Robertshaw Vibration Monitor Model 366

*Special on 366-A8* *Special on 366A8*

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.

The 366 series has a snap-action switch that is only resettable by pressing the manual reset button or by using the reset coil. It is normal, once the switch has been adjusted for normal operation, for the switch to trip during startup and short term vibrations. The reset coil can be used to reset the switch without going to the actual unit. We usually recommend the inclusion of the reset option, since without it an operator will have to hold the Manual Reset button in during startup and go out to the equipment to reset the switch for a minor disturbance.
