METHOD FOR MONITORING A FIRST MACHINE AND A SECOND MACHINE, SENSOR SET, AND USE OF A SENSOR SET FOR MONITORING A FIRST MACHINE AND A SECOND MACHINE

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.
