The vibration monitor is used for the measurement and control of ground vibration and air overpressure due to blasting, piling or other ground vibration generating devices.

Vibra

Logs Peak Particle Velocity (PPV) and Peak Particle Acceleration (PPA) in 3 dimensions continuously or subject to selectable
    (time or level based) trigger
Additional measurement parameters for each channel including dominant frequency (of the maximum PPV for each measurement period)
    and peak acceleration
Captures time traces of the velocity waveform
Geophone’s design ensures flexibility and accuracy, when positioning onsite
Rugged construction makes Vibra ideal for monitoring on construction sites
The measurement period is programmable from 1 second to 999 seconds and the system will store up to 37800 sets of full results
    (this equates to more than 3 weeks for measurement periods of 1 minute or more)
External alarm beacon available
Full PC analysis software provided as standard with each Vibra

Vibra+
Offers all the features of the Vibra, in addition providing:-

GSM remote connection enabling results to be obtained remotely via email
FFT narrowband analysis used to determine the dominant frequency of the maximum PPV.
Peak displacement recorded for each channel
