PURPOSE:To prevent distortion from being transferred to a distortion generating cylinder, by providing a ring-like slit on a pressure receiving plate, dividing the pressure receiving plate into the inside and outside parts, connecting these parts by a flexible member, and fixing the lower end part of the distortion generating cylinder to the inside pressure receiving plate. CONSTITUTION:The pressure gauge in constituted so that a ring-like slit is provided on a pressure receiving plate 2, the pressure receiving plate 2 is divided into the inside and outside parts, also these parts are connected by a flexible member 2a, and the lower end part of a distortion generating cylinder 3 is fixed to the pressure receiving plate 2. As a result, clamping distortion of a cylindrical body 1 in case when the cylindrical body 1 has been installed to a body to be measured, by a fitting screw 1a, and distortion following the temperature deformation of the cylindrical body 1 which has been installed are absorbed by elastic deformation of the flexible member 2a. Also, these distortions are not transferred to the inside pressure receiving plate 2, and it is prevented that distortion is transferred to the distortion generating cylinder 3 through the pressure receiving plate 3 from the cylindrical body 1. |
