NTC thermistors are temperature sensing semiconductors that can measure temperature with extraordinary accuracy. NTC stands for "Negative Temperature Coefficient", which means that the thermistor\'s resistance decreases as the temperature increases. The KT103G2 is a cutting-edge NTC thermistor designed for a wide range of temperature sensing applications. This article will discuss the application field and working principle of the KT103G2.

Application Field

The KT103G2 thermistor can be used in a wide variety of temperature sensing applications such as HVAC systems, medical monitoring systems, automotive electronics, and consumer appliance applications. Its small size and high accuracy makes it an ideal choice for applications where space is limited and accuracy is essential. The thermistor has a range of -40°C to 125°C, making it suitable for use in a range of environments from cold storage stores to high-temperature industrial settings.

The KT103G2 is also suitable for use in monitoring and controlling temperature in closed systems. Its tight-tolerance ensures that the temperature can be accurately measured and monitored over long periods of time, ensuring that any fluctuations are noted and quickly corrected. This makes the KT103G2 a reliable choice for use in industry and medical applications.

Working Principle

The working principle of the KT103G2 thermistor is based on the negative temperature coefficient (NTC) of semiconductors. As temperature increases, the resistance of the thermistor decreases. This change in resistance can be measured to calculate the temperature. The KT103G2 is unique in that it utilizes a special silver-based wire instead of the usual manganese-oxide used in standard NTC thermistors. This gives the thermistor a much higher temperature sensitivity than other thermistors.

The thermistor’s resistance is measured using a bridge circuit. This consist of four legs, three resistors and the NTC thermistor. The output voltage of the bridge is measured and is proportional to the temperature. The bridge is connected to a data acquisition system or an analog-to-digital converter to provide a digital output. This signal can be used to measure and control the temperature.

The KT103G2 thermistor is designed to be robust and reliable, with an extremely stable resistance-temperature curve. The resistance-temperature relationship is linear, which makes the thermistor ideal for use in closed-loop control systems. This enables temperature control with high accuracy, even when the environment is constantly changing.

Conclusion

The KT103G2 thermistor is an advanced NTC thermistor that can be used in a wide range of temperature sensing applications. Its small size and high accuracy make it an ideal choice for applications where space is limited and accuracy is essential. The thermistor’s high temperature sensitivity and linear resistance-temperature relationship make it suitable for use in closed-loop control systems. This makes the KT103G2 thermistor an excellent choice for temperature sensing in both industry and medical applications.
