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.
