Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors used to measure and control temperature in a wide variety of applications. NTC thermistors are one of the most common temperature sensors used due to their robustness, accuracy, cost effectiveness and reliable performance. The B57871S0103J002 is a NTC thermistor specifically designed for temperature sensing and control applications.

Application Field

NTC thermistors like the B57871S0103J002 can be used for temperature measurement and control in any environment. They are commonly used for HVAC, automotive, and consumer electronics applications. In HVAC applications such as air conditioners, dehumidifiers, and refrigerators, the NTC thermistor can be used to detect the temperature outside the system and regulate the temperature within the system itself. NTC thermistors can also be used in a variety of automotive applications such as temperature sensors inside cars, motorcycle and ATV engines, and engines of marine vehicles. These temperature sensors are often found in consumer electronics such as laptops, phones, and tablets to ensure efficient operations.

Working Principle

NTC thermistors, including the B57871S0103J002, work on the principle of resistance. They are composed of a ceramic material with embedded metallic conductive paths. The resistance of the device changes with changes in temperature. At a high temperature, the resistance of the device is low; at a low temperature, it is high. The thermistor has a known temperature range, which is usually indicated with a Beta value. The Beta value is the ratio of resistance at two specific temperatures, usually 25°C and 50°C.

The resistance of NTC thermistors can be read out by taking voltage measurements with an ohmmeter, or by using a Wheatstone bridge circuit. This makes them ideal for automated temperature sensing and control. The resistance of the thermistor can be incorporated into a control loop, allowing the thermistor to be used to automatically regulate temperatures in different applications, such as thermostats. In this way, the thermistor can be used to detect temperatures outside of its stated range and is therefore useful for a variety of measurement and control applications.
