GL122E5J

Temperature Sensors - NTC Thermistors

NTC thermistors, or Negative Temperature Coefficient thermistors, are electronic devices that sense temperature and can be used for various purposes. A thermistor is a small, electronic component that utilizes an inherent relationship between metals and temperature in order to detect temperature levels. They are primarily used for industrial temperature sensing, medical equipment, and consumer electronics. In this article, we will discuss the application field and working principle of a GL122E5J thermistor.

Application Field

The GL122E5J is a type of thermistor which can be used to accurately detect temperatures from -40°C to +176°C, with a typical tolerance of ±1°C. The device has a variety of applications in industries where temperature sensing is key. This includes uses in home appliances, consumer electronics, automotive, medical and industrial applications. For instance, the GL122E5J can be used in food, equipment, HVAC systems, climate control systems, and various other industrial applications.

The GL122E5J thermistor can also be used to detect temperature in medical applications, primarily for monitoring vital signs such as body temperature and pulse. The device is very small and light, making it ideal for use in medical devices and equipment to measure the body temperature of a patient during a medical exam. Additionally, it can also be used in small consumer electronics, such as fitness trackers and smart watches, to measure body temperature.

Working Principle

The GL122E5J thermistor operates on the principle of resistance changing in accordance with the temperature. In other words, the resistance of the thermistor changes in proportion to changes in temperature; the greater the temperature, the greater the resistance. This is why thermistors can be used for temperature sensing, as the change in resistance can be used to determine a temperature change.

The majority of thermistors operate using a standard resistor referred to as a PTC (Positive Temperature Coefficient) or NTC (Negative Temperature Coefficient). The GL122E5J thermistor is an NTC thermistor; this means that as the temperature increases, the resistance decreases. This characteristic is due to the unique materials used in the thermistor construction, such as metal oxides, which are known for their ability to change resistance based on temperature.

Conclusion

The GL122E5J thermistor is a type of NTC thermistor which can be used for various temperature sensing and detection applications. This includes uses in home appliances, consumer electronics, automotive, medical and industrial applications. The device operates on the principle of resistance changing in accordance with the temperature, with the resistance decreasing as the temperature increases. Ultimately, the GL122E5J thermistor is a useful and highly accurate device which has a variety of uses in temperature sensing and detection applications.
