Abstract

PURPOSE: To enable calibration of zero point and measuring pressure to be performed in the state of being mounted to plant by providing a means of isolating the pressure transmitter from measuring pressure.
CONSTITUTION: To calibrate zero point in the state where measuring pressure P is being applied to the plant side, a valve 3 is closed and a valve 13 is opened to make the pressure of a sealing gas take-out port 16 and the calibration of zero point may be performed. If a gas pressure is applied through the sealing gas take-out port 16 in this state, the pressure applied passes through the diaphragm 9 in a chamber 9 and is transmitted to secondary sealing liquid 10 and is thence transmitted to a pressure transmitter 12 by propagating in a capillary tube 11, hence calibration may be made at any point.
