Patent ID: 8800373

Claim:
A transducer assembly for diagnosing acoustic noise from a pressure vessel, comprising: an acoustic sensor element; an acoustic waveguide including a rotatable acoustic coupler coupled to the acoustic sensor element, a tube having a first tube end coupled to the rotatable acoustic coupler and a second tube end coupled to a foot portion which extends parallel with a sealed fluid conduit acoustically couplable to the sealed fluid conduit, wherein the foot portion extends parallel with the sealed fluid conduit along an exterior of the sealed fluid conduit; and a temperature sensor in the foot portion configured to sense a temperature of the conduit; a circuit assembly coupled to the acoustic sensor element and the temperature sensor, the circuit providing a diagnostic output responsive to an acoustic vibration delivered to the acoustic sensor element through the rotatable acoustic coupler and a temperature output from the temperature sensor, wherein the circuit assembly is rotatable about the rotatable acoustic coupler with respect to the foot portion.
