First Claim
Patent Images
1. A transducer assembly for diagnosing acoustic noise from a pressure vessel, comprising:
- an acoustic sensor element;
an acoustic waveguide that comprises a acoustic coupler coupled to the acoustic sensor element, a tube that has a first tube end coupled to the acoustic coupler, and a second tube end acoustically couplable to a fluid conduit; and
a circuit assembly coupled to the acoustic sensor element, the circuit providing a diagnostic output.
