ABSTRACT:
An improved invasive acoustic sensor apparatus detects particulate matter in a flow by impingement thereon. The apparatus includes an axially extending probe body having an active length positionable in a flow and a distributed piezoelectric transducer disposed therein. The transducer is acoustically coupled to an interior surface of the body, along substantially the entire active length thereof, and may be a piezoelectric film, piezoelectric tube, or a plurality of electrically parallel connected piezoelectric tube elements. The apparatus further includes an acoustic isolation layer disposed between the probe body and positioning structure to reduce transmission of process wall vibration to the transducer.
