ABSTRACT:
A method of making a plurality of separate pressure transducers of the type comprising a strain gauge circuit bonded to a diaphragm, comprising the steps of providing an array of a plurality of strain gauge circuits formed on a laminate sheet and an array of a plurality of diaphragms corresponding to the array of the strain gauge circuits. The array of strain gauge circuits is aligned with the array of diaphragms. The laminate sheet is bonded to the array of diaphragms, with each strain gauge circuit aligned with a respective diaphragm. Finally, the laminate is cut to form the separate pressure transducers.
