Latest Patents

One of his latest patents is a method for producing a vacuum measuring cell of the membrane type. This invention involves a pressure transducer diaphragm with housing plates sealed on opposite sides to form reference and measuring vacuum chambers. An opening in one plate communicates with the measuring vacuum chamber and has a sealed connection for joining to the medium to be measured. The diaphragm and plates are made of aluminum oxide ceramic, and at least one of the seals is aluminum with a thickness ranging from 0.5 μm to 30 μm. The ceramic parts are pressed together at an increased temperature of 600°C to 680°C in a process gas atmosphere that includes a reducing gas, followed by a tempering step in a second process gas atmosphere that includes oxygen, at a temperature of 450°C to 575°C, allowing the metallic aluminum to oxidize into aluminum oxide.

Another significant patent is for an optical interferometric pressure sensor. This pressure measuring cell features a first housing body and a membrane arranged proximate to the housing body, both made of ceramic. The membrane has a peripheral edge joined to the first housing body, creating a reference pressure chamber. A second housing body made of ceramic material is positioned opposite the membrane and is joined to the peripheral edge of the membrane, forming a measurement pressure chamber. The second housing body includes a port for connecting the pressure measuring cell to the medium to be measured. The design ensures that the first housing body, the second housing body, and the membrane are tightly connected along the peripheral edge of the membrane, with a central hole formed in the first housing body that allows for optical measurement.
