Application
The instrument VS4 is a very simple and economical
solution for monitoring mechanical vibration. It contain both
sensor and signal conditioning circuit. The Vibration Detector VS4 works completely
autonomous without any cabling or external power supply. Two
LEDs indicate the alarm status. It can be mounted, for instance,
at a rotating machine and will provide information about the
running condition if it is observed in regular intervals. Both instruments
can be used with minimal installation and training time.
Typical applications are:
-
Vibration monitoring of fans, pumps, compressors etc.
-
Vibration detector for track vehicles
-
Emergency shut-off in production installations where vibration may endanger personnel and equipment
-
Monitoring vibrations as part of process control
-
Protection of fragile goods during transportation
-
Safety switch at doors, gates etc.
