Procedure
1. If the equipment surface has a radius of curvature that is less than 4 in. (100 mm),
2. Using a wire brush and plant-approved cleaner, clean and degrease the surface
3. Using a two-part epoxy (such as Emerson P/N A92106)), spray the activator onto
4. Ensure that the mounting pad / base of the device is grounded to the machine case.
5. Use a multimete to check conductivity between the mounting pad and machine
3.3.3 Motor fin mount
Procedure
1. Prepare cooling fins on motor for mounting by scraping or grinding any paint or
2. Clean mounting area with a spray degreaser that will not leave a thin fil lubricating
3. Mix adhesive.
4. Apply adhesive to the sides and the bottom of the probe portion of the motor fin
5. Place the motor fin mount probe/pad between the motor fins at the location
6. Firmly press the motor fin mount probe/pad into place, ensuring the bottom of the

the mounting surface. Place a light coat of epoxy on the surface of the mounting
pad and hold firmly against the machine spot face surface for one minute.
Note
If the adhesive does not set within 1 minute, it indicates that too much epoxy is
applied or that the mounting surface is not prepared properly. Repeat steps 2–3.

desired.
• Correct motor fin mount selection is important. The probe must fit in between
the motor fins, and the bottom of the probe must contact the motor casing.
• For motors that have a space greater than ½" between each fin, motor fin
mount probe pads with a thickness of ½" are available and will reduce the
amount of adhesive needed.
motor fin mount probe/pad is touching the motor casing (this contact area is where
the vibration is transferred from the motor to the sensor).
• The tip of the motor fin mount probe/pad should be as flat against the motor
casing as possible. (Figure 2)
• The motor fin mount probe/pad should not be resting on the top of the fins – if it
does, then the bottom of the probe may not be in direct contact with the motor
casing. (Figure 3)
