The AC-23 package is a triaxial accelerometer sensor designed for Strong Motion and industrial applications where a high sensitivity is required. The AC-2x series are state-of-the-art servo-accelerometers based on standard exploration geophone mass-spring system with electronic feedback. Having remarkable temperature and aging stability because of the very simple principle, the AC-2x rarely requires maintenance.

The AC-43 sensor package is a triaxial accelerometer designed for urban and industrial applications regarding strong motion earthquake survey and vibration monitoring as well as alarm and switch systems. All these applications require rugged sensors with minimum maintenance and a simple method for periodic testing.

The AC-73 sensor package is a true electro-mechanical triaxial downhole accelerometer designed for broadband earthquake monitoring and applications requiring highly sensitive and rugged sensors with minimum maintenance and a simple method for periodic testing.

The AC-73-DH sensor package is a true electro-mechanical triaxial downhole accelerometer designed for broadband earthquake monitoring and applications requiring highly sensitive and rugged sensors with minimum maintenance and a simple method for periodic testing. The rugged mass suspension moving coil system improves the signal to noise ratio. The magnetic system and capacitive position sensors offer symmetrical controls for the accurate electronic centring of the mass. At rest the accelerometer mechanism is in balance and no electrical output is generated.

Designed and handmade in Switzerland, arolla broadband seismometer is the culmination of years of experience designing high precision, low noise, and reliable seismic equipment.

The VE Velocity Sensors are engineered for consistent performance over a long lifetime. Advanced computerised testing, manufacturing techniques and quality control are used in the production process to provide both the uniform parameters and the rugged qualities required in modern velocity sensors.

The VE Velocity Sensors are engineered for consistent performance over a long lifetime. Advanced computerised testing, manufacturing techniques and quality control are used in the production process to provide both, the uniform parameters and the rugged qualities necessary in modern velocity sensors. The sensor module has been proven world-wide for many years in different applications. The symmetrical rotating dual coil construction minimises the force on the spring arms. The use of precious metals ensures optimum electrical contact and a long operating life.

The VE-5x is a triaxial short period seismometer designed for seismic monitoring applications. The VE-5x 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-5x offers a remarkable stability under temperature fluctuations or against aging. In addition, due to the innovative design of the unit, no mass locking is required. The VE-5x 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-5x seismometer is directly compatible with all GeoSIG solutions.

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.
