• Epoxy mounting (alternative)
• Triaxial quick connection
• Motor fin mounting
• Temporary mounting
3.3.1 Stud mounting (preferred)
Prerequisites
The mounting location must provide a flat surface of at least 1.1 in (27.94mm) in diameter
and a case thickness exceeding 0.4 in. (10.2 mm). If this is not possible, use the epoxy
mount method instead.
Stud mount provides increased reliability, improved frequency response, and increased
signal sensitivity.
CAUTION
Do not exceed the specified torque when tightening a stud-mounted device. Over-
tightening the device will damage the sensing element and void the manufacturer’s
warranty.
Procedure
1. Prepare the spot face or end mill tool by setting the drill bit depth to a minimum of
0.325 in. (8.255 mm).
2. Using a wire brush and plant-approved cleaner, clean and degrease the surface
area.
3. Keeping the spot face and end mill tool perpendicular to the machine surface, drill
into the mounting location until the surface is smooth to the touch with no
noticeable irregularities. This may require the spot face tool to remove as much as
0.04 in. (1.016 mm) or more from the surface.
Note
If the spot face is not uniform on all sides, it indicates that the spot face tool is not
perpendicular to the mounting surface, and the resulting surface will not allow the
sensor to be mounted properly.
4. Using 1/4-28 in. tap set, tap a pilot hole to a minimum depth of 0.25 in. (6.35 mm).
3.3.2 Epoxy mounting (alternative)
If it is not practical to drill into the machine casing, then the epoxy mount method is
acceptable.
CAUTION
When installing in a hazardous location, all efforts must be made to ensure that the device
is grounded to the machine case.
