Title: Grant B Edwards: Innovator in Level Measurement Technology
Introduction
Grant B Edwards is a notable inventor based in Blaine, MN (US). He has made significant contributions to the field of level measurement technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Microwave Level Gauge with Remote Transducer." This invention is a level sensor designed for process applications that measures the height of a product in a tank. The level meter features a microwave feedhorn directed into the tank, an electronics housing spaced apart from the feedhorn, and a microwave waveguide extending between them. A microwave transducer in the housing couples to the waveguide, sending and receiving microwave signals. A microprocessor identifies echoes from these signals, determining the height of the product based on microwave echoes from both the product and the feedhorn. The microprocessor also compensates for propagation delay through the waveguide, providing accurate height measurements.
Another significant patent is the "Barrier Device." This device threadably mounts to a cabling aperture on a field-mounted transmitter, which receives and transmits signals powered by a current loop circuit. The barrier device has a conductive housing with multiple apertures and conductors for connecting to a terminal block in the transmitter. It includes signal terminals that connect to a handheld communicator for calibration, monitoring, and testing of the transmitter. The barrier circuit limits the power available at the signal terminals, ensuring safe operation.
