MG4-1 MEASURING UNIT

CE Approved

 

 

 

 

Select exactly what you need:  Safeguard your plant stoppers and other essential machines.  The MG-4 is a stand-alone continuous
monitoring unit, ideal for automatic surveillance of unmanned machines.
MG-04 uses:

•     True RMS vibration severity measurement on one or two channels.

•     True SPM bearing condition evaluation on two additional channels.

More than 90% of all mechanical faults are announced by increasing vibration or shock pulse levels.  Planned maintenance and
condition triggered emergency shutdown prevent accidents and production stops.

A cost-efficient package of options:  Breakdown costs are always too high.  MG-4 is insurance with a payback guarantee.
Choose the channel combination that gives maximum safety at lowest cost.  Measuring ranges, two-step alarm levels, alarm delays,
and relay combinations can be programmed.  Condition evaluation is automatic.  There are no operating costs: install and feel safe.

Dependable condition monitoring:  Good asset management requires preventative maintenance based on condition information.
MG-4 uses the two most reliable methods for automatic machine fault detection.  It provides:  (1) shock pulse for early warning in case
of poor bearing lubrication, stressed bearings, or the onset of damage, (2) maintenance alert in case of a significant increase in
vibration severity.

Early condition alert is the best money saver - ample planning time for maintenance, no production stop, no damage.  The analog
outputs can send on-line condition information to your PLC.  As an alternative the MG-4 can be equipped with a RS-485 port
for sending complete date on LAN (Modbus network using RTU).

For better economy:  Breakdowns happen, but the big bang can be avoided.  A shut down circuit, triggered by a sudden
heavy increase of the vibration level, prevents (1) danger to personnel and other hazards, (2) secondary damage to machine and
surroundings, (3) unnecessary production stops and quality losses.

Good condition monitoring equipment has a very short payback time.  Consider the downtime cost for your last machine failure,
then make a sound investment.

Sound technique, fit for anything:  MG-4 is easy to install on all types of rotating machinery.  A wide range of transducers
and installation accessories has proved reliable in many harsh industrial environments.
