A temperature sensor is a widely used sensor whose characteristic is that the higher the temperature, the smaller the resistance value. The working principle of a temperature sensor is based on the temperature-sensitive property of semiconductor materials. When the temperature rises, the resistance value of the semiconductor material decreases. The junction temperature, also known as the limit temperature or maximum temperature, refers to the highest temperature that a temperature sensor can withstand under normal working conditions. The junction temperature is an important indicator for evaluating the performance of a temperature sensor, as it directly affects the reliability and stability of the sensor. The junction temperature of a temperature sensor is generally tested and calibrated by the manufacturer during the production process and marked in the product specification sheet. When selecting and using a temperature sensor, it is essential to ensure that the measured temperature does not exceed the sensor's junction temperature, otherwise it may lead to sensor failure or damage. In practical applications, the junction temperature of a temperature sensor depends on multiple factors such as the thermal conductivity of the material, insulation performance, and packaging method. To increase the junction temperature of a temperature sensor, manufacturers usually adopt high-quality materials, reasonable packaging designs, and advanced manufacturing techniques. In some high-temperature environments, such as automotive engines and electric motors in industrial fields, high-junction-temperature temperature sensors are required. These sensors typically use ceramic or metal packaging and can operate stably in high-temperature environments. Additionally, measures such as using heat insulation materials and heat dissipation devices can be taken to increase the junction temperature of the sensor. For general household electronic devices and industrial control systems, the junction temperature of a temperature sensor is usually around 100°C. Within this temperature range, a temperature sensor can meet most temperature measurement requirements. However, in some special applications, such as high-temperature furnaces and heat treatment equipment, temperature sensors with higher junction temperatures are needed.
