Temperature Sensors - NTC Thermistors

Thermistors are a type of temperature sensing resistor designed to produce an electrical resistance linear with temperature. NTC (Negative Temperature Coefficient) thermistors are quite popular in the application of temperature sensing due to their fast, accurate and economical responses.The 2DC302J is a NTC thermistor widely used in temperature sensing applications. It is encapsulated in a glass body for protection and accurate stability in different operating conditions. The 2DC302J is an ideal sensor to monitor the temperature in environments such as industrial control systems and medical systems, where wide temperature variations happen and a fast response is important.

Working Principle

The 2DC302J NTC thermistor works on the principle of thermally sensitive resistance change. When the temperature of the NTC thermistor increases, its electrical resistance decreases. The 2DC302J thermistor has an operating range of -40 to 150 °C.The 2DC302J thermistor is a two-electrode device which when exposed to a temperature change, produces a voltage or current signal which reflects the temperature change. The circuit is composed of three elements, the 2DC302J thermistor, the load resistor, and the voltage source. The operating voltage applied across the NTC thermistor provides a current (I) through the load resistor. The voltage across these two components is the output voltage.

Application Field

The major application of 2DC302J thermistors is in temperature sensors, safety interlock systems, fire alarm systems, and over-temperature protection systems. Besides these, they are widely used in cooling systems, heating elements, air conditioners, ovens, refrigerators, and many domestic and industrial applications.2DC302J thermistors are excellent devices for use in applications that require fast response, good accuracy, and low cost. They can be used to measure the temperature of environments, liquids, and surfaces, making it the ideal temperature sensing device for various industries.The most important features of 2DC302J thermistor are its high temperature stability and high resolution, making them ideal for precise temperature measurements. They are also very reliable and can be used for applications with wide temperature ranges. 2DC302J thermistors can be used in both analog and digital systems and can be connected to any compatible temperature monitoring system. These NTC thermistors offer fast response time and high sensitivity, making them the perfect choice for accurate and reliable temperature sensing.
