ABSTRACT:
A low cost pressure transducer can be manufactured and assembled with automatic or semiautomatic production line techniques. The transducer includes a pressure fitting, a diaphragm, a strain gage comprising a bridge circuit and tabs with leads for the bridge circuit, and a termination board, all contained within a case. One end of the case is swaged over a flange on the fitting in order to sealingly clamp the diaphragm between a shoulder in the case and the fitting flange. The bridge portion of the strain gage is adhesively secured to the diaphragm. A pressure distribution member is placed over the bridge so pressure may be applied to the assembly during heat-curing of the adhesive which secures the gage to the diaphragm. The termination board has four terminals and a corresponding number of conductive strips. It is positioned in the case so that each of the conductive strips is pressed into electrical contact with a corresponding lead on the tabs of the gage. The other end of the case is swaged over the termination board to lock the latter in place.
