Abstract
A system, method, and apparatus for reducing ringing effects associated with a transducer comprises a transducer body, a transducer cap, a piezoelectric element formed in the cap, and a damping material formed around the piezoelectric element wherein the damping material suppresses a ringing effect associated with the transducer, while an O-ring is used together with damping material to support high pressure applications up to 230 bars.
Claims20
A transducer apparatus, comprising:
- a transducer comprising a transducer body and a transducer cap;
- a piezoelectric element formed in said transducer cap;
- a damping material and an O-ring formed around said piezoelectric element, wherein said damping material suppresses a ringing effect associated with said transducer;
- and
- a potting material configured in said transducer body, wherein said potting material is separated from said piezoelectric element by said damping material.
A transducer system, comprising:
- a transducer body;
- a transducer cap;
- a piezoelectric element formed in said cap;
- an O-ring formed between said transducer body and said transducer cap;
- a damping material comprising an adhesive silicone sealant and heat-sink compound formed around said piezoelectric element, wherein said damping material suppresses a ringing effect associated with said transducer;
- and
- a potting material configured in said transducer body, wherein said potting material is separated from said piezoelectric element by said damping material.
The transducer system of claim, 12 wherein said O-ring is formed of a material comprising at least one of:
- rubber;
- silicone;
- and
- fluorine rubber Nitrile-butadiene (NBR).
A transducer, comprising:
- a piezoelectric element formed in a transducer cap;
- a transducer body wherein a mouth of said transducer body has a diameter of at least 50% of a diameter of said piezoelectric element comprising a disc;
- an O-ring formed between said transducer body and said transducer cap;
- a damping material comprising an adhesive silicone sealant and heat-sink compound formed around said piezoelectric element, wherein said damping material suppresses a ringing effect associated with said transducer;
- and
- a potting material configured in said transducer body, wherein said potting material is separated from said piezoelectric element by said damping material.
