繞した構成としたことを特徴とする圧力変換器。 In a pressure transducer that deforms a diaphragm using fluid as a pressure medium and detects the deformation of the diaphragm with a strain gauge to obtain an electric signal corresponding to the applied pressure, the inner peripheral wall is integrally or integrally connected to the peripheral edge of the diaphragm. A diaphragm support tube is formed to be sufficiently thicker than the diaphragm, and a conductive pin for deriving an electric signal from the strain gauge is inserted from one side of the terminal plate to the other side and fixed in an airtight state via an insulator. The airtight terminal or the airtight terminal holding plate integrally connected to the airtight terminal is formed to have strength to withstand ultra-high pressure exceeding the maximum limit pressure that would destroy the diaphragm, and the airtight terminal or the airtight terminal holding plate is A plate is firmly fixed to the end of the support cylinder by welding, and the back of the non-pressure receiving surface of the diaphragm to which the strain gauge is attached is connected to the support cylinder capable of withstanding the ultra-high pressure, and the airtight terminal or the airtight 1. A pressure transducer characterized in that the pressure transducer is surrounded by an airtight back with an appropriate space provided by a terminal holding plate.
