Veloget 3D Seismometer
Veloget 3D Seismometer with high sensitivity sensors designed for HVSR and seismic and civil monitoring.
VELOGET 3D
Class I triaxial seismometer, compliant with DIN 4150- 3, DIN 45669-1, UNI 9916 and UNI 9614.
It is supplied in a metal container IP66, with adjustable feet and control bubble. It can optionally request IP69 for installations in presence of water.
It is supplied in a metal container IP66, with adjustable feet and control bubble. It can optionally request IP69 for installations in presence of water.
Available in triaxial, biaxial and uniaxial configuration for vertical or horizontal applications, with military connector or cable gland for fixed installations. It consists of an electronically linearized geophonic triad, with dynamics greater than 130dB.
A special system on the bottom plate allows fixing to the floor/wall with a single plug and the three adjustment screws ensure leveling. The internal electronics provides for the management of functional tests, programmable by the user.
