Pressure sensor

- Working principle: Based on the piezoresistive effect, when the pressure in the hydraulic system changes, the resistance value inside the sensor will change accordingly. The pressure is determined by measuring the resistance change, and the pressure signal is converted into an electrical signal for output.
- Function: Real-time monitoring of the working pressure of the hydraulic system allows the excavator to "sense" its own status, so that the control system can adjust the actions of each part according to the pressure data to ensure the safety and stability of the operation.
- Application: Widely used in various hydraulic circuits of excavators, including main pumps, travel motors and working devices, etc., to help operators control the equipment status, optimize energy consumption management, and improve operational safety.

Speed ​​sensor

- Working principle: Generally, it is a magnetic pulse type. By detecting the rotation of components such as the crankshaft or camshaft, a weak electrical signal is generated, and its frequency is proportional to the speed, so as to detect the speed of the engine or other rotating parts.
- Function: Feedback the engine speed signal to the control system of the excavator, so that the control system can judge the working state of the engine according to the speed information, and then control the engine and hydraulic system.
- Use: Used for engine speed control, injection timing adjustment and hydraulic system power matching, etc., to ensure that the engine can maintain good performance and fuel economy under different working conditions.
