The VE-53 is a triaxial short period seismometer designed for seismic monitoring applications.
The VE-53 seismometer is based on a state of the art geophone mass-spring system with electronic feedback. It is ideally suited for installation in vaults with low to moderate noise.
VE-53 offers a remarkable stability under temperature fluctuations or against ageing. In addition, due to the innovative design of the unit, no mass locking is required.
The VE-53 is housed in a sealed cast aluminium housing. The housing incorporates a single bolt mounting system with three levelling screws.
The broaderband version, VE-53-BB, is suitable for applications involving an extended frequency range.
Stainless steel or Ex-proof packaging options are also available.
The VE-53 seismometer is directly compatible with all GeoSIG solutions.
