Title: Innovations by James E. Walish
Introduction
James E. Walish is an accomplished inventor based in Buffalo, MN (US). He has made significant contributions to the field of pressure transmitters, holding a total of 2 patents. His work focuses on enhancing safety and functionality in industrial applications.
Latest Patents
One of his latest patents is for a decorative cap for a process transmitter. This innovative pressure transmitter features a flame isolating plug. The design ensures that the transmitter provides an output indicating the pressure difference between line pressure and the atmosphere outside the transmitter. It achieves intrinsic safety by coupling the sensor cavity, as well as other cavities where ignition can occur, to the atmosphere only through flame quenching paths. The opening in the transmitter housing, where the sensor is mounted, includes a plug that holds the sensor and a fitting couplable to the pressure line. An isolator transmits the process pressure to the sensor through an isolator diaphragm, acting on an incompressible filling in the sensor cavity. This design transmits pressure through a hole shaped to provide a flame quenching path, effectively isolating the sensor from the process fluid line. The opposite side of the sensor connects to the atmosphere only through flame quenching paths due to the passageway shape. The plug assembly is designed for easy insertion and removal, providing intrinsic safety even in the event of component failures, such as the isolating diaphragm or welds.
