QA-30 Triaxial accelerometer<\/strong><\/p>\n

Paroscientific's seismic sensor product line offers the unique advantages of the resonant quartz crystal technology for seismic and geodetic measurements. Traditional broadband seismometers do not have the range to measure strong seismic events and traditional strong motion sensors lack the sensitivity or stability to make good long-term measurements. High resolution measurements of earthquake shaking, tilts, Earth tides, slow slip events and geodesy are required over a time spectrum spanning fractions of a second to years The remarkable performance of these sensors is achieved through the use of a precision quartz crystal resonator whose frequency of oscillation varies with acceleration induced stress.<\/p>\n

The QA-30 and QA-15 triaxial accelerometers have a full-scale range of 3 g and 1.5 g respectively.
\nThe QA-30 is highly compact and has a high resonant\nfrequency (>150 Hz). The QA-15 offers an order of\nmagnitude lower noise than the QA-30 and has a resonant frequency close to 25 Hz.
\nBoth sensors have an internal alignment matrix that uses the invariance of the Earth\u2019s gravity vector as a reference to measure seismic events and resultant earth movements. Improved, high-resolution measurements of earthquakes, tilts, slow-slip and long-term events can be made.
\n\u00c8 possibile effettuare misurazioni ad alta risoluzione di terremoti, inclinazioni, eventi \u00a0di slittamento lenti ed eventi a lungo termine.
\nAll units come with a limited five-year warranty with first two years covered at 100%.<\/p>\n
