VMS (Vibration Monitoring System) is the next generation instrumentation for vibration monitoring due to its computing algorithms and electronics architecture.
VMS is an “all-in-one-design” device. It contains one 24-bit digitizer, MEMS sensors, Geophones, SHM (Structure Health Monitoring) and EEWS (Earthquake Early Warning System,) algorithms.
In addition, VMS has 6-channel outputs (3 axis in acceleration and 3 axis in velocity) with precision time synchronization.
Users may analyze a set of vibration data with acceleration and velocity at the same time.
Moreover, with SHM and EEWS algorithms built-in, VMS is capable of calculating parameters on-site.
This enhances faster data processing. By built-in many breakthrough features, VMS offers a total solution for vibration monitoring.
