Installation
The frequency behavior and dynamic range of the
sensor can be heavily influenced by installation.
Poor coupling with the measurement location
dampens the signal and restricts the frequency
range. As a general rule, the sensor requires
firm, friction-locked, contact and resonance-free
attachment to the measurement location. This
particularly applies to measurements at high fre-
quencies.
Basically, the following applies:
10 x Weight Sensor < Weight object to be measured
The stabilized coupling can be achieved by screw-
ing the sensor onto the measurement location. If
screw mounting is not possible or inadmissible,
the sensor can be attached with an adhesive
adapter. A magnetic coupling saves time and ex-
penditure on installation. It does however restrict
the upper frequency range.
Screw mounting
Applies to sensors of series VIB 6.12x (M8 / 90°).
Required tools and resources
– Hand-held drill
– Drill bits (3.5mm /6.8 mm) with depth gage ring
– 90° countersink bit (VIB 8.694)
– M8 thread tap
– 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 M8 / 90 °
• 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: M8 / 12 mm deep (E).
• Blow out the hole.
Mount sensor
• Clean the contact surfaces of the sensor and the
machine 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 (11 Nm, F).
• Check the sensor for tight mechanical fit.
Notes
Excessive torque can damage the thread or the
machine housing. Too little torque can allow the
sensor to work loose. Incorrect torque always
causes measurement errors!
The sensor must be protected against static
charging if it is installed on a non-grounded ma-
chine (e.g. belt-driven fan).

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!

6
Electrical connection
The signal is transmitted via a coaxial cable. On
the sensor side, the cable is assembled with a
TNC plug and, if necessary, equipped with pro-
tective caps. The other end of the cable is either
equipped with a measuring device plug or open
for the terminal connection in a stationary signal
evaluation device.
Connect the sensor
•Screw the TNC connector on the sensor and
tighten by hand.
•If the sensor is permanently installed, push the
protective cap (VIB 6.700 / VIB 6.710) over the
plug and hermetically seal the connection with
clamp rings (VIB 6.720 / VIB 6.721).

Lay the cable
•Have the electrical connection established by a
qualified electrician exclusively.
•Observe the regulations for setting up electrical
systems.
•Do not kink, pinch, knot, twist or mechanically
overload the cables.
•It is preferable to lay the cable in a cable duct or
protective tube.
•Use cable ties and Velcro fasteners to fix the ca-
bles in place.
•Do not lay cables parallel to power lines. Adhere
to the minimum spacing (> 1 m).
•Lay a loop with sufficient reserve traction ahead
of a cable gland.
•Label the cable ends to avoid getting them
mixed up
Extend the cable
•Observe the maximum cable lengths (see the
device installation manual).
•Use appropriate coaxial cables for extension
purposes.
•Connect the cable ends inside a protective ter-
minal housing.
•Mount the metallic protective terminal housing
so that it is electrically insulated. With regard to
installation outside the Ex-zone, lay the shield
wire of the incoming and outgoing line on the
protective terminal housing.
EMC protection
•Use triaxial cables in environments subject to a
strong electromagnetic load.
•Keep the coaxial cable a short distance from the
sensor.
•Connect the triaxial cable and the coaxial cable
in a protective terminal housing.
•Mount the protective terminal housing in the
vicinity of the sensor.

Ex-zone
If the cable ends are connected inside the Ex-
zone, the ignition protection type must not be
impaired with due consideration being given to
the intended use.
Prerequisites for safe operation of the signal anal-
ysis units and the sensors:
Responsibility
Each intrinsically safe company has an authorized
EX protection representative who is solely aware
which conditions, norms, etc. must be observed
in his company. Only the specialist personnel he
authorizes are allowed to work on the system.
The following installation recommendations must
be authorized by the EX protection representative:
Limiting device VIB 3.550
– The limiting device is to be installed in a switch
cabinet or housing (at least IP 20).
– The intrinsic connections for the limiting device
must be installed at a distance of at least 50 mm
from non-intrinsically safe circuits.
– Potential equalization (PA) is to be applied first
and must not be looped through.
– The signal analysis unit must be grounded with
potential equalization at the location of the lim-
iting device.
– The limiting device is the only grounded point of
the intrinsically safe circuit in the Ex-zone.
– Potential equalization is to be established be-
tween the limiting device and monitored ma-
chines.
Sensor
– Sensors of the series VIB 6.1xy DEX are electri-
cally insulated. Sensors and protective terminal
housings must be reliably protected against
physical contact. To do this, they must be fit-
ted with the IP68 option or with protective caps
beyond the insulated position and fixed with
clamp rings
Wiring to potential equalization
– A line resistance of <120 mOhm is recommend-
ed for interference protection reasons (=1.5
mm²/10 m).
– Due consideration is to be given to personnel,
goods, lightning, explosion protection - as well
as other protection types where appropriate -
for the respective customer, trade association,
insurer, state, federal government etc.
– In this regard, the relevant implementation pro-
visions are to be observed. This also applies to
provisions relating to the safety of the connec-
tion type. In accordance with these provisions,
wiring is only to be carried out by an approved
specialist who is insured for such purposes.
Connector cable
The following applies to coaxial cable:
– The shield is laid on the shield terminal of the
limiting device. PA and the shield terminal are
connected with each other.
– With regard to extension by means of a metallic
protective terminal housing, the shield must not
have any electrical contact with the housing.
The shield is to be electrically insulated.
– The metallic protective terminal housing is to be
protected against being touched by means of
heat-shrink tubing or grounding with PA.
The following applies to triaxial extension cable:
– The outer shield is laid on PA of the limiting de-
vice.
– With regard to extension by means of a metallic
protective terminal housing, the outer shield is
not laid on the protective terminal housing but
is reliably insulated. Alternatively, the metallic
housing can be insulated by means of heat-
shrink tubing.
– With regard to outward-facing cable interfaces,
the outer shield is insulated by means of heat-
shrink tubing or with an insulating cap.
Insulate shield!
