Patent ID: 11959825
Assignee: ABB SCHWEIZ AG
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. A condition monitoring device for monitoring a rotating equipment, the condition monitoring device comprising:
a plurality of sensors configured to:
at beginning of a predetermined time period, measure data of the rotating equipment; and
at every predetermined time interval,
one or more sensor of the plurality of sensors configured to generate a signal associated with vibration at a measurement location relative to the rotating equipment; and
acquire a predefined number of samples associated with the vibration at a first frequency;
a network interface configured to communicate with a server;
a processor, wherein the processor in the predetermined time period, after every predetermined time interval is configured to:
detect presence of vibration in the rotating equipment based on the generated signal;
calculate a Root Mean Square (MS) value of vibration using the acquired predefined number of samples;
compare the calculated RMS value with a reference value for detecting an operating status of the rotating equipment, wherein the reference value is
calculated based on the data measured by the plurality of sensors at a beginning of every predetermined time period and is based on vibration data measured at the beginning of every predetermined time period;
store the operating status of the rotating equipment for a plurality of predetermined time interval based on the comparison;
process information stored for the plurality of predetermined time intervals in the predetermined time period, to assess a condition of the rotating equipment; and
a memory communicatively coupled to the processor.
