2HZ Triaxial Geophone 3D Geophone for HVSR and Nakamura Method
The 2Hz three-component geophone represents a pinnacle of electromechanical innovation, serving as a sophisticated sensor within its compact design. This remarkable device incorporates three precisely calibrated 2.0 Hz geophones, ingeniously aligned in an orthogonal configuration within a hermetically sealed enclosure. With its vertical orientation defining the Z-axis, eastward positioning representing the X-axis, and northward alignment denoting the Y-axis, this geophone is meticulously crafted to capture seismic signals with unparalleled precision from three distinct dimensions. These signals are effortlessly transformed into electrical pulses, thanks to the sensor's exceptional attributes including high sensitivity, remarkable accuracy, and a perfect dampening factor. Its robust construction ensures excellent consistency, while its water-proof capabilities guarantee reliability even in challenging environments. Additionally, the geophone is equipped with a leveling bubble for optimal installation and features clear directional guidance. When paired with a deep seismograph, this device excels in detecting seismic activities across a multitude of applications, from earthquake prediction to structural analysis and beyond.
The 3D Land Geophone is engineered for superior performance in HVSR, MASW, and Vibration Analysis. It boasts one vertical and two horizontal sensors, each with a 2Hz resonance frequency, housed in a rugged, waterproof casing. This design ensures they are optimally coupled for precise measurement. The device comes complete with adjustable feet for stability and interchangeable rods for versatility, making it an indispensable tool for comprehensive geophysical analysis.
This advanced Triaxial Geophone is expertly crafted to harness ground pulsations, seamlessly transitioning its application to both S-wave and ambient noise analysis. Its adeptness in practical scenarios is further emphasized by its wide-ranging applications. Predominantly, the HVSR technique is harnessed for critical tasks including site classification, site effect studies, and mineral exploration. Furthermore, it plays a pivotal role in acquiring comprehensive data on underground average shear-wave velocity structures, establishing itself as an essential instrument in geophysical research and exploration.
