`Mounting considerations
`
`Is the placement for monitoring in a safe, accessible location?
`•
`• Can the accelerometer be permanently mounted?
`– Can the machine be faced properly?
`• Mounting location
`– Where is the best location?
`– Are there obstacles?
`• What are the frequencies of interest?

`
`Mounting resonance
`
`• Mounting resonance can amplify high frequency signals and increase
`overload
`• Mounting resonance can appear to be severe rolling element and gear
`mesh faults

`
`
`
`Mounting location
`
`• Mount in the load zone
`• Mount as close to the point of interest
`as possible
`• Use low profile, side exit sensors for
`confined areas
`– Allows for neat cable routing
