    Abstract: A method for monitoring a rotating equipment through a condition monitoring device is performed in every predetermined time period after every predetermined time interval. The method comprises detecting presence of vibration in rotating equipment based on a signal associated with vibration in the rotating equipment. The signal is measured with one or more sensors of the plurality of sensors. Upon detecting presence of vibration, a predefined number of samples associated with the vibration is acquired at a first frequency. A Root Mean Square (RMS) value of vibration is calculated using predefined number of samples. The calculated RMS value of vibration is compared with a reference value for detecting an operating status, which is stored for every predetermined time interval. Thereafter, the method comprises processing the stored information to assess a condition of the rotating equipment.

    Abstract: A method for monitoring a first machine and a second machine is described. The machines are rotating machines. Sensor devices are coupled to the machines. The method includes synchronizing a first sensor device and a second sensor device; sensing, by the first sensor device, an operating parameter of the first machine; and sensing, by the second sensor device, an operating parameter of the second machine. The sensing of the second operating parameter is synchronized to the sensing of the first operating parameter. The method further includes broadcasting, by the first sensor device, a data packet comprising the sensed operating parameter of the first machine; receiving, by the second sensor device, the data packet sent by the first sensor device; and calculating, by the second sensor device, a performance indicator from the received operating parameter of the first machine and the sensed operating parameter of the second machine.
