Title: Pressure difference measuring device
Inventor: NISHIHARA TADASHI
IPC: G01L13/02
Filed: 1981-11-06
Abstract: PURPOSE:To reduce span errors in static pressure, tightening and temperatures, by providing bellows which are displaced by the pressure difference in the housing, and obtaining the displacement of the bellows from the change in electric capacity between a movable electrode and fixed electrodes. CONSTITUTION:The bellows 11 which are displaced by the pressure difference is provided in the housing 2. A plate shaped movable electrode 12 is attached to the free end. The fixing electrodes 16 and 17 are provided in a ring shape so as to face the electrode 12. When high pressure is introduced in a measuring chamber 61 and low pressure is introduced in a measuring chamber 71, sealed liquid 4 and 5 is transmitted through diaphragms 23 and 24, the bellows are moved to the right, the electric capacity between the electrodes is changed, and the pressure difference is measured highly accurately. In this constitution, even though the housing 2 is distored in the radial direction by the large static pressure, the distortion is absorbed by bellows ends, and the span errors due to the static pressure and tightening are hard to occur. Even though the material of the housing 2 is different from the material of the bellows 11, the deformation of the housing due to the temperature is not transmitted to the bellows 11, and the cause of the span errors due to the temperature is eliminated.
