WZG-24B Engineering Seismograph

Based on WZG-24 engineering seismograph, WZG-24B Engineering Seismograph is developed as a 24bit instrument under Chinese/English version WINDOWS operating system. With years of designing and manufacture experiences, and accepting latest electronic technologies and design ideas, WZG-24B features multi-function, high accuracy, high speed, reliable data and good expandability.

Main Function:

•  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:

•  Fast sampling: 24-bit A/D, minimum Sample interval is 10μs for 3 channels and 50μs for 6 channels
•  Perfectly displaying original signals: amplitude and phase are of high consistency, low distortion, with advanced high-cut wave filter which is better than that for 72dB; original signals are presented once again.
•  High-speed data transferring: data collecting device and industrial PC (or notebook PC) are designed with USB, performance are much higher than other printer ports.
•  Background noises are always being monitored; therefore, trigger signals can be received at any time to trigger sampling.
•  Powerful software: under WINDOWS operating system, collecting software supports various working modes, such as sheared wave velocity testing, surface wave testing, micro-tremor detecting, high-density imaging, reflection and shallow refraction survey.
•  This system adopts advanced graphic technology and screen rolls along very fast; maximum 128 channels of wave can be displayed in one screen; waveform amplitude can be balanced conveniently, etc.
•  Flexible configuration, easily extendable: both DOS and WINDOWS are optional.
•  Reasonable structure design, shakeproof, dustproof and waterproof.
