Detailed Technical Description
The HJ-301011-3-A Electronic Shift Sensor Assembly is designed to detect the position of the intensifier piston and electronically signal the pilot shift valve to reverse hydraulic flow. This action allows the intensifier to cycle continuously, generating consistent water pressures that can exceed 60,000–90,000 PSI depending on system configuration.
Main Functions
- Detects piston end-of-stroke position.
- Initiates hydraulic shift valve actuation.
- Maintains continuous intensifier cycling.
- Enhances cutting accuracy and pressure stability.
- Reduces mechanical wear compared to older mechanical shifting systems.
- Supports reliable operation in demanding industrial environments.
The HJ-301011-3-A Electronic Shift Sensor Assembly is typically installed within the hydraulic drive section of H2O intensifier pumps and works together with the electronic pilot shift valve and proximity sensor system.
