KHR10290/KHR41950 KHJ18180/KHJ11380 Original SENSOR;PRESS/ Joint SH210-5/350-5/450-5 SUMITOMO Excavator Electric Parts
The high pressure sensor is mounted on the excavator hydraulic pump shell,
The working principle is that the pressure of the measured pressure directly ACTS on the sensor's sensor plate, causing the sensor plate to produce a micro displacement proportional to the pressure, causing the sensor resistance value to change, and the electronic circuit to detect this change, and convert to output a standard measurement signal corresponding to the pressure.
The high pressure sensor measures the pressure at the main pump outlet (also the system pressure) as the input signal for control. Electric control excavator to power control, prevent engine overload, or power overshoot.
The flow can be actively controlled by rotating speed and displacement
