Zusammenfassung: | A pressure detecting device is mounted in a measurement target and instrument includes a strain inducer to which pressure of a pressure medium is applied and which generates strain in accordance with the pressure and a strain detecting element that is bonded onto a surface opposite to a pressure receiving surface of the strain inducer, in which the strain detecting element includes one or multiple central strain resistant bridges which are arranged at a central portion of the strain detecting element in a bonded surface direction, and one or multiple outer peripheral strain resistant bridges which are arranged at an outer periphery, and in which, for example, deformation of the strain detecting element caused by an external force when being screw-fixed to the measurement target instrument is obtained through the multiple strain resistant bridges. An error of detection pressure caused by the deformation in a pressure value detected through the central strain resistant bridge is corrected. |
