  • Apparatus and Methods for Direct Sensing of Rotational Dynamics of a Rotating Shaft
    Publication number: 20200277875
    Abstract: The invention and its various embodiments are directed to a telemetry system for measuring rotordynamic data from a rotating shaft of interest and methods for using the same. The invention provides a single housing that can include multiple, different sensors that measure various rotordynamic parameters, such as both strain and acceleration, in parallel. A power and data antenna is electrically attached to the housing and the sensors for receiving radio frequency power to power the sensors and to wirelessly transmit data collected by the sensors. Both the housing and the power and data antenna are attached to a rotating shaft and are encapsulated in a fiber coating.
