Güralp launches two new products at the 2015 AGU Fall meeting

Güralp, the leading global provider of force feedback seismic monitoring instrumentation is launching a new low power, high fidelity, integrated digitiser and communications unit called Affinity; and Fortis, a strong motion accelerometer that has been designed to deliver ‘best in class’ performance.


The Affinity’s key features include full 24-bit resolution; an exceptionally low noise floor of >138 dB at 100sps; and sampling rates of up to 4000 samples per second.

For the first time with Affinity, Güralp will allow users access to the software environment to customise data reading, writing and signal processing. By opening the source of internal data handling and processing software, users will be able to expand the versatility of the Affinity for applications such as earthquake early warning; data triggers over low bandwidth; and applications’ proprietary data transfer protocols.

Philip Hill, Engineering Director at Güralp explains:

“When we made the decision to open up aspects of the Affinity software we did so largely in response to customer demand. The Affinity is a high performance piece of kit well suited to complex network arrangements and is built on open source Linux. Extending this open concept to include our data handling and control interface software allows users to incorporate functionality traditionally only possible with external hardware and software.  The open source concept seems to be the ultimate way in which to respond to our customer's requirements.”

The Affinity also features a fast, fully interactive user interface with state of the art timing protocols and a switchable gain to enable a wide variety of different instruments, from the simplest of geophones, to infrasound sensors and, of course, seismometers.


The Fortis is a low-power (1.3 Watt), slim-line design, just 125 mm in diameter and 99 mm high with its optional feet. The Fortis incorporates state of the art switched gain levels that will allow the instrument to perform optimally in a wide range of earthquake, structural health and civil engineering applications.

The unparalleled low noise of the instrument finally allows the gap between traditional strong motion instrumentation and the weak motion seismometer to be bridged. The instrument naturally benefits from both flat frequency response as well as controlled and flat phase response over the passband. This is a pre-requisite for accurate picking and stacking algorithms to function optimally.

For further details of both of these new products, AGU registrants can visit Güralp at stand 344.

Güralp (www.guralp.com) is a leading global provider of sophisticated seismic monitoring solutions used to understand natural seismological events such as earthquakes, aftershocks and volcanos, as well as induced seismic events, or seismic signals, resulting from human activity.

Our solutions are used in research, civil and industrial applications to increase understanding, optimise processes and to protect people and the environment. Our equipment is installed in all major ocean basins and across all continents worldwide.

Our instruments range in performance from very low frequency, very low noise for global seismology to high dynamic range instruments for local, strong motion monitoring. Our sensors and can be supplied for deployment at the surface, in boreholes and on the ocean bottom. We also provide data acquisition equipment, power and communication accessories and data interpretation software.

Our services include installation and commissioning; network operation; repair and maintenance services; data processing and interpretation.

Headquartered in Reading, in the UK, we have been operating for more than 30 years and have established a global network of distributors who provide local customer support and sales services.
