What is Thermistor What is Thermistor : The thermistor is a word formed by combining thermal with a resistor. Thermistors such as RTDs are temperature – sensitive resistors. Thermistors are non-linear devices. Their resistance will decrease with an increase in temperature but at a much faste/rate than that of RTDs. The resistance can change by more than 1000 times. As a result, thermistors can sense minute changes in temperature which are undetected RTDs and thermocouples. The basic ... What is a Thermistor ? A thermistor is a type of thermal resistor whose electrical resistance increases or decreases with a change in temperature. Thus, the thermistors are thermally sensitive resistance whose resistance changes with a change in the thermistor ’s body temperature. We will discuss the working principle of thermistors. How PTC and NTC thermistors function and the applications of thermistors will be discussed in the later sections. Thermistors The Thermistor is a special type of variable resistive element that changes its physical resistance when exposed to changes in temperature. Key learnings: Thermistor Definition: A thermistor (or thermal resistor) is defined as a resistor whose electrical resistance varies significantly with changes in temperature. Uses of Thermistors: Thermistors are used in digital thermometers, automotive applications, household appliances, and circuit protection. Working Principle: Thermistors work by changing their resistance with temperature; this resistance is measured to determine the temperature. NTC and PTC Thermistors: NTC thermistors ...
