Horizontal Pumps Metrix Vibration

Horizontal Pumps. Because of the oil layer, a vibration signal produced by the shaft does not have a path to travel to the machine casing. That means that a seismic sensor placed on the case of the pump cannot properly sense what is going on with the shaft. This makes it necessary to use proximity sensors to
