Function
VIBCODE is a vibration sensor system that uses
coded measurement studs for certain identifica-
tion of measurement locations on the machine.
The system consists of the VIBCODE sensor and
the VIBCODE measurement stud.
VIBCODE sensor
The VIBCODE sensor contains a code ring sensor
and a vibration sensor. The sensors locks onto the
VIBCODE stud via bayonet mount in optimum po-
sition and with consistent pressure. Trend readings
are taken with perfect repeatability regardless of
operator qualification and training. The code ring
sensor reads the tooth pattern of the plastic ring
in the measurement stud to determine its location
so that the correct types of measurement can be
taken. Mixups, erroneous trend deviations and
time-consuming repeat measurements are all
eliminated once and for all.

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:
10 x Weight Sensor < Weight object to be measured
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 (3.5mm /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.
Note
Ensure that a hole can be drilled at the chosen
location.
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.

Notes
Excessive torque can damage the thread or the
machine housing. Too little torque can allow the
stud to work loose. Incorrect torque always causes
measurement errors!
The tapered shank section must seat perfectly into
the countersunk hole so that proper signal trans-
fer from the machine to the sensor (left) can take
place over a large area of the shank.
If there is only partial contact, then transmission
will be poor (right).
Extension bar
The VIBCODE stud with extension bar is ideal for
situations such as motor housings where there is
much clearance between the actual mounting lo-
cation (e.g. the bearing housing) and the housing
cowling. This stud is available in various lengths
with an M8 or UNC 5/16 thread at its bottom.
To ensure optimal signal transmission, the hous-
ing cowling and extension bar may not come
into contact. Therefore, the feed-through for the
extension bar must have a diameter of at least
15 mm.
The longest extension (170mm and 6 5/8”) may
be used only for taking shock pulse readings and
not for vibration measurement!
Locking nut
The VIBCODE stud with locking nut is suitable for
measurement locations which are covered by a
housing cowling and can be reached without ex-
tension. The stud can also replace existing housing
screws.
To ensure optimum signal transmission, the bolt
must not touch the housing cowling. The bore
must therefore be drilled in such a way that the
bolt has a sufficient distance to the housing cowl-
ing and at the same time the housing cowling can
be tightened with the locking nut.
Bolt and housing cowling
must not touch each other

Adhesive mounting
Applies to VIBCODE studs with bonding base.
Required tools and resources
– Hand-held drill and drill bit (3.5 mm)
– Angle grinder and rasp
– Compressed air for cleaning out the hole.
– Solvent for degreasing
– 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
connection 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 stud if
drilling is not possible.
• Blow out the hole.
•Clean the contact surfaces of the stud 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 stud and the bonding
location (approx. 1 mm thick, I).
Affix VIBCODE stud
•Affix the protective cap to the stud and, if avail-
able, insert the code ring into the stud.
•Press the stud gently against the bonding loca-
tion and turn it to evenly distribute the adhe-
sive. If applicable, screw in the centering pin (J).
•Do not remove excess adhesive. If necessary,

Performing measurement
After VIBCODE is inserted in the coded measure-
ment stud, the measuring device recognizes the
measurement location and automatically calls up
the measurement tasks for this location. Measure-
ment either begins automatically or must be start-
ed by pressing a button on the measuring device.
Additional details can be found in the measuring
device documentation.
Attach the VIBCODE sensor
• Open the protective cap of the VIBCODE stud.
•If necessary, remove the protective cap from the
VIBCODE sensor.
•Place the VIBCODE sensor on the VIBCODE
stud.
•Press the VIBCODE sensor lightly and tighten
it clockwise until stop. The sensor is locked by
means of a bayonet connection.
•Check whether the sensor is fixed correctly in
the stud.
•To unplug, turn the sensor counterclockwise
until the lock is released. Do not pull the cable.
Notes
Never use the VIBCODE sensor to take a mea-
surement directly from the machine surface. This
sensor must always be locked onto the VIBCODE
stud!
Do not remove the VIBCODE sensor from the VIB-
CODE stud during measurement.
Do not unplug the VIBCODE sensor from the mea-
suring device when the code ring is being read.
Only leave the VIBCODE sensor attached to the
VIBCODE stud for as long as necessary as, other-
wise, the spring tension of the sensor will be too
heavily stressed.
Before mounting the VIBCODE sensor on the
stud, measure the temperature of the stud with
a temperature probe. VIBCODE studs may not
exceed a maximum temperature of 70°C / 158°F
during measurement. If the measurement takes
no longer than five minutes, the temperature may
reach a maximum of 80°C / 176°F.

Cleaning
•Slight soiling on the sensor can be washed off
using soap solution or isopropyl and a cotton
cloth.
•To prevent damage to the delicate components
in the head of the sensor, use a paintbrush for
cleaning them.
•If you use compressed air for cleaning, only use
a weak jet of air.
Notes
Never use solvent for cleaning!
Do not scratch off any soiling using screwdriver
blades or other hard objects !
To prevent damage to the VIBCODE sensor and
avoid soiling, please observe the following in-
structions:
•Do not apply lubricating oil or grease to the
VIBCODE stud or sensor.
•After the measurement, always replace the
protective caps.

¨
Encoding
The stud contains a plastic code
ring that obtains an unique identity
- similar to a fingerprint - through
the removal of individual teeth. The 4-digit coded
patterns are defined with the aid of the PC soft-
ware (OMNITREND / OMNITREND Center) and
are cut out with the VIBCODE ring encoding tool
(VIB8.692).
Cut out code pattern
•Insert the code ring into the appropriate slot of
the encoding tool (1).
• Insert the plunger (2).
• Set the first code number (3).
• Slowly press down the plunger (4).
•Repeat the procedure for the next code num-
bers accordingly.
