Dual Channel Module (Vibration)
The Mechanalysis Model MIL8720 Series Module provides
dual channel vibration monitoring using suitable sensors.
Common large linear scale meter is provided for ‘higher
of two’ analog indication on the front panel.
A spring loaded toggle switch is provided on the front
panel for viewing the channels (Ch 1 or Ch 2) independently.
All controls for setup and operation are accessible
from the front panel. ALARM and TRIP set point adjustments
common to both the channels are concealed under the
machine/sensor identification plate. However, higher
of two input signal is used for comparison. One reed
relay each for Alarm and Trip are provided per module.
Relay contact rating can be enhanced to 5A resistive
@ 230V AC using Relay Expander.
Solid state ALARM and TRIP push buttons / LED lamps
(amber and red) provide three basic functions: a visual
indication when a preset vibration level has been
exceeded, to reset the relays and push to read and
adjust the set points.
A portable Vibration Analyser / Balancer or an oscilloscope
may be connected to the signal outputs on BNC connectors
for diagnosing machinery problems and for in place
dynamic balancing.
The input signal is continuously monitored to ensure
that the sensor, interconnecting cables and the module
are each functionally correct and its healthiness
is indicated by the green OK LED light provided on
the front panel.
The MIL8710 series of Single Channel Vibration Monitoring
Module (Vibration) measures in ‘microns’
or ‘mm/sec’ or ‘g’ depending
on the sensor selected. These are summarised against
the part numbers given in the table below. While placing
the order, the client must specify the listed part
number or specify the required unit and full scale
range.
