ABSTRACT:
A pipe pressure sensor (10) comprises a chamber holder (14) for defining a hollow chamber (28) which is urged toward a pipe (20) to clamp a diaphragm (16) between the pipe and a portion of the chamber holder surrounding a pressure-inlet opening (30) into the chamber. The diaphragm has a round, sensing, protrusion (42) with a sensing tip (46) on an outer end thereof for extending outwardly from one side of the diaphragm to extend through a round hole (44) in the pipe so as to communicate pressure in the pipe to the chamber.
