The Model 365A-A8 vibration switch provides protection for large motors, pumps, compressors, and other rotating equipment by alerting the user to excess vibration. Failing bearings, bent shafts, broken blades, over-speeding and similar malfunctions cause increased imbalance or high frequency vibration detectable with the model 365A vibration switch. The instrument may be wired to actuate an alarm or cause a shutdown before costly damage occurs. The switch is designed for maintenance-free service in permanent installations.

Acceleratory measurements made by the vibration switch are the summation of all the individual accelerations giving a total destructive force acting on the machine - the result is positive worry free protection.
