Abstract

PURPOSE:To improve accuracy, by bonding the sealed end of a diaphragm to the upper surface of a photoelastic element, and bonding the other open end of the diaphragm to a case, which is sealed in an airtight manner. CONSTITUTION:The bottom of a diaphragm is bonded to the pressure receiving surface of a photoelastic element 5. A case 11 of a pressure sensor part is strictly sealed in an airtight manner so the internal pressure always becomes one atm. In this case, the sealed end of the diaphragm 6 is bonded to the upper surface of the photoelastic element 5, and the other open end of the diaphragm is bonded to the case, which is sealed in the airtight manner. In this constitution, the pressure is efficiently applied to the photoelastic element and high accuracy is obtained.
