<p>Title: DIFFERENTIAL PRESSURE TRANSDUCER WITH HIGH COMPLIANCE, CONSTANT STRESS CANTILEVER BEAM Inventor: Gurnam Singh In a differential pressure transducer, of the type having a cantilever beam mechanically linked to a pressure-sensitive diaphragm, and piezoelectric strain gauges diffused into or bonded onto the beam, the beam has a relatively high compliance as compared with the diaphragm to facilitate operation in low pressure ranges and to increase the overall operating range of the unit. In addition, the beam is constructed so that the total bending energy is transmitted to the area of the strain gauges so as to achieve near-perfect operating efficiencies.</p> |
