The temperature sensor measures the temperature through a platinum thermistor installed in the probe tube. When the temperature changes, the platinum resistor outputs a resistance signal that changes with temperature through the connector. Through the characteristic of the platinum thermistor changing resistance value with temperature within the temperature range, the resistance signal at the measurement position is fed back to the corresponding system module for processing, converted into a temperature signal, and real-time monitoring of temperature changes at the testing position ensures the safety of train operation.
The sensor has strong weather resistance, high protection performance, excellent impact resistance and vibration resistance, good electromagnetic compatibility, strong anti-interference ability, fast and accurate temperature measurement, stable signal transmission, multi-point detection, centralized transmission, and convenient installation. Sensors have the characteristics of high accuracy, good linearity, stable electrical performance, reliable operation, and long service life. The technical performance indicators comply with a series of standards such as IEC60751 and GB/T30121.

Matters needing attention
1. During installation, sensors and electrical connectors should be well protected, and it is strictly prohibited to fall or collide;
2. After the installation and connection of the sensor are completed, the wiring should be checked for correctness and confirmed before power can be transmitted to avoid damage caused by strong electricity mistakenly connecting to the sensor;
3. When the storage period of the sensor exceeds 1 year, the temperature resistance value and insulation resistance value of the sensor should be tested before installation to ensure good sensor performance;
4. The scrapped sensors should be properly disposed of to avoid any impact on the environment.
