Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
High pressure transducer to be mounted in either a first or second distinct type of mounting hole in a component comprising: a transducer body; a sensor means mounted to said transducer body; a diaphragm means mounted to said sensor means and transducer body; first means integral to said transducer body for forming a shoulder seal only with a first type of mounting hole; and second means integral to said transducer body for forming a seal at a front end of said transducer body only with a second type of mounting hole.
Claim 2
Dependent Claim
91 words
High pressure transducer to be mounted in either a first or second distinct type of mounting hole in a component comprising: a transducer body; a sensor means mounted to said transducer body; a diaphragm means mounted to said sensor means and transducer body; first means integral to said transducer body for forming a shoulder seal only with a first type of mounting hole; and second means integral to said transducer body for forming a seal at a front end of said transducer body only with a second type of mounting hole.
Claim 3
Dependent Claim
50 words
High pressure transducer according to claim 1, wherein said first means includes an intermediate section between the axial ends of said transducer body of an enlarged radial diameter to form a shoulder sealing surface which can be sealed against a shoulder offset surface of a first type of mounting hole.
Claim 4
Dependent Claim
33 words
High pressure transducer according to claim 2, wherein said sensor means is mounted to said transducer body by third means providing an annular gap therebetween for isolating said sensor means from sealing forces.
Claim 5
Dependent Claim
33 words
High pressure transducer according to claim 2, wherein said second means includes a tubular extension with a sealing surface which can be sealed against an offset surface of a second type mounting hole
Claim 6
Dependent Claim
28 words
High pressure transducer according to claim 4, wherein said sensor means is mounted to said transducer body by elastic means for isolating said sensor means from sealing forces.
Claim 7
Dependent Claim
31 words
High pressure transducer according to claim 2, wherein said intermediate section forms a retainer surface which can receive an externally threaded retainer which mounts said transducer body to a mounting hole.
Claim 8
Dependent Claim
33 words
High pressure transducer according to claim 2, wherein said transducer body includes a thread section between said intermediate section and said front end which can mount said transducer body to a mounting hole.
Claim 9
Dependent Claim
33 words
High pressure transducer according to claim 1, wherein said sensor means is mounted to said transducer body by third means providing an annular gap therebetween for isolating said sensor means from sealing forces.
Claim 10
Dependent Claim
33 words
High pressure transducer according to claim 1, wherein said second means includes a tubular extension with a sealing surface which can be sealed against an offset surface of a second type mounting hole.
Claim 11
Dependent Claim
28 words
High Pressure transducer according to claim 1, wherein said sensor means is mounted to said transducer body by elastic means for isolating said sensor means from sealing forces.
Claim 12
Dependent Claim
19 words
High pressure transducer according to claim 1, wherein said diaphragm is adjacent said front end of said transducer housing.
Claim 13
Dependent Claim
23 words
High pressure transducer according to claim 1, wherein said transducer body includes a threaded section which mounts said transducer to a mounting hole.
Claim 14
Dependent Claim
18 words
High pressure transducer according to claim 12, wherein said threaded section is between said first and second means.
