Abstract
Official abstract text for this publication.
Non-contact torque, thrust, strain, and other data sensing of a valve actuator or valve is disclosed. A sensor may include a surface acoustic wave device.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of sensing a force in a motor-operated valve actuator, the method comprising: wirelessly exciting a plurality of surface acoustic wave devices coupled to a component of a motor-operated valve actuator; receiving a first wireless signal which is uniquely identifiable by being within a first frequency range from a first surface acoustic wave device of the plurality of acoustic wave devices; receiving a second wireless signal which is uniquely iden…
