Specifying a Vibration Switch

Specifying a Vibration Switch

Specifying a Vibration Switch

(OP)
I am considering the use of a vibration switch on a piece of equipment we manufacture to automatically shut-down when vibration becomes excessive.  The equipment has a 25 hp motor with a fan blade direct mounted to the shaft spinning at 3600 RPM.  The equipment is used year round therefore ice sometimes builds-up on the fan blades or the fan tips wear over time causing imbalance.  The vibration switch has to be weather proof (NEMA 4 or better)and fairly rugged.  Should I use a mechanical or electronic switch.  My understanding is the electronic piezoelectric type switches are more reliable than the mechanical type.  Can anyone recommed a particular manufacturer that provides good support?  I am familiar with the following manufacturers Metrix/PMC/Beta, Robertshaw, FW Murphy, Balmac, Wilcoxon, etc.  The switch does not need to provide monitoring but rather shut-down, start-up delay and remote reset.

Thanks,


Jeff

  

RE: Specifying a Vibration Switch

I agree, stay away from mechanical switches. Any of the companies you mentioned can help you out. The only one I might add is SKF condition monitoring, they have some nice switches as well.
