Abstract
A narrow pressure sensor unit interposable between close spaced flanges on coaxially opposed pipes. The pressure sensor unit includes an annular body sandwiched coaxially between two flanking rings of lesser inside diameter by a circumferential array of axial fasteners. A resilient cylinder has an intermediate portion spaced radially inward of the annular body by an annular sensing fluid chamber. The cylinder is of generally U-shaped cross section and has sides extending radially outward along annular reliefs in the flanking disks. Axially widened lips on such sides lie in opposed annular grooves in the flanking rings, and are compressed between the axially opposed surfaces of the respective flanking ring groove and body to seal the fluid chamber. The lips are radially wider than the axial width of the reliefs to lock the lips in the grooves. A pressure gauge connects through the body to the sensing fluid chamber.
