The temperature sensor is used to monitor the temperature of the exhaust gas in the exhaust pipe of the car. By accurately measuring the exhaust gas temperature, it can provide key data for the engine management system, thereby achieving precise control of the engine operating status.
Its working principle is to use precision thermocouple or thermistor technology to detect temperature changes. When the temperature changes, the resistance value or potential difference of these elements will change, thus generating a temperature-related signal.
