How does DHMSCare judge vibration after stops and load changes?
DHMSCare checks whether a machine is running before it judges the vibration: readings taken while it is stopped are set aside, and a machine that runs at several speeds is compared with its own normal level at each speed. When vibration settles at a new steady level, for example after a load change, DHMSCare checks whether the operation changed, and an operating state your team confirms gets its own normal level.
Stops and load changes
DHMSCare checks whether a machine is running before it judges the vibration: readings taken while it is stopped are set aside, and a machine that runs at several speeds is compared with its own normal level at each speed. When vibration settles at a new steady level, for example after a load change, DHMSCare checks whether the operation changed, and an operating state your team confirms gets its own normal level. An alert moves up to critical only when the rise keeps growing over days or a second sign confirms it, such as a matching pattern in the vibration spectrum, the breakdown of vibration by frequency.
