Abstract
PURPOSE: To enable the failure of measuring diaphragm to be detected in the state of being mounted to plant by providing a device of detecting the failure of the measuring diaphragms to the primary sealing liquid side of the diaphragms which receive measuring pressure.
CONSTITUTION: The measuring pressure P of the high temperature metal fluid 1 passing the inside of piping 2 is transmitted to a pressure transmitter 13 by way of the diaphragm 5 of a vessel 4, the sealing liquid 7 in a capillary tube 8, the diaphragm 10 in a vessel 9 and secondary sealing liquid 11. To detect the failure of the measuring diaphragm 6 in the state where the measuring pressure P in being applied to the plant side, a valve 14 is opened to apply the pressure higher than the measuring pressure P, then if the measuring diaphragm 6 has not caused failure, the pressure corresponding to the pressure applied is sensed in the pressure transmitter 13 but if the diaphragm 6 has caused failure, the pressure sensed in the pressure transmitter 13 does no longer coincide with the pressure applied.
