Title: Fluid vibration detector sensor and fluidic flow meter using it
Inventor: NUKUI KAZUMITSU
IPC: G01H11/02
Filed: 1994-12-09
Abstract: PURPOSE: To prevent erroneous detection of fluid vibration due to corrosion of electrodes by eliminating metal electrodes from a part (a vibration film) which is most deformed by fluid vibration. CONSTITUTION: A piezoelectric element 40A and a piezoelectric element 40B are installed and fixed in a pressure chamber 33A of a pressure fluctuation detecting part 33 and in a pressure chamber 33B of a the pressure fluctuation detecting part 33, respectively, near vibration films 35. Each vibration film 35 vibrates due to pressure difference fluctuation between the pressure chambers 33A, 33B and pressure difference fluctuation between the pressure chambers 34A, 34B. Corresponding to the vibration of the vibration film 35, the center part 35b of the vibration film 35 comes into collision against respective piezoelectric elements 40A, 40B and applies pressure. The pressure is converted into an electric signal corresponding to the fluid vibration by the piezoelectric elements 40A, 40B and outputted.
