Robertshaw Vibration Monitor Model 366

*Special on 366-A8*

Robertshaw Model 366 vibration switch The Model 366 series of vibration switches are  sensitive to vibration in a direction perpendicular to its mounting base.

The product contains a vibration detecting mechanism, which also functions as a "mechanical amplifier" to activate a snap-action switch when the set level of vibration is exceeded. The vibration switch is meant to react to the total destructive force(s) acting on the equipment and is available with a manual and remote reset option.

The Model 366 vibration switch is an acceleration sensitive instrument that measures the total acceleratory shock present on the machine. When the vibration level of a vibration switch protected machine exceeds normal by a pre-selected amount, an internal switch closes, actuating either an audible warning system or a shutdown circuit before costly damage occurs. Failing bearings, broken blades and similar malfunctions cause increased imbalance or high frequency vibration detectable with the vibration switch. This product is designed for maintenance-free service in permanent installations where general purpose weather-resistant enclosures are required.
