 Affordable
and Reliable Condition Monitoring
If you need
information on the condition of rotating machines and you need
it now, you'll love the instant, easy to obtain results
of the Cooper CM1. Its unique principle of operation lets you
instantly check machinery, even if you have no previous measurements
and no detailed information on speed, shaft diameter or even
bearing type.
The Cooper
CM1 makes the ideal general purpose condition monitoring instrument
for busy maintenance engineers who cannot afford the luxury
of carrying out periodic measurements around a systematic route.
There are no compromises in the performance, versatility or
ruggedness of the Cooper CM1 Condition Monitor.
The 100kHz
frequency used obtains best performance readings and enables
this machine to pick up a wide range of unforeseen problems
on all rotating machines (typically, months before final failure)
and will save you and your company a fortune!
How
the Cooper CM1 Works
The Cooper
CM1 characterizes the detected signal in terms of Distress® and
dB Level. Distress® is a proprietary parameter which performs
a summation of all the microscopic clicks, crunches, whistles
and groans associated with faults. In this way Distress® provides
a means of instantly recognizing suspect machinery at a very
early stage. By contrast dB Level is a measure of the overall
signal level and is used to trend the rate of degradation of
suspect machinery.
