 Vibrocontrol
800
The VIBROCONTROL 800 combines vibration pickup and
monitoring electronics into a small compact cast aluminum
housing to continuously monitor the effective value of
vibration velocity. Units come with a six-lead high voltage
cable for electrical connection and can be mounted directly
to the machine housing at, or near, the bearing location to
be monitored.
Other features include: |
|
• |
Built-in transducer with adjustable vibration
levels. |
|
• |
Six pre-selectable vibration ranges. |
|
• |
One pre-settable limit value with built-in
heavy-duty relay and two selectable response delay times. |
|
• |
Designed to meet ISO 2372 requirements. |

Literature Library.

 Vibrocontrol
920
The VIBROCONTROL 920 is a single channel vibration monitor
that accepts virtually any pickup including velocity sensors
and 2, 3, or 4 wire accelerometers. A user-friendly
microprocessor program gives operators the security of
password protection while allowing them to pre-program
limits for warning devices in the event components
deteriorate. Higher limits can also be set which will
automatically shut the equipment down before a catastrophic
failure occurs. A third "okay" relay continuously
monitors pickup, cable and circuit connections to ensure
proper system performance and protect against faulty
signals. The VC920 features a 4-20 mA output for system
integration with a PLC, and a buffered output for instant
vibration analysis. Present vibration measurements can
always be visually inspected using the convenient LED
indicator on the face of the instrument. The VC920 accepts
all power supplies and is easily mounted on rails or within
a cabinet enclosure.

 Vibrocontrol
1000
The Vibrocontrol 1000 can provide the most economical
solution when monitoring a single machine parameter will
protect the machine in question. While the technical aspects
of the VC1000 are very similar to that of our Vibrocontrol
920, this unit also comes in an IP 65 industrial housing and
can be directly mounted onto the machine casing, or in a
control cabinet as required.
Three different system configurations are available
depending upon the machine that is being monitored. Which
measurement parameter and which configuration is required
are mainly dependent on the type of machine and its
application requirements. The three different configurations
are as follows: |
| Absolute bearing vibrations |
 |
| For use when monitoring the rapid movements of
the bearing caps and bearing housings. Either
electro-dynamic or piezo-electric vibration sensors mounted
in the horizontal and/or vertical and/or axial directions
measure these movements of the machine bearings. |
|
| Relative Shaft Vibrations |
 |
| For use when monitoring the rapid movements of the rotor shaft relative to the bearing housings. These measurements are exclusively performed on journal bearings, for which each bearing is fitted with two radial mounted at 90° offset to each other non-contact eddy current sensors.
|
|
| Axial Shaft Position |
 |
| For use when the journal bearing machine changes in the axial distance between the axial bearing and a thrust collar are considered. This measurement is performed using non-contact eddy current sensors. |

Library.

 Vibrocontrol
1100
VIBROCONTROL 1100 provides maximum protection for units
critical to operation with a unique two-channel capability
that can monitor the vibration and bearing condition (BCU)
simultaneously. Signals from either an accelerometer or
absolute vibration velocity (seismic) transducer can be
converted into a variety of measurement parameters such as
acceleration, velocity, displacement or BCU. (Note: an
accelerometer is required to measure vibration acceleration
and Bearing Condition Units). For each channel a DC current
or DC voltage proportional to the measured value is always
available for the connection of an analog meter and/or PLC.
The microprocessor controlled monitoring unit is equipped
with six adjustable alarm limits which can be pre-programmed
and configured with audible, visual and circuit alarms in
the event components deteriorate. Systems can even be
programmed to shut the equipment down and avoid catastrophic
failure.
The VC1100 has a rugged - NEMA4 - heavy aluminum case that
can be permanently mounted in nearly any industrial area.
Units can be set up manually, via the 5 button keypad, or
automatically with the optional setup software package via a
PC. Up to 205 units can be daisy chained together and then
linked to a PC or process controller for a complete
machinery protection program. The software package allows
bar graph viewing of measured parameters, in addition to
alarm and relay status. The design of the Vibrocontrol 1100
provides affordable, state of the art, 24 hour protection
from excessive vibration for either a single machine
critical to your process, or for your entire plant.
