Abstract

A system for use in monitoring operation of a rotating device includes at least one first sensor that senses a position of a first component coupled to the rotating device, and at least one second sensor that senses a position of a second component coupled to the rotating device. A processor coupled to the first sensor and the second sensor calculates a first plurality of property values of the first component based on the first component position, and a second plurality of property values of the second component based on the second component position. The processor graphically presents a first display including at least one trace based on the first plurality of component property values, graphically presents a second display including at least one trace based on the second plurality of component property values, and synchronizes the trace in the first display with the trace in the second display.

Dependent claims

A system for use in monitoring operation of a rotating device, the system comprising:

at least one first sensor configured to sense a position of a first component, coupled to the rotating device, with respect to a predefined axis, and to generate a signal indicative of the position of the first component;
at least one second sensor configured to sense a position of a second component, coupled to the rotating device, with respect to the predefined axis, and to generate a signal indicative of the position of the second component;
and
a processor coupled to the at least one first sensor and to the at least one second sensor, the processor programmed to:
calculate a first plurality of property values of the first component based at least in part on the first component position;
calculate a second plurality of property values of the second component based at least in part on the second component position;
graphically present a first display including at least one trace based on at least a portion of the first plurality of component property values;
graphically present a second display including at least one trace based on at least a portion of the second plurality of component property values;
and
synchronize the at least one trace in the first display with the at least one trace in the second display.

A non-transitory computer-readable storage medium having computer executable instructions embodied thereon, wherein when executed by a processor, the computer-executable instructions cause the processor to:

receive a first signal indicative of a sensed position of a first component of a rotating device with respect to a predefined axis;
receive a second signal indicative of a sensed position of a second component of the rotating device with respect to the predefined axis;
calculate a first plurality of property values of the first component based at least in part on the first component position;
calculate a second plurality of property values of the second component based at least in part on the second component position;
graphically present a first display including at least one trace based on at least a portion of the first plurality of component property values;
graphically present a second display including at least one trace based on at least a portion of the second plurality of component property values;
and
synchronize the at least one trace in the first display with the at least one trace in the second display.
