First Claim
Patent Images
1. An electric valve system, comprising:
- an electric valve actuator;
a valve;
a rotating member; and
a sensor comprising at least one surface acoustic wave device, the at least one surface acoustic wave device attached to the rotating member, wherein the at least one surface acoustic wave device outputs a uniquely identifiable signal to a wireless receiver, wherein the surface acoustic wave device is configured to measure one or more of a torque and an axial thrust associated with the rotating member.
