Pipeline fluid pressure fluctuation sensing device

Abstract

A pipeline fluid pressure fluctuation sensing device includes a housing, vibrating membrane, fixing ring, pressure balance hole, magnetic element, and magnetic sensing element. The housing includes an open end and closed end opposite to each other, so that no conducting wire is passed through the housing; the open end is used to connect the fluid pipeline. The vibrating membrane is provided inside the housing, and the vibrating membrane is allowed to be displaced due to the pressure change generated from fluid pipeline. The fixing ring is connected between the housing and vibrating membrane. The pressure balance hole is passed through the fixing ring and used to balance pressure at the two opposite sides of the vibrating membrane. The magnetic element and vibrating membrane are linked to each other, where the magnetic element is generated with a displacement change due to the displacement of the vibrating membrane.
