• Clean the contact surfaces of the accelerometer
/ adapter and of the machine with solvent.
• Allow the contact surfaces to dry.
• Apply a thin film of threadlocker (LOCTITE 243)
to improve signal transmission.
• Screw in the accelerometer / adapter and tight-
en with a wrench.
Maximum torque:
– 11 Nm, accelerometer VIB 6.195 w/ M8 thread
– 11 Nm, adapter VIB 3.437
– 3 Nm, adapter VIB 3.439
• Screw in the accelerometer by hand (3 to 7 Nm).
Notes
Excessive torque can damage the threads on the
accelerometer or machine part. Too little torque
can allow the accelerometer to work loose and
cause measurement errors!
If the accelerometer is affixed to non-grounded
machine components (e.g. belt-driven fan), the
accelerometer must be grounded to prevent static
charges.
Adhesive mounting
Applies to bonded adapter VIB 3.433.
Required tools and resources
– Hand-held drill and drill bit (3.5 mm)
– Angle grinder and rasp
– Compressed air for cleaning out the hole.
– Torque wrench with 22 mm / 7/8“ hex socket
– 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
• 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,
A
).
• If necessary, grind down the location (
A
).
• Sand down the point of installation with a rasp
and file several grooves in a diamond pattern
for greater adhesive strength (
A
).
Optionally, and only if drilling is possible:
• Drill hole for centering pin: 3.6 mm / 5 mm deep
(
B
). 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.
