GeoSIG VE-53-DH Short Period Seismometer
The VE-53-DH is a downhole, triaxial short period seismometer designed for seismic monitoring applications.
Based on a state of the art geophone mass-spring system with electronic feedback, the VE-53-DH seismometer is ideally suited for installations with low to moderate noise.
The VE-53-DH is housed in an extremely robust downhole housing of austenitic stainless steel.
Offering a remarkable stability under temperature fluctuations or against aging, the VE-53-DH also requires no mass locking due to the innovative design of the unit.
The VE-53-DH is equipped with electronic offset adjustment features that make its installation very user friendly. This powerful feature allows the users to install the VE-53-DH without mechanical offset adjustment and fine levelling.
The advanced iSensor™ interface allows easy deployment using built-in hardware like compass as well as tilt, temperature and humidity sensors.
The VE-53-DH seismometer is directly compatible with all GeoSIG solutions.
