Piezoresistive pressure-measuring element

摘要: A piezoresistive pressure-measuring element preferably comprises a cylindrical housing member (15), on the top side of end face which transmitting diaphragm (29) hermetically seals off pressure chamber (35) located thereunder. Located in is cell (1) resistors are provided. In order to provide can be used measure most varied, including aggressive, media conjunction with reductions costs material and production, as mass-produced article, it provided that (15) consist plastic, welded thermally by means ultrasound or dielectric heating onto above (Figure 1).
