Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors that are widely used in electronic applications. They can respond to changes in temperature quickly, accurately, and reliably. In this article, we will discuss the application field and working principle of the ABNTC-0402-333J-3500F-T sensor.

What is an NTC Thermistor?

NTC stands for negative temperature coefficient thermistor. This type of thermistor is made of a sintered semi-conductor material that is usually composed of metal oxides. Its resistance decreases as the temperature rises, and vice versa. This makes them ideal for use as temperature sensors and for precision temperature measurements in industrial and medical devices.

Application Fields

Due to their fast response time, accuracy, and reliability, NTC thermistors have become popular in a wide variety of applications. They are most commonly used in consumer electronics, automotive, industrial, and medical applications. These applications include:

• HVAC Systems
• Refrigeration and Air Conditioning Systems
• Automotive Electronics
• Various Industrial Process Control Systems
• Medical Devices and Equipment

NTC thermistors can also be used in thermal protection circuits. These circuits will cut off the power supply if a certain temperature threshold is reached, protecting the device or system from damage or malfunctioning.

Working Principle

The ABNTC-0402-333J-3500F-T sensor works on the principle of negative temperature coefficient. As the temperature increases, the resistance of the thermistor decreases. This can be explained with the help of a simple equation:

R = R0 * exp (-B/T)

Where R is the resistance at a certain temperature T, R0 is the resistance at a reference temperature, and B is the temperature coefficient. This equation is known as the Steinhart-Hart equation and is used to accurately calculate the temperature by measuring the resistance of the NTC thermistor. The theoretical resistance of the ABNTC-0402-333J-3500F-T sensor at 25 degrees Celsius is 2800 ohms.

Conclusion

NTC thermistors are widely used in electronic applications due to their fast response time, accuracy, and reliability. The ABNTC-0402-333J-3500F-T sensor has a theoretical resistance of 2800 ohms at 25 degrees Celsius and works on the principle of negative temperature coefficient. It is most commonly used in HVAC, refrigeration and air conditioning systems, automotive electronics, industrial process control systems, and medical devices and equipment.
