Introduction

Temperature Sensors - NTC Thermistors are the most widely used and most versatile type of temperature sensing devices. This is because of their low cost, easy implementation, and easy-to-understand working principle. Thermistors are temperature-dependent resistors in which the resistance decreases with increase in temperature. The most common type of thermistor is the NTC (Negative Temperature Coefficient). In this paper, we will discuss the application field and working principle of the PS102J2 NTC thermistor in detail.

Application Field

The PS102J2 NTC thermistor is most commonly used in temperature sensing and control applications. It is used in consumer appliances such as refrigerators, air conditioners, and electric kettles, and in industrial and automotive applications where temperature control is critical to the operation of the system. The PS102J2 thermistor can also be used in a range of non-temperature sensing applications, such as detecting the presence of water or pressure.The PS102J2 thermistor is also suitable for use in enclosed spaces, with a wide temperature range (-50°C to 110°C). This makes it an ideal choice for applications where small size and good temperature stability are important.

Working Principle

The PS102J2 thermistor has a simple and straightforward working principle. When exposed to a temperature change, the thermistor\'s resistance value also changes. This change in resistance is known as the NTC effect. The resistance value of the PS102J2 thermistor decreases as the temperature rises.At 0°C, the resistance value is 123kΩ. At 25°C, it is 116kΩ, and at 100°C, it is 97.9kΩ. As the temperature increases, the resistance value decreases in a predictable way. This makes it easy to measure temperature changes, since the resistance value can be measured and compared against a known value to determine the corresponding temperature.

Conclusion

The PS102J2 NTC thermistor is an excellent choice for temperature sensing and control applications due to its low cost, small size, and simple working principle. It is widely used in both consumer and industrial applications, with a wide temperature range and good temperature stability. The NTC effect also makes it easy to measure temperature changes, since the resistance of the thermistor can be directly measured and compared against known values.
