ABSTRACT:
A differential pressure sensor (10) having a housing 12 and a metal or alloy isolator (14) for stress isolation of a sensing cell (28) that is mounted to the isolator (14). The metal or alloy isolator (14) has an opening (16) therein for providing access to the sensing cell (28). The housing (12) is molded around the isolator (14) creating a seal therebetween and isolating the sensing cell (28).
