Fluke PRUFTECHNIK VIB 6.172 Programming manual

Accelerometer (100mV/g)
VIB 6.172, VIB 6.210
Installation and Operation

2
Accelerometers of the VIB 6.172 and VIB 6.210
series are used for the measurement of absolute
casing vibrations on machinery with rotating com-
ponents. Due to the very low limit frequency, the
accelerometers are particularly suitable for very
slowly rotating components (n >6 rpm) such as
the main bearings of a wind turbine.
The accelerometers have a voltage output accord-
ing to IEPE standard*.
*IEPE = Integrated Electronics Piezo Electric.
More common than „IEPE“ is the manufacturer designation
„ICP®“, which is property of PCB Piezotronics Inc.
Safety Information
•Read these operating instructions carefully and
store them.
•Observe the operating instructions of the con-
nected devices.
•Read and observe the safety information in
these operating instructions!
•Only use the accelerometer as intended and for
the permitted purpose of application.
• Use original accessories only.
• Replace defective accelerometers and cables.
• Installation by qualified personnel only.
•Comply with the applicable safety regulations
when performing installation work on running
machines.
•Comply with the applicable safety regulations
when laying cables.
•Observe the technical data and the allowed
operating conditions. In case of doubt, consult
with PRUFTECHNIK.
•The accelerometer is in compliance with Eu-
ropean Directive 2004/108/EC. The complete
Declaration of Conformity is available at www.
pruftechnik.com.
Repair and Maintenance
The operation of the accelerometer is mainte-
nance-free. A repair is not possible.
Disposal
Dispose of the accelerometer after use in accor-
dance with applicable national regulations.
Mounting
The frequency response and dynamic range of an
accelerometer can be greatly influenced by the
installation. Poor coupling to the measurement
location can adversely affect the signal and restrict
the frequency range. In principle, the accelerome-
ter needs a non-positive, resonance-free and rigid
fastening to the measurement location, especially
for measurements with high frequencies.
The most secure and stable coupling is provided
by a screwed mounting, for which a M8 threaded
pin is attached to the accelerometer base by de-
fault. For both accelerometer series, depending
on the requirements on site, various mounting
adapters are available as an accessory.

– Screw adapter M5-flat, VIB 3.439 (h*= 1)

•Clean the area around the mounting hole and
roughen it with abrasive paper (type 220).
•Clean the contact surfaces of the accelerometer
/ adapter and of the machine with solvent.
•Allow the contact surfaces to dry and then ap-
ply a thin film of screw paste (LOCTITE 243) to
improve signal transmission.
•Screw in the adapter and tighten with a wrench
Adapter: 10 to 20 Nm
•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.
Mounting the bonded adapter
Tools required:
– Hand-held drill
– Drill bits with depth gauge (3.5 mm)
– File
– Compressed air for cleaning out the hole
– Two-component adhesive (WEICON HB 300,..)
Note
The machine must be switched off during instal-
lation. Afterwards, it must not be switched on for
at least 24 hours to prevent mechanical vibrations
during the hardening process.
• Select bonding position:
Leave enough space around the adapter in order
to apply the bonding compound.
• Flattening and roughening:
Sand down any paint on the mounting surface to
bare metal (Ø > 30 mm).
Level out the mounting surface if necessary.
Roughen the mounting surface with a file (filing a
few grooves in a diamond pattern provides great-
er adhesion.)
Optional, and only if drilling at the mounting lo-
cation is possible:
• Bore hole for centering pin.
– Drill depth approx. 5 mm, Diameter 3.6 mm.
If drilling is not possible, the centering pin on the
accelerometer base can be removed.

• Clean location and mix bonding compound:
Clean mounting surface and bonding socket with
a residue-free degreasant and a clean cloth. Then
allow both metal surfaces to dry completely.
• Mix bonding compound for use.
• Apply bonding compound:
Apply a thin layer of bonding compound evenly
with a wooden spatula (approx. 1 mm thick) to
the base of the adapter and the mounting surface.
• Mount adapter:
Press the adapter gently against the mounting
surface and turn it a little to evenly distribute the
bonding compound. Do not remove excess bond-
ing compound. Additional bonding compound
can be applied at the bonding location for higher
stability.
Note
An adhesive tape may be used to hold the adapter
in place during the first hour of hardening.
