ABSTRACT:
A method for making a pressure transducer comprising: forming a recess in a diaphragm, the diaphragm having a thinned region that deflects responsively to pressure being applied thereto; depositing a glass frit in the recess; embedding a plurality of strain gages in the glass frit; and, wire bonding the strain gages into a Wheatstone bridge configuration.
