Introduction

The GL502F5J is a temperature sensor in the form of an NTC thermistor. Developed for resistance measurement, NTC thermistors are used in a wide range of temperature monitoring and control applications and are commonly used in applications that require accurate and reliable temperature measurement. This document outlines the application field and working principle of the GL502F5J, and also gives an overview of its features and technical characteristics.

Application Field

The GL502F5J is used mainly in automotive, medical and industrial applications. In automotive applications, the GL502F5J is used to measure air and engine temperature, fuel temperature, and radiator temperature. The GL502F5J can also be used in applications such as medical devices, refrigerators, air conditioners and home appliances.

Working Principle

The GL502F5J uses a negative temperature coefficient (NTC) thermistor to measure temperature. An NTC thermistor is a semiconductor device made from metal oxides that has a negative coefficient of resistivity; that is, it has a resistance that decreases as the temperature increases. The GL502F5J uses a bismuth wheel with a metallic bridge connected to a platinum needle as its sensing element. When temperature changes result in a change in resistance, the bridge will move away from the needle, and the bismuth will move the sensitive materials between the metallic bridge and the needle. This produces an electrical signal, which is then converted into a temperature signal by the GL502F5J.

Features and Technical Characteristics

The GL502F5J has several features and technical characteristics that make it an ideal temperature sensing solution. The device temperature range is -40°C to 125°C and its linear temperature coefficient is -1% of resistance per degree Celsius. The device has a wide range of resistance values (2k - 17k ohms) and a high accuracy rating of 0.5-1%. The GL502F5J also has a low power consumption of 5 mW, which makes it suitable for battery-operated applications. It is designed for applications that require a robust design and is resistant to shocks, vibration, and other forms of mechanical stress. The device is also RoHS compliant and has a durable housing which helps protect against environmental elements.

Conclusion

The GL502F5J is an ideal temperature sensing solution for a wide variety of applications. Its high accuracy rating, wide temperature range, and low power consumption make it suitable for automotive, medical, and industrial applications. Its robust design also makes it resistant to shocks, vibration, and other forms of mechanical stress. Therefore, the GL502F5J can be used as an accurate and reliable temperature sensing solution in a variety of applications.
