Claim:
1. An ultrasonic transducer device comprising: a body; an ultrasonic transducer mounted onto the body to have a single mechanical load bearing interface (“single interface”) with the body; wherein the ultrasonic transducer comprises a shoulder corresponding to the single interface, a diaphragm and a piezoelectric element disposed on a sensor, wherein the diaphragm emits a sonic or ultrasonic acoustic wave when excited; an O-ring placed on the shoulder; wherein the O-ring substantially covers the single interface between the ultrasonic transducer and the body; wherein the O-ring comprises a gasket that provides an acoustic impedance mismatch between a housing of the ultrasonic transducer and the body so that acoustic energy is reflected at an interface between the ultrasonic transducer and the body; and an oil compensation system to adjust a pressure bearing on the O-ring, wherein the oil compensation system provides a constant mechanical load which permits the O-ring to maintain the acoustic impedance mismatch provided by the O-ring.
