Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors which are composed of a negatively temperature-coefficient resister. While the resistance of a normal resistor remains the same over a wide temperature range, the resistance of an NTC thermistors, as its name implies, decreases as the temperature rises. This behaviour is caused by the Curie or Néel effect. This effect causes the resistance of a solid material to change with a change in its temperature. By exploiting this effect, NTC thermistors can be produced to work over a specific temperature range.

2322 641 66153 Application Field and Working Principle

The 2322 641 66153 is an NTC thermistor temperature sensor. It is designed to work in a temperature range from –40 to 130°C. It is commonly used in applications such as motor protectors, over-temperature detections, temperature alarms, and air conditioners. It is also widely used as a temperature sensor in automotive applications.

The working principle of the 2322 641 66153 can be explained as follows: The thermistor is connected in series with a current-limiting resistor and placed in an enclosure with a given temperature. As the temperature changes, the NTC thermistor’s resistance will also change, which in turn will affect the current in the circuit. This current can then be measured by an external electronic device such as a microcontroller and used to calculate the temperature of the environment.

Advantages of NTC Thermistors

NTC thermistors have a number of advantages over other types of temperature sensors. Firstly, they are very small and simple in design, so they can be easily implemented into a wide range of applications. Secondly, they are relatively inexpensive compared to other types of temperature sensors. Thirdly, they are very accurate and reliable, meaning that they can be used for high-precision temperature measurements. Finally, they are very fast in responding to changes in temperature, making them ideal for fast response applications such as motor protectors.

Conclusion

NTC thermistors are widely used temperature sensors that are widely used in a variety of applications, from motor protectors to air conditioners. The 2322 641 66153 is an example of such a thermistor, which is designed to work in a temperature range from –40 to 130°C and has a number of advantages over other types of temperature sensors. These advantages include a small size, low cost, high accuracy and a fast response to changing temperature.
