Temperature Sensors - NTC Thermistors

NTC thermistors are widely used in temperature sensing applications due to their high accuracy and reliability. The NTC thermistor of NB21PC0472JBB is a specialized type of thermistor, with unique features that make it well-suited for applications where exact temperature readings are essential. This article will discuss the application field and working principle of the NB21PC0472JBB.

Application Field: The NB21PC0472JBB is an NTC thermistor specifically designed for use in laboratory and medical applications. It can measure temperatures from 32 °F (0 °C) to 302 °F (150 °C) with an accuracy of 0.1°C, making it ideal for applications such as HVAC systems, food and beverage processing and storage, industrial processes, medical equipment, water cooling systems, and automotive applications.

Working Principle: The NB21PC0472JBB is a semiconductor device consisting of a ceramic core with an internal layer of resistive material sandwiched between two metallic surfaces. The resistance of the device to current is directly proportional to temperature. When the temperature increases, the resistance of the device decreases; conversely, when the temperature decreases, the resistance of the device increases. This effect is called the "thermistor\'s negative temperature coefficient (NTC)". The thermistor responds to rapidly changing temperatures with excellent accuracy.

The NB21PC0472JBB is an economical, high-performance thermistor with a high precision accuracy of 0.1°C and a wide temperature range from 32 °F (0 °C) to 302 °F (150 °C). The device is highly linear and exhibits excellent response characteristics, making it ideal for applications where exact temperature measurements are a must. The device has low power dissipation, making it suitable for energy-conscious applications. It also has excellent high-temperature endurance and is resistant to vibration and mechanical shock, making it suitable for industrial and automotive applications.

The NB21PC0472JBB is connected to an electrical circuit, allowing it to detect changes in temperature and send a corresponding electrical signal to the circuit. This signal is then amplified and used to power a temperature controller, allowing for accurate temperature control. The device is often used in combination with a temperature controller, such as a PID controller, allowing for precision temperature regulation.

Overall, the NB21PC0472JBB is a reliable and economical NTC thermistor that can be used in a wide range of temperature sensing applications. Its precision accuracy, wide temperature range, excellent response characteristics, and high-temperature endurance make it well-suited for laboratory, industrial, medical, automotive, and other temperature-sensing applications.
