 The Series VBS Vibration Switch is small, compact, and uses two easy setup dials that adjust the maximum RMS velocity set point and false trip time delay. The Series VBS is intended to continuously monitor the changes in a machine’s vibration level. The VBS takes real-time RMS vibration input and provides an analog output of velocity as well as a switching output when an alarm value is exceeded.
