ABSTRACT:
A high pressure transducer includes a first disk member having positioned on a surface, a square piezoresistive bridge array. Located above and coaxial with the first disk member is a second member of a substantially greater thickness. The second member has a plurality of apertures in alignment with the terminal areas contained within said bridge pattern. The apertures accommodate leads which are directed from the bridge pattern on the first disk to utilization means for monitoring transverse variations in the bridge when operating in a high pressure environment.
