ABSTRACT:
A pressure transducer is shown having a pressure responsive movable diaphragm which effectively forms a wall of a pressure chamber; the diaphragm upon sensing fluid pressure thereagainst is effective for accordingly varying an electrical resistance; a passage operatively interconnects the pressure chamber with a source of fluid whereby the fluid and its pressure are communicated to the pressure chamber; the passage is shown as being helically formed in order to, within a limited axial length about which the helical passage is formed, sufficiently damp perturbations in the pressure of the fluid.
