The 365A-D8 vibration switch provides two spdt switches to actuate an alarm and, 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 individualaccelerations giving a total destructive force acting on the machine.
