Latest Patents
One of Andrews' latest patents is the "Media Independent Differential Pressure Transducer." This invention utilizes fluid-filled chambers as a pressure transfer linkage to an isolated, fluid-filled aneroid sensing system. The design features isolation diaphragms that are spread by internal fluid pressure, allowing for elevated line pressure mode and pressure-biased operation. This construction ensures media isolation from sensitive interior elements of the transducer, enabling the selection of materials that can come into contact with the pressure medium for specific applications. The dual, nested aneroid sensors work together to produce a linear displacement in response to an applied pressure differential. A cantilever beam assembly flexes in proportion to this displacement, providing accurate pressure readings. The fluid-filled sensing system includes nested aneroid capsule diaphragms, which support high line pressure use and enhance the overall functionality of the device.
Another significant patent is the "Explosion Inhibiting Potentiometer Assembly and Drive Mechanism Therefor." This invention features a potentiometer housed in a protective casing, operated externally through an orifice. The design includes an O-ring slip clutch that engages the potentiometer drive stem, along with a spring-urged flange that inhibits the propagation of internal explosions to the outside environment. This innovative approach enhances safety and reliability in various applications.
