How does a thermowell work
WebA thermowell with a tapered stem guarantees a short response time and, at the same time, offers a high rigidity. With protection tubes, the straight tube design is the most widely … WebA thermistor sensor is a temperature-sensing element composed of sintered semiconductor material which exhibits a large change in resistance proportional to a small change in temperature. Thermistors usually have negative temperature coefficients which means the resistance of the thermistor decreases as the temperature increases.
