Preparing Sensor
Mounting Locations
Stud Mount
1. Prepare the spot face and end milling tool by setting the drill bit depth
to a minimum of 0.325 inches (325 mils).
2. Using the wire brush and plant-approved cleaner, clean and degrease
the surface area.
3. Keeping the spot face and end milling tool perpendicular to the
machine surface, drill into mounting location until face has a minimum
finish of 63 micro inches (.063 mils). This will require the spot facing
tool to remove approximately 0.04 inches (40 mils) from the face. The
surface should be smooth to the touch with no noticeable
irregularities. The process is illustrated in Figure 3-2.
NOTE
If the spot face is not uniform on all sides, this is an indication that the spot
face tool was not perpendicular to the mounting surface (Figure 3-3) and the
resulting surface will not allow the sensor to be mounted properly.

process for sensor mounting.
This spot facing should result in
a uniform “seat” being created.
