Hydraulic jack control unit

Hydraulic jack control unit

This device is used for load/displacement control and holding control of hydraulic jacks, and can control 2 or 4 systems. The amplifier can be controlled by a personal computer for auto-zero, range setting, calibration, etc. The detected load and displacement can be calculated by the PC as a sum of two points, averaged, etc., to control the load and displacement of the jack as desired.
