Abstract
A differential pressure sensor comprises a pressure-to-displacement transducer resiliently coupled to a cantilever beam strain gauge arrangement. The pressure-to-displacement transducer is provided with overrange protection permitting substantial displacement in the range of measurable pressure differentials and the more fragile cantilever beam is provided with separate overrange protection more narrowly constraining its displacement. The resilient coupling between the transducer and the beam absorbs the displacement differential. As a consequence of this structure, the device can provide high sensitivity readings in the measurable range of pressure differentials and is protected against pressure differentials greatly in excess of the measurable range.
