ABSTRACT:
A hydraulic pressure cylinder incorporating a double-rod type piston, for example an injection cylinder has a pair of pressure sensors for detecting the hydraulic pressures of fore and rear oil chambers. are respectively detected by a pair of pressure sensors 4, A detected pressure value Pd is subsequently obtained from the difference between respective oil chamber pressure measurements Pdf, Pdr based on the outputs respectively from pressure sensors. The detected pressure value Pd of period Ts during which detected pressure value Pd becomes zero theoretically, is calculated in advance. The calculated detected pressure value Pd is stored as correction value A. At the time of pressure sensing, the detected pressure value Pd is corrected according to correction value A, whereby the accurate zero adjustment point may always be maintained without being influenced by a temperature drift, enabling an accurate and high-precision pressure sensing.
