Vibration Switches

Balmac’s vibration switches are electronic vibration protection limit switches for commercial and industrial rotating machinery. The switch sensors and electronics are integral and it mounts directly to the machine. Models 550, 550-X, and 555 provide 4-20 mA outputs for remote monitoring. Limit Relays connect directly to PLC,s, DCS's or other control systems.
