Means and method of sensing pressure using magnetostrictive electrical conductors

摘要

In one embodiment, a sensor assembly has a sensor housing (17, 38) forming a fluid chamber and a magnetostrictive wire (18, 23, 30) that undergoes stress induced by fluid in the chamber. The wire (18, 23, 30) defines opposed ends, each being associated with a respective terminal. Respective hermetic seals (20) penetrate the housing (17, 38) and are coupled to the respective terminals.
