Installation; Screw Mounting - Fluke VIBCODE VIB 8.660 Manual

Installation

The frequency behavior and dynamic range of
the VIBCODE sensor can be heavily influenced by
installation of the VIBCODE stud. Poor coupling
with the measurement location dampens the
signal and restricts the frequency range. As a gen-
eral rule, the sensor requires firm, friction-locked,
contact and resonance-free attachment to the
measurement location. This particularly applies to
measurements at high frequencies.
Basically, the following applies:

Sensor
The most stable coupling to the measurement
location can be achieved by screw mounting. If
screw mounting is not possible, the VIBCODE stud
can be glued to the measurement location.

Screw mounting

Applies to VIBCODE threaded studs M8 / UNC
5/16.
Required tools and resources
– Hand-held drill
– Drill bits (3.5 mm /6.8 mm) with depth gage ring
– 90° countersink bit (VIB 8.694)
– Thread tap M8 or UNC 5/16-18
– Torque wrench with 19 mm / 3/4" hex socket
– Compressed air for cleaning out the hole
– Solvent for degreasing
– Threadlocker (LOCTITE 243)
Select the point of installation
• The drilled hole must have direct connection to
the bearing carrier if the sensor should measure
shock pulse signals.
• Minimum distance between the drilled hole
and protruding edges of the housing must be
35 mm (A). Allow adequate clearance to attach
the wrench.
Ensure that a hole can be drilled at the chosen
location.

Note
Drill threaded hole
• Drill pilot hole: 3.5 mm / 15 mm deep (B).
• Bore out hole: 6.8 mm / 15 mm deep (C).
• Contersink hole: 90° / 3 mm deep (D).
• Blow out the hole.
• Grease thread tap.
• Tap thread: 12 mm deep (E).
• Blow out the hole.
Mount stud
• Clean the contact surfaces of the stud and the
machine with solvent.
• Allow contact surfaces to dry.
• Thinly apply LOCTITE 243 to improve signal
transmission.
• Affix the protective cap to the stud and, if avail-
able, insert the code ring into the stud.
• Screw in the stud and tighten with a torque
wrench (11 Nm, F).
• Check the stud for tight mechanical fit.
