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.
