Güralp has been developing revolutionary force-feedback broadband seismic instrumentation for more than thirty years. Our sensors are used worldwide by academic, public, governmental and private organisations to understand, protect and explore our world.
Our sensors employ the principle of negative force feedback to minimize the motion of the mass, and keep it centred within the seismometer casing. This technology vastly extends the bandwidth and linearity of the seismometer, recording seismic signals with long periods of over 300 seconds to over 100 Hz.
Güralp sensors record seismic events and signals of all kinds, from teleseismic events occurring on the other side of the planet, to microseismic events induced by human activity. Our high fidelity digitisers ensure that these signals are recorded with the highest resolution and accurate timing.
Our range of products and services meet the most complex of requirements for deployment in the most challenging circumstances. We are continuously developing new ways of engineering our proven precision technology into smaller and more advanced casings. You will find Güralp instruments gathering seismic data in the harshest of environments, from the Antarctic ice sheet; to boreholes 100s of metres deep; to the world’s most active volcanoes and deepest ocean trenches.
