Patent ID: 7284444

Claim:
A hermetically sealed displacement transducer, comprising: a load cell structure having a top surface and a bottom surface and having a thick outer peripheral area and a thick inner concentric central area with said outer peripheral area and said inner central area joined by two symmetrical thin beams directed along a common diameter with a first beam directed from an inner edge of said peripheral area to an outer edge of said central area, with a second beam directed along said diameter from an oppositely opposed inner edge of said peripheral area to an oppositely opposed outer edge of said inner area, said beams below the top surfaces of said peripheral and central areas and above the bottom surfaces thereof, at least a first strain gauge positioned on a surface of one beam, and at least a second strain gauge positioned on a corresponding surface of said second beam, a bottom cover member secured to said bottom surface of said peripheral area to cover and enclose said beams and said strain gauges, a top diaphragm cover member secured to said top surface of said peripheral area to cover and enclose said beams, with said cover member and said diaphragm member forming a hermetic cavity for said beams and strain gauges.
