Abstract
An improved pressure transducer and method of making the transducer is disclosed. Generally, the transducer is made from sheet materials and is designed to incorporate the advantages of both the beam-type and diffused diaphragm type transducer while reducing or eliminating many of the disadvantages. The product is designed so that multiple units can be provided from a single multi-sheet composite with a relatively high reproducibility at relatively low cost.
