Baltimore Aircoil (BAC) 312879 Vibration Switch 110V Nema 4X

The Baltimore Aircoil (BAC) 312879 Vibration Switch is used to detect the status of the operational condition of some essential HVAC systems like cooling towers and chillers. This switch is a 110V switch with a NEMA 4X enclosure, which means that it is designed to be used outdoors. It operates based on the principle of sensing the vibration signals that are caused by mechanical faults such as bearing defects, shaft misalignment or rotor unbalance. If the vibration level is high, the switch gives an alarm signal to the maintenance personnel that the equipment may be damaged.
