What is a thermistor sensor?

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.

How does a thermistor sensor work?

Thermistors change resistance with temperature changes; they are temperature-dependent resistors. They’re perfectly suited to scenarios where one specific temperature needs to be maintained, they’re sensitive to small changes in temperature. They can measure liquid, gas, or solids, depending on the type of thermistor.

What is the use of a thermistor?

Thermistors are used as temperature sensors. They can be found in every day appliances such as fire alarms, ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature.

What is the difference between a thermistor and other sensors?

The most significant difference between the thermocouple and the thermistor is that in thermocouple the sensing parameter is the voltage that induces between the two dissimilar metals. Whereas in thermistor the resistance is the temperature sensing parameter.

How does a thermistor temperature sensor work?

An AC thermistor is a type of temperature sensor that is commonly found on modern AC systems. They detect temperatures and send a resistance signal to the AC control module so that the automatic adjustments can be made to keep the cabin at the correct temperature.

What is a thermistor and how does it work?

A thermistor is a resistor, or type of sensor used to regulate and measure temperature, such as heat and cold. A thermistor is made up of ceramic with a high precision at a specific temperature level. The thermistor contains electrical networks, circuits and wires. The main characteristics of a thermistor are: power, noise,…

How is thermistor used in a thermostat?

Thermostats often use a sensor like Thermistor to measure the temperature . A Thermistor is a temperature sensitive resistor where its resistance changes according to its surrounding temperature.
