User Manual
•
Move the vibration transducer to each end of
the machines in a train.
• Position the vibration transducer axially at these
locations for these measurements.
• Keep track of the phase for each measurement
location.
¾
As the vibration transducer is moved
to each location, its direction keeps
changing from North to South, for
example. When it changes direction,
phase will shift from 12 o’clock to 6
o’clock.
If you move across a coupling and phase does not
change as expected, a misalignment condition can be
the cause.
Motion Studies
The Strobe Light can be a useful tool to determine
how a mechanical support or a piping system is
moving. It allows the user to find points of maximum
motion as well as minimum motion. This is important
if a new pipe hanger is to be installed or if a brace is
going to be added to dampen a vibration condition.
For these tests the strobe light should be set on a
tripod. You will need a long cable for the sensor. The
sensor should be mounted on a magnetic base.
Follow the same 5 steps outlined in the previous
section for preparation for phase analysis, and then
follow these steps:
• Mark the piping system in given intervals and
note the location of supports or hangers. For
