Free shipping for many products! When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to measure the temperature of the environment, this electrical heating may introduce a significant error (an observer effect) if a correction is not made. Alternatively, this effect itself can be exploited. It can, for example, make a sensitive air-flow device employed in a sailplane rate-of-climb instrument, th… chrysler minivan town and countryWebFor 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. chrysler misfire monitor status waiting
