Robertshaw Model 365 vibration switch for hazardous areas This unit is no longer available - see the 365A



The Model 365 vibration switch is an acceleration sensitive instrument resistant to hazardous environments that measures the total acceleratory shock present on the machine and will be triggered when the total acceleration exceeds its designated threshold.

Description

Around the globe, companies have come to trust Robertshaw's line of innovative industrial products.  Their well known valves, controls, and sensors provide unsurpassed reliability.

The Model 365 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 365 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.
