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.

A pressure sensor to be mounted on a pipe having a hole therein for measuring the pressure of fluid in the pipe comprising: a chamber holder for defining a hollow chamber having a pressure inlet opening and a pressure outlet opening; a pressure gauge attached to said chamber holder and communicating with said hollow chamber through said pressure outlet for measuring the pressure of a fluid in said hollow chamber; a fluid in said chamber; a mounting means for engaging a pipe and said chamber holder and mounting said chamber holder on said pipe by urging the pressure-inlet opening of said chamber holder toward said pipe; a diaphragm comprising a wide flat flange means and a narrower, round, sensing protrusion with a sensing tip on the outer end thereof extending outwardly from one side of the diaphragm, said flange means having the function of being positioned between said chamber holder and an outer surface of said pipe to form a sealed interface between a portion of said chamber holder surrounding said pressure-inlet opening and said pipe, said protrusion extending through said hole in said pipe so as to communicate pressure of fluid in the pipe to the fluid in the chamber via the diaphragm, said sensing protrusion having a length such that when the pressure sensor is mounted on said pipe the sensing tip of said sensing protrusion is positioned approximately at an inner surface of said pipe and a diameter which is approximately the same as the diameter of said hole; whereby a hole can be bored in said pipe having a diameter of approximately the diameter of said round sensing protrusion, said pressure sensor can be mounted at said hole with said sensing protrusion extending therethrough so that pressure of fluid in said pipe is transmitted to said pressure gauge via said sensing protrusion.
