Abstract

PURPOSE: To easily perform the calibration of zero point and measured pressure an to check the diaphragm,, by providing the calibration means on the way of the second pressure transmission medium pipe way.
CONSTITUTION: The calibration means 27 is constituted by providing the first valve 17 on the way of capillary tube 15, pressure guide tube 18 between the first valve 17 and the pressure transmitter 14, diaphragm, and the calibration pressure guide section 20 sealing the secondary pressure transmission medium 16 such as silicone oil. After the pressure Pb almost equal to the plant pressure Pa from the pressure reception inlet 22 of the calibration pressure guide section 20, and when the second valve 19 is opened and the first valve 17 is closed, the plant pressure Pa is interrupted. When the pressure Pb is zeroed, no pressure is exerted to the pressure transmitters 14 to enable zero point calibration. A pressure higher than the plant pressure Pa is fed from the pressure reception inlet 22 and after leaving for several minutes with the first valve 17 opened, the first valve 17 is closed to zero the pressure and the zero point is measured. The pressure reception diaphgram 3 and the replacement 9 can be changed with the comparison between the both zero point measurements.
