Introduction

NTC thermistors are temperature sensors that measure the temperature by using the change in electrical resistance through a metal oxide semiconductor material. The PR222J2 is a type of NTC thermistor that is often used in industrial and consumer applications to monitor and control temperatures, as well as to provide an accurate measurement of a system’s temperature. This article will discuss the application field and working principle of the PR222J2 temperature sensor.

Application Fields

The PR222J2 thermistor has a wide range of applications. It can be used in industrial and consumer temperature sensing applications, such as in medical systems, batteries, military equipment, and data center applications. Additionally, the PR222J2 can be used in automotive manufacturing applications, as well as in heating and cooling equipment. The PR222J2 is designed to measure and control temperature in a range from -50°C to +200°C. This makes it an ideal choice for measuring temperature in extreme temperatures. It is also designed to be stable and accurate in low temperature ranges.

Working Principle

The PR222J2 thermistor works on the principles of thermistor resistance change with temperature. When the temperature of the PR222J2 thermistor increases, its resistance decreases, and vice versa. The PR222J2 thermistor has a temperature coefficient of resistance (TCR) rating of -4.25%/K which means that the thermistor’s resistance will decrease (or increase) by 4.25% for every Kelvin of temperature change. The PR222J2 thermistor is composed of a conductive metal oxide semiconductor material. In order for the thermistor to measure temperature accurately, it must be connected to an appropriate voltage source. When the thermistor is connected to a voltage source, it produces a current, which then passes through the thermistor’s material. The resistance of the material changes in response to the temperature, which results in the current changing accordingly. This data can then be used to determine the temperature of the PR222J2 thermistor.

Conclusion

The PR222J2 thermistor is a type of NTC thermistor that is used for temperature sensing and control applications. It has a wide range of applications, including industrial and consumer applications, as well as automotive manufacturing and heating and cooling equipment. It is designed to measure and control temperature in a range from -50°C to +200°C, and has a temperature coefficient of resistance (TCR) rating of -4.25%/K. The PR222J2 thermistor works on the principles of thermistor resistance change with temperature, and it must be connected to an appropriate voltage source in order to measure temperature accurately.
