Stud Mounting
Stud mounting is typical for permanently mounted
applications. A hole is tapped into a flat section of the
machinery housing and the Sensor's stud is screwed into
the tapped hole.
Advantages: Highest frequency response, very
repeatable data over time. Best diagnostic quality.
Disadvantages: Less practical for "walkaround"
troubleshooting due to time needed to screw/unscrew the
Sensor from machinery, often difficult to tap a hole in the
desired measurement location.
Adhesive Mounted Pads
Typically used for permanently mounted applications. A
thin layer of adhesive is applied to the bottom of the
mounting pad and placed on a flat section of the
machinery housing. The Sensor's stud is screwed into the
hole in the mounting pad.
Advantages: High frequency response approaching that
of a stud mount without having to tap a hole, very
repeatable data over time. Next to a stud mount, best
diagnostic quality.
Disadvantages: Less practical for "walkaround"
troubleshooting due to time needed to screw/unscrew the
Sensor from mounting pad.

The advantages and disadvantages of a temporary mount
are as follows.
Magnetic Mounting
The magnetic mount uses either a 2-pole magnet (for
rounded surfaces) or flat magnet attached to the Sensor.
If you make the measurements at the exact same
location, each time, repeatable data can be collected over
time. Magnet mounts are generally more convenient and
allow faster measurement, but some accuracy is lost.
Advantages: Fastest, most convenient method for
"walkaround" troubleshooting.
Disadvantages: Diagnostic quality is less than that of
stud or adhesive mounts.
 Caution
When using a magnetically mounted Sensor,
be careful when attaching it to the test
surface. The magnet is very strong and could
pull the Sensor assembly from your hand
and impact the test surface. An excessive
impact can damage the Sensor. Hold the
Sensor firmly and carefully roll the Sensor
onto the test surface to minimize the
potential for impact.
