Trending
Trending, or repeated vibration measurements kept in a
spreadsheet over time, is the best method to track
machine health. The product CD supplies a custom
Class III: Large prime-movers and other large
machines with rotating masses mounted on rigid and
heavy foundations that are relatively stiff in the
direction of the vibration measurements.
Microsoft Excel template that helps you to evaluate the
measurements. See Export Data on page 35 for more
information about the template and measurement plots.
Class IV: Large prime-movers and other large
machines with rotating masses mounted on
foundations that are relatively soft in the direction of
The Excel template also can give an Overall Vibration
Severity that refers to one of three ISO Standards:
? 10816-1
? 10816-3
? 10816-7
A brief description of each standard and terms is as
follows:
vibration measurements (for example, turbo generator
sets and gas turbines with outputs greater than
10 MW).
ISO 10816-3
This standard is used to evaluate machine vibration by
measurements on non-rotating parts, for industrial
machines with nominal power above 15 kW and nominal
speeds between 120 RPM and 15,000 RPM when
ISO 10816-1
measured in situ.
This standard contains general guidelines for machine
vibration measurements on non-rotating parts.
Key terms
Rigid: A machine foundation with the machine
Key terms
Class I: Individual parts of engines and machines
integrally connected to the machine in normal
operation. Production electrical motors at a maximum
of 15 kW are examples of machines in this category.
Class II: Medium-sized machines (typically electrical
motors with 15 kW to 75 kW output) without special
foundations, rigidly mounted engines or machines (up
to 300 kW) on special foundations.
supports rigidly attached to the machine skid and/or
the solid floor of the facility.
Flexible: A machine with flexible attachment between
the machine supports and foundation or facility floor.
The most common example of this is a machine in
which vibration isolators (flexible vibration damping
mechanisms) separate the machine and foundation.
Group 1: Large machines with rated power above
300 kW and not more than 50 MW (electrical
machines with shaft height: H ≥ 315 mm).
