There are several ways to view the impact of maintenance practices using ESA and electrical measurements, the first is the use of simple overall kilowatt readings from a power analyzer or relay monitoring system; the second is the before and after readings from an ESA device that identifies kilowatt data by defect.
Velocity is used as a vibration measurement for most condition monitoring applications because velocity is the best overall indication of machinery health for both low-speed and intermediate-speed components.
Today we sit down with Peter Eitnier, the Senior Applications Engineer for Wilcoxon Sensing Technologies. He will be going into detail on best practices and troubleshooting for permanently installing accelerometers. Vibration sensors and acelerometers should be mounted, in general, as close as possible to the bearings. The shaft turning speed is the driving force for both the machine itself, and the vibration signal.
It’s on all of the vibration fault charts, it’s taught in vibration classes, and it’s used for balancing – but how often is phase actually used by vibration analysts to confirm faults?
Imagine trying to measure the a 100° F temperature with a thermometer with a high value of 80° F, or your local police trying to catch speeding cars with a radar gun that only goes to 20 MPH. Both situations share the same problem, the sensor is not appropriate for their use!
Fans are a very common component in industry, they are used to move air from one place to another. Fans are used in dust collection, supplying air to boilers, providing ventilation to factories, are used in the manufacturing process and more.
