WZG-6B/12A MASW Seismography

WZG-6A/12A is a 24-bit wave velocity tester, under Windows Operation System, based on WZG-24 engineering seismograph. It features multiple function, high precision, high speed, high reliability and fine expansibility. Industrial PC or notebook PC is required to collect data through USB interface; built-in rechargeable battery ensures the instrument to work for over 8 hours. Seismic source for testing may be hammer, electric spark or explosion, extremely fitted for sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, and refraction or reflection survey.

Applications:

It applies to engineering geological prospecting, in various fields such as hydrology, electricity, railway, bridge, city construction, traffic, etc, and in petroleum, coal, uranium and groundwater exploring.



Functions:


•   Wave speed (sheared wave) survey
•   Transient multifold Rayleigh wave prospecting
•   Multi-wave high density seismic imaging
•   Shallow refraction survey
•   Foundation pile inspection
•   Civil engineering quality detection
•   Site constant shake survey
•   Shake-to-blasting survey

Main Features:   

•   24-bit A/D---- Maximum sampling rate is 10μs and 50μs for 3-channel and 6-channel operation respectively.
•   Perfect display of original signals---- Fine amplitude consistency and phase consistency, super-low distortion, advanced high-cut filter with suppression more than 72dB (cut point changes according to sampling
frequency, without false frequency).
•   High-speed data transferring---- Data collection device and industrial PC (or notebook PC) are designed with USB ports, performance are much higher than other printer ports; sampling and data transferring can carry out simultaneously, owing to the advanced hardware.
•   Trigger signal is available at any time to get into sampling process, for background noise is always being monitored.
•   Powerful software---- Windows Operating System supports data sampling in various kinds of seismic working modes (sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, and refraction or reflection survey, etc).
•   Advanced technologies make swift display and fast roll possible---- Channel number to be displayed on the screen is defined by the user, maximum 128 channels; support convenient amplitude balance display and clear static time label line display.
•   Flexible configuration, easily extendable---- Both DOS and WINDOWS are optional.
•   Reasonable configuration---- Featuring shake proof, waterproof and dust proof.
