Abstract
A pressure sensing device includes a housing having an interior sized for containing a flexible diaphragm, the deflection of which causes subsequent movement of a movement mechanism relative to an indicating dial face. The diaphragm is nonfixedly attached to the bottom side of a support plate disposed within the housing interior, in which the plate includes a center opening sized to support the movement mechanism and position an input member of the movement mechanism adjacently to the flexible diaphragm. A pressure chamber is established between the bottom of the housing and the diaphragm such that air or other fluid entering the chamber causes deflection of the diaphragm and subsequent movement of the input member. Preferably, the diaphragm is retained within a slot formed in the housing and clamped into contact with a flexible gasket and the bottom surface of the support plate.
