ABSTRACT:
A differential pressure measuring device comprises a capsule including three correspondingly shaped side by side diaphragms secured to each other at their outer edges and encased in a capsule with the diaphragms surrounded by a potting compound which is placed in the capsule in a fluid condition and with pressure being applied to the capsule to hold the outer diaphragms in a limited position, the potting compound is allowed to harden or set.
