Series-Hybrid Components Proportional Electro-Hydraulic Controls 656 . Furthermore, the closed-loop control design 3 4 1 2 5 High-accuracy, simple, convenient Series realizes your dreams. Highly accurate hydraulic control can be obtained only by supplying 24 V DC power and inputting a command signal voltage of 0 to 5 V . Why simple ? 3 4 The power amplifier and pressure sensor are integrated in the control valve. greatly improves the linearity, hysteresis and stability in control pressure. Why high-accuracy ? 1 2 Why convenient ? Analog voltages can be output by using the incorporated sensor for monitoring pressure, etc. Pressure can be displayed remotely with the indicators obtainable in the market and also can be transmitted into a computer. 5 If any trouble arises in the system and the command signal does not match to the output, the alarm signal is dispatched. The trouble, if arises, can be easily detected by monitoring the dispatch of the alarm signal with sequence controller or computer. 6 Power amplifier Details of Proportional Electro-hydraulic Relief Valve 1 Pressure sensor incorporated 2 Voltage output for pressure monitor 5 Command signal voltage input 4 24 V DC power supply 3 Alarm signal output 6 1. 2. 3. 4. 5. The sensor in directional control valves is to monitor the spool position. Valves without sensor are also available in both pressure control valves and directional control valves. Open-loop types are also available. EHDFG-04 and 06: 24V DC power supply is needed. EHDFG-01, 03, 04 and 06: 0 to 5V DC command signal is needed. EHDFG-04 and 06: The spool displacement is shown as a percentage.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
