A non-invasive pressure measurement device measures pressure of fluid in a conduit via a piezoelectric transducer positioned proximate to the conduit having a fluid passing therethrough. The piezoelectric transducer is in communication with the conduit via a plate member having a protrusion extending outward from one side of the member. In one application, the device continuously measures blood pressure without the need for an inflatable cuff. Also, the device can detect and measure heart beat pulses from the fluid and utilize heart beat pulse information to provide further characteristics pertaining to the fluid in the conduit.
