Abstract
A pressure transducer with a diaphragm coupler at one end and a sensing element at the other end connected by a capillary tube. The sensing element includes a cap member having a deformable surface including a top wall forming a thin diaphragm having a diametrically disposed raised beam extending across the top surface and having a gage received surface for receiving a plurality of strain gages. The deformable top wall surface has indentations therein on either side of and extending longtudinally of the raised beam to reduce tension forces across the diaphragm and improve linearity of the diaphragm.
