Condition monitoring and diagnostics of machines -
Vibration condition monitoring –
Part 1: General procedures
1 Scope
This Part provides general guidelines for the measurement and data collection
functions of machinery vibration for condition monitoring. It is intended to promote
consistency of measurement procedures and practices, which usually concentrate on
rotating machines.
Because of the diversity of approaches to condition monitoring, recommendations
specific to a particular kind of monitoring programme will be addressed in additional
Part.
This Part is a basic document which presents recommendations of a general nature,
encompassing
- measurement methods,
- measurement parameters,
- transducer selection,
- transducer location,
- transducer attachment,
- data collection,
- machine operating conditions,
- vibration monitoring systems,
- signal conditioning systems,
- interfaces with data-processing systems,
- continuous monitoring, and
- periodic monitoring.
