Description
The VMS is a state of the art vibration monitoring system. It is a compact device designed to provide simplicity and facility of usage and maintenance.
It provides data acquisition and storage, as well as communication facilities to operate on the field and send the data to a remote server.
It is bundled with internal geophones for velocity measurement with in-situ calibration possibility. The VMS provides facility to measure the characteristics of the geophones and calculate correct coefficients to provide a frequency linear response from 0.1 to 350 Hz.
