Abstract
An electric transducer has a casing with a plurality of walls defining a pair of chambers, and one of the walls interposed between the chambers defines a diaphragm for deflection in response to fluid pressure in one of the chambers. A strain gauge disposed on the one wall in the other of the chambers spans the diaphragm for conjoint deflection therewith to establish an output voltage correlative with the diaphragm deflection, and an electronic amplifier in the other chamber is connected in circuit relation with the strain gauge for amplifying the output voltage.
