Transducer Placement Procedure
Placement of the transducer block is critical when taking vibration readings. This
block must always make firm contact with the surface to ensure an accurate
vibration reading. There are very few incidents where the transducer block can be
simply placed on the surface for an accurate vibration measurement. Even when
you cannot see movement, it is possible that the transducer can actually vibrate or
"walk" on the surface during vibration activity. This creates an inaccurate reading
because the instrument will measure the block vibrating against the surface instead
of the actual vibration source. The process of leveling the transducer on a surface is
a minor part of setting up the instrument correctly. It is very important to make
sure that the transducer is secured to the surface.
The following pages list the four generally accepted procedures you can use to
mount the transducer in preparation to record vibration activity. They are arranged
in order from most effective to least effective.
