Temperature Sensors - NTC Thermistors

NTC thermistors, such as model NTHS1012N04N1003JF, are temperature sensors. In electronics, they are often used to sense an increase or decrease in temperature and to regulate when that temperature reaches a certain point. The thermistor works by responding to the changes in temperature by resistance. The resistance of the thermistor increases as the temperature decreases and vice versa.

Application Field

NTC thermistors have a variety of applications which can be found in both commercial and consumer products. In automotive, they are commonly used for sensing the temperature of the engine coolant, the air intake, and the air conditioning system. Additionally, they can be used as a heat sensing element in refrigerators, providing feedback for the thermostat. In industrial applications, NTC thermistors are often used in temperature controlling systems and monitoring systems.

Working Principle

NTC thermistors work by having temperature-dependent electrical resistances. Temperature affects the electrical resistance of the thermistor material, making it more resistant on lower temperatures and less resistant on higher temperatures. The operating principle of these thermistors is governed by the temperature coefficient of resistance (TCR). This states that the resistance value of the thermistor changes with temperature in inverse proportion, meaning that the decrease in temperature causes an increase in R-value.

This principle is used to create a temperature sensing circuit. The thermistor is connected in a series circuit, allowing current to flow and supplying voltage to the thermistor. As the temperature of the thermistor changes, the resistance value of the thermistor also changes, and thus the amount of current flowing through the thermistor also changes. This change in current can be used to measure the temperature of the thermistor.

Conclusion

The model NTHS1012N04N1003JF is a temperature sensor, also known as an NTC thermistor. It has many real-world applications such as automotive and industrial temperature sensing and feedback. Its operating principle is governed by the temperature coefficient of resistance and it works by increasing its resistance as the temperature decreases and vice versa. This change in resistance can be used to measure the temperature.
