GeoSIG offers a wide range of sensors for various purposes. Depending on the application the most suitable sensor can be identified.
- Force balanced accelerometers are available in standard or below the USGS high noise model which is a graphical and numerical representation of the vertical seismic noice levels observed worlwide.
- For structural monitoring and strong motion measurements we recommend AC-63 because of the attractive price we can offer, the ease of installation, and flexibility of this accelerometer.
- Features such as borehole versions, waterproof housing, sealed cable inlet, over voltage protection, current loop (0-20mA) and other solutions for reliable signal transmission over long cables are offered.
GeoSIG AC-63 Triaxial Force Balanced Accelerometer
Our new state-of-the-art sensor is based on a force balanced servo accelerometer concept introducing an innovative and rugged mass suspension system which yields a superior signal-to-noise ratio and temperature and drift compensation. Incorporated Digital Sensor Control provides excellent offset stability. Recommended for strong motion earthquake survey & industrial applications requiring rugged sensors, the AC-63 comes as a triaxial orthogonal package. The standard scale is ± 2 g, optionally adjustable to ± 1g or ± 0.5g. The frequency response ranges from From DC to 100 Hz to 200 Hz (Optional).
GeoSIG AC-63-DH Downhole Accelerometer
This is a specially designed down hole sensor incorporating all features of the AC-63. With the maintenance free and configurable-from-surface structure, offers a long service life under harsh conditions below the ground.
VE-53 Triaxial Velocity Sensor
The VE-53 sensor is based on a standard exploration geophone mass-spring system with electronic correction. This type of sensor give very good stability verses temperature or aging because of the very simple principle.The VE-53 sensor package is a triaxial velocity sensor designed for field or industrial survey and monitoring applications regarding vibration and explosion for civil engineering. A downhole version, VE-53DH is also available
GeoSIG AC-2x Series Accelerometers
The AC-2x Series are based on a standard exploration geophone mass-spring system with electronic correction, which yields a simple thus reliable accelerometer series. The temperature stability and light weight (2.5 kg) of AC-2x is outstanding. Recommended for strong motion earthquake survey & industrial applications requiring high sensitivity, 2x series come with two different uniaxial (AC-21H & 21V), as well as biaxial (AC-22) and triaxial (AC-23) configurations. The sensor full scale is 1g adjustable at ±0.1 g, ±0.2 g, ±0.5 g and ±1 g along with a frequency response of 0.2 Hz to 50 Hz. It is also is available as a low noise version
