Abstract:
A pressure sensor, comprising:a first cylindrical metal member having a closed top surface and an opened bottom surface, said closed top surface having a central boss extending towards said open bottom surface, a second cylindrical metal member having an inner recess surrounded by a flange, with the outer surface of said second cylindrical member secured to the periphery about said open bottom surface of said first cylindrical member, a leadless semiconductor sensor having a central boss surrounded by an active deflecting region to enable said sensor to produce an output when a pressure is applied to said semiconductor sensor boss, said sensor positioned on an insulator support member and located in said inner recess of said second cylindrical member with said support member positioned on said flange, with said central boss of said sensor in contact with said central boss of said first cylindrical member to cause a force applied to the closed top surface of said first cylindrical member to be applied to said sensor via said associated bosses.
