Temperature sensors, in general, measure temperature by detecting variations in physical parameters that are proportional to temperature changes. It is common for temperature sensors to use highly accurate analog instruments to perform this task. Among them, NTC thermistors are a class of temperature sensors specifically designed to measure temperatures in applications involving liquids and gases. The NB12J50472JBA temperature sensor is one of the most popular NTC thermistors used in such applications. This article provides an overview of the application field and working principle of the NB12J50472JBA temperature sensor.

The NB12J50472JBA is a type of NTC thermistor made from a semiconductive film coated with a resistive material. Its operating temperature range is typically 0°C to 100°C. It is commonly used for temperature measurement and control applications in a variety of industries, such as petrochemical, medical, automotive, aerospace, and electronics. The NB12J50472JBA is a highly accurate temperature sensor, with a temperature resolution of 0.01°C and a temperature accuracy of 0.2°C at 25°C. It is also highly reliable, with a response time of less than 1 second, and a lifespan of more than 10 million cycles.

The working principle of the NB12J50472JBA is based on the principle of electrical resistance. The sensor can measure temperature by detecting changes in its electrical resistance in response to temperature changes. The NB12J50472JBA has a resistance of around 4.7 KΩ at 25°C. As the temperature rises, the resistance of the sensor decreases. Conversely, as the temperature decreases, the resistance of the sensor increases.

The NB12J50472JBA sensor is connected to an electronic control circuit, which includes an amplifier, a power source, and a temperature-controlled circuit. The amplifier amplifies the output signal from the sensor. The power source provides power to the sensor, and the temperature-controlled circuit monitors and adjusts the temperature of the sensor. When the sensor detects a change in temperature, the signal is amplified and used to control the temperature-controlled circuit.

The NB12J50472JBA offers a high level of sensitivity, accuracy, and reliability and is commonly used in applications such as temperature measurement and control, thermal over-current protection, and over-temperature protection. It has a wide operating temperature range and is suitable for use in a variety of industrial applications, including petrochemical, medical, automotive, aerospace, and electronics. The combination of its high accuracy and reliability, coupled with its low cost, make the NB12J50472JBA a popular choice among temperature sensors.
