PURPOSE: To measure the pressure of high-temperature caking gas without any deposition of gas by cooling by linking a branch pipe with a pressure transmission pipe inserted into a container whose internal pressure is to be measured and providing a seal pot which seals the opening end of the pressure transmission pipe with liquid.
CONSTITUTION: The pressure transmission pipe 12 is provided successively to the pressure reception part of a Bourdon-tube gauge 10 and a tank 14 are mounted by plural rods 16 atop of the pressure transmission pipe 12 so as to form a seal pot. Proper seal liquid 18 is put in this tank 14. A flange 26 is formed at the center part of the pressure transmission pipe 12 and fitted to a flange 24 provided to part 22 of the container. The branch pipe 20 is provided to the upper part of the pressure transmission tube 12 and inert gas is supplied from a supply cylinder to the branch pipe 20 through a control valve, passes in the seal liquid 18, and flows out gradually and continuously, the thereby measuring the pressure.
