Adhesive mounting
Applies to sensors of series VIB 6.12x, VIB 6.14x,
and appropriate mounting adapters VIB 3.431 /
VIB 3.430.
Required tools and resources
– Hand-held drill and drill bit (3.5 mm)
– Angle grinder and rasp
– Torque wrench with 19 mm / 3/4“ hex socket
– Compressed air for cleaning out the hole.
– Solvent for degreasing
– Threadlocker (LOCTITE 243)
– 2-Component adhesive (WEICON HB 300,..)
Note
Switch off the machine and secure it against a
restart. Do not switch on the machine until the
adhesive has hardened (approx. 24 hours).
Select the point of installation
• The point of installation must have direct con-
nection to the bearing carrier if the sensor
should measure shock pulse signals.
• Allow sufficient space for applying the adhesive
with a wooden spatula.
Prepare bonding location
• Grind down existing coats to the bare metal (Ø
> 30 mm,
G
).
• If necessary, grind down the location (
G
).
• Sand down the point of installation with a rasp
and file several grooves in a diamond pattern
for greater adhesive strength (
G
).
Optionally, and only if drilling is possible:
• Drill hole for centering pin: 3.5 mm / 5 mm deep
(
H
). Remove the centering pin from the mount-
ing adapter if drilling is not possible.
• Blow out the hole.
• Clean the contact surfaces of the mounting
adapter and the machine with solvent.
• Allow contact surfaces to dry.
Apply adhesive
• Prepare the adhesive for use.
• Apply the adhesive with a wooden spatula
evenly to the base of the mounting adapter and
the bonding location (approx. 1 mm thick,
I
).
Affix mounting adapter
• Press the adapter gently against the bonding lo-
cation and turn it to evenly distribute the adhe-
sive. If applicable, screw in the centering pin (
J
).
• Do not remove excess adhesive. If necessary,
apply additional adhesive around the bonding
location for greater stability.
• If necessary, use adhesive tape to hold the
adapter in place during hardening.
Mount sensor
• Clean the contact surfaces of the sensor and the
adapter with solvent.
• Allow contact surfaces to dry.
• Thinly apply LOCTITE 243 to improve signal
transmission.
• Screw in the sensor and tighten with a torque
wrench (3 Nm,
F
).
• Check the sensor for tight mechanical fit.

Magnetic coupling
Applies to sensors of series VIB 6.14x (M5) and ap-
propriate magnetic holders (VIB 3.420, VIB 3.422).
Mount sensor
• Screw the sensor into the holder by hand.
• Place the holder with its outer edge on the mea-
suring location and lay it down in a controlled
movement.
• Check the sensor for tight mechanically fit.
Notes
At close-up range, the magnetic attraction can
be unexpectedly strong. An uncontrolled, heavy
snap-on mounting can exert high shock loads on
the sensor and impair its function.
Shock pulse (roller bearing condition) and cavita-
tion measurements are not possible with a mag-
netic coupling.
When disconnecting, grasp the sensor and the
magnet adapter. Do not pull on the sensor cable!
