Our new
IMI vibration switch is priced between powered electronic switches
and mechanical switches. Further of value, the
IMI vibration switch sends the overall vibration level to
the PLC or DCS and the analytical signal outside the cell for
safe and accurate analysis. It's a win-win-win with great benefit to your customer or
prospect.
The
IMI vibration switch takes on the myths about mechanical
switches being good for protecting cooling towers.
Myth: They are "precise
instrumentation", sense acceleration, and claim in promotional
material that is best for their switch's range which is 0 to 3600
rpm. That depends on what the definition of is is.
Fact: That's not even
close! It's acknowledged among vibration analysts and the
teachers of analysts that acceleration is the poorest choice to
monitor radial vibration below 60,000 cpm. Cooling towers
run at speeds of 90 to 1800 rpm. Your tower could be
vibrating badly, visibly moving, and you would have to set your
mechanical vibration switch to hundredths of a G to sense
it and actuate. With a 5 G switch? No way! It's a mechanical device
that has tolerance, inaccuracies, temperature, aging, & setpoint issues.
Not even close.
Myth: They coin the
term "acceleratory vibration", a very unique use of the words.
What's it mean?
Fact: They do sense shock or
position. Turn a mechanical switch set at 1 G on
its side and you will hear the switch activate. Note no
vibration. One of their claims is they
"prevent further damage". We don't think that is good
enough. We don't want to see any damage. It is
preferred to get early warning of possible damage and let experts analyze
your best course of action and the timing involved.
Industry does this for other rotating machines in most modern
industrial plants. Why not cooling towers?
Your solution
The
IMI vibration switch was designed to replace mechanical vibration
switches on cooling towers. It senses radial vibration in the speeds of your motor, gearbox
and fan and offers the high degree of protection found on most
other machines throughout the world!.
You know it is the right thing to
do. We just made it
easier.
