Abstract
A system includes a sensor configured to monitor rotating machinery and generate a signal based on a physical characteristic of the rotating machinery. The system also includes a monitoring system with a processor. The processor of the monitoring system is configured to receive the signal from the sensor. The processor determines an occurrence of reverse rotation of the rotating machinery by comparing the signal to a normal operating pattern to generate an initial value. The processor generates a notification signal indicating the occurrence of a reverse rotation.
Claims20
A device, comprising:
- a communication interface configured to receive a signal related to a rotational speed, a vibration, or any combination thereof of a rotating machine element;
- a memory for storing an operating pattern of the rotating machine element, wherein the operating pattern is related to the received signal;
- and
- a processor coupled to the communication interface and the memory, wherein the processor is configured to:
- determine an occurrence of reverse rotation of the rotating machine element by comparing the signal received from the communication interface to the operating pattern stored in the memory;
- and
- generate an initial value indicative of the occurrence of the reverse rotation of the rotating machine element.
A system, comprising:
- a sensor configured to monitor rotating machinery and generate a signal based on a physical characteristic of the rotating machinery;
- and
- a monitoring system comprising a processor configured to:
- receive the signal;
- determine an occurrence of reverse rotation of the rotating machinery by comparing the signal to an operating pattern of the rotating machinery to generate an initial value;
- and
