Buck Sales Inc US 366-D4, Installation Data 6000 Series Vibration Switches

The Robertshaw® vibration switch is designed to protect rotating and reciprocating equipment against serious damage in the event malfunctions occur which maybe detected as an increase in vibration. Both amplitude and frequency of vibrations are so that an increase over normal in either will actuate the vibration switch. When the vibration level of a machine protected by a vibration switch exceeds normal by a preselected amount, an internal switch is actuated providing a shut-down circuit before costly damage occurs. An audible or visual warning system may also be wired into the switch to signal when a malfunction has occurred. Falling bearings, broken blades and similar malfunctions cause increased imbalance or high frequency vibrations, detectable with the vibration switch. It is designed for maintenance-free service in permanent installations.
