check the rated value of the device (100Ω, 1KΩ, 10KΩ). Set resistance value close to its rated resistance value. If this is not possible, meaning that the thermistor cannot get close to the rated value, the thermistor is ...

What is a Thermistor and how does it work?

Aug 28, 2018· 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.
