PURPOSE:To sharply improve a reliability of a detector through the check and correction of a pressure detection value during the operation of an installation, by a method wherein the detector is provided with a correcting means for correcting a detecting pressure, and a comparator for comparing a correction detecting pressure with a check pressure for the decision. CONSTITUTION:A pressure oil through a pressure detecting aperture 10 is pressure- detected through a conduit 118, a stop valve 119, and a branch pipe 121 by means of a pressure detector 8. A pressure signal from the detector 8 is corrected at a computing element 105 by the use of a constant from a correction constant generator 106 acting as a correcting means. This constitution permits the check and correction of a pressure detection value during the operation of an installation, and the appropriate replacement of a correction constant permits the sharp improvement of the reliability of a detector.
