力発信器の基準圧力室密封構造。 An absolute pressure transmitter comprising a reference pressure chamber that faces a reference side pressure measuring chamber containing a pressure transmission medium via a barrier diaphragm and is maintained at a constant reference pressure state, in a state in which the absolute pressure transmitter is communicated with the reference pressure chamber. A pair of pipes that protrude outside the transmitter to introduce a reference pressure to set the interior pressure to the reference pressure, and a presser that pinches the middle of this pipe from both sides in the radial direction to compress and deform it to seal the passage inside the pipe. 1. A reference pressure chamber sealing structure for an absolute pressure transmitter, comprising: a tightening member; and a sealing member consisting of a plurality of screw members that connect and fix the tightening members in close proximity to each other.
