Accelerometers are used for recording large amplitude vibrations that are common within a few tens of kilometers of large earthquakes - these could be also called strong-motion seismometers. These instruments were designed to record the high accelerations that are particularly important for designing buildings and other structures.

All GeoSIG accelerometers are available for measurement in 1, 2 or 3 axes. Downhole versions are also available.

The AC6 series of accelerometers is the newest generation of sensor from GeoSIG using MEMS (micro electro-mechanical systems) technology.

Specifications:
• Full Scale Range: ± 2g (optional ± 0.5, ± 1 or ± 3 g)
• Type: Force balance Accelerometer
• Dynamic Range: >120 dB
• Nonlinearity: <0.1%
• Bandwidth: DC to 100 Hz
• Full Scale Output: 0 ± 10V DC, 0 ± 5V DC, 2.5 ± 2.5V DC, 0-20mA
• Supply: 9.2 - 15 VDC, 70mA @ 12V
• Enclosure: IP65, Cast aluminium

While the AC6-series is the latest technology, there are a range of other sensors available from GeoSIG for acceleration and velocity. Please call for more details.
