Latest Patents

Duplain holds a patent for a diaphragm pressure measuring cell arrangement. This invention features a housing body that is partially made of sapphire material. It includes a planar sapphire diaphragm with a peripheral edge that is joined by a first edge seal to the housing body, forming a reference vacuum chamber. The outer surface of the diaphragm is exposed to the medium that is to be measured. A ceramic supporting body is attached to the back side of the housing body using sealing glass, which includes a surface area that overhangs and surrounds the housing body to create a first sealing surface. Additionally, a tubular sensor casing incorporates the measuring cell for mounting the ceramic support body. The casing features an inside second surrounding sealing surface that corresponds to the first sealing surface. A metal ring seal is positioned between the sealing surfaces, and a pressing member ensures that the sealing surfaces are pressed together. This innovative design enhances the accuracy and reliability of pressure measurements.
