Heavy Truck water temperature gauge sensor DZ9100580052 for SHACMAN Cummins Engine Parts

Functions of water temperature gauge sensor DZ9100580052

Water temperature monitoring and display: Its core function is to monitor the water temperature in the cooling system of heavy truck engines in real time, and accurately convert the water temperature information into electrical signals, and then transmit it to the water temperature gauge on the vehicle dashboard, so that the driver can intuitively understand the operating temperature of the engine. During normal operation, the water temperature gauge will accurately indicate the high and low engine water temperature based on the signal from the sensor, helping the driver to detect abnormal water temperature in time.
Assisted engine control: In addition to providing signals to the water temperature gauge, the sensor may also send water temperature signals to the engine control unit (ECU). The engine control unit will adjust some operating parameters of the engine according to the water temperature information, such as the injection amount, ignition advance angle, etc., to ensure that the engine can maintain good performance and fuel economy under different water temperature conditions, and also help protect the engine from adverse working conditions such as overheating or overcooling.

Working principle of water temperature gauge sensor DZ9100580052

Heavy truck water temperature gauge sensor DZ9100580052 usually adopts the thermistor working principle. The internal thermistor has a negative temperature coefficient, that is, the lower the temperature, the greater the resistance value; the higher the temperature, the smaller the resistance value. When the engine cooling water temperature changes, the resistance value of the thermistor in the sensor also changes, causing the current passing through the sensor to change. The water temperature gauge displays the corresponding water temperature scale according to the size of the current, thereby realizing the measurement and display function of the water temperature.
