GeoSIG Ltd Wiesenstrasse 39 8952 Schlieren Switzerland VE-53 / VE 52 / VE 51 Short Period Seismometer Features Sensitivity Bandwidth 1000 V/m/s differential 1 to 80 Hz 0.2 to 160 Hz (BB version) Dynamic range > 120 dB (1 to 30 Hz) Excellent temperature stability High shock survivability High lifetime stability Cost effective sensor Low power consumption Simple test and calibration Strong mechanical design Downhole version (VE-5x-DH) is also available Outline The VE-5x is a triaxial short period seismometer designed The VE-5x is housed in a sealed cast aluminium housing. for field or survey and monitoring applications. The housing also incorporates a single bolt mount with three levelling screws. The VE-5x seismometer is based on a state of the art geophone mass-spring system with electronic feedback. It The broaderband version, VE-53-BB, is suitable for is ideally suited for installation in vaults with low to monitoring applications involving an extended frequency moderate noise. This type of sensor yields a very good range. Stainless steel packaging options and a downhole stability under temperature fluctuations or against aging version, VE-53-DH, are also available. effects. In addition due to the innovative design of the unit The VE-5x seismometer is directly compatible with all no mass clamping is required. GeoSIG systems.
