How does a thermistor measure temperature
WebThe thermistor Thermistors are used as temperature sensors, for example, in fire alarms. Their resistance decreases as the temperature increases. At low temperatures, the resistance of a... WebTesting 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 …

WebApr 12, 2024 · Thermistors work best when measuring a single temperature within the range between -55°C and +114°C i.e. when measuring within 50°C of ambient; extremely high or low temperatures don’t get recorded correctly. Using a thermistor where the … WebFor example, let’s say that you measured one thermistor with a 0-100 °C temperature change and you measured the other thermistor with a 0-50 °C. Because the driving force behind the thermal time constant is the temperature difference; the first thermistor you measured will have a shorter measurement and quicker response time.
WebSep 18, 2024 · For example a thermistor may be 10K nominal at 25°C but only 516 ohms at 125°C, and 210K at -40°C. There are some PTC thermistors designed for measuring temperature, they tend to have more gentle temperature coefficients (such as the silicon resistance types). WebA demonstration investigating the relationship between thermistor temperature and resistance including how to test for inverse proportionality.
