Title: Sture Siby: Innovator in Pressure Measurement Technologies
Introduction
Sture Siby is a notable inventor based in Vasteras, Sweden. He has made significant contributions to the field of pressure measurement technologies, holding a total of 6 patents. His innovative designs have advanced the functionality and accuracy of load cells and pressure-sensing transducers.
Latest Patents
One of Siby's latest patents is a pressure-compensating device in load cells. This invention addresses the challenge of compensating for external and internal pressure variations in hermetically closed load cells. The device utilizes three parallel diaphragms that are vacuum-tightly attached between a force-transmitting member and a surrounding housing. The internal diaphragm is positioned adjacent to the transducer space, while an equally sized external diaphragm is located adjacent to atmospheric pressure. An intermediate diaphragm, which is considerably larger than the other two, is situated between them. This configuration allows for an equilibrium of forces to be achieved, independent of pressure variations.
Another significant patent is a pressure-sensing transducer designed for continuous pressure measurement in the cylinder of an internal combustion engine. This transducer features a pressure-transmitting element with a generally tubular seat and a metallic plate that closes off the top end of the seat. An M-shaped force-transmitting member spans across the top end, with its outer legs connected to opposite portions of the seat and inner legs connected to the center of the metallic plate. A magnetoelastic force-sensing member is connected between the outer legs, transforming pressure-generated forces into a tensile force acting on the force-sensing member.
