Shallow Transient Surface Wave Tester Used in Engineering Inspection

About Product

Product Introduction

WZG-6 is developed based on WZG-24 engineering seismograph which is Chinese WINDOWS based and 24-bit. It embodies not only the seismograph design experiences of our institute, but also the modern electronic technique and design ideals. It is of multi-function, high-precision, high-speed, high-reliability and fine expansibility. It is truly a refined one of all kinds of seismographs.
Industrial computer or laptop computer is required for operation through simple connection of USB port. Built-in rechargeable battery can ensure more than 8 hours work. Seismic source can be hammer, electric spark or dynamite, so that it is fitted for surface wave exploration, shear wave velocity test,pier test, earth vibration measurement, seismic imaging, shake measurement, refraction or reflection survey. It is extensively applied in engineering exploration, such as irrigation works, power, railway, bridge, civil construction, traffic, etc.. It can also be used in ground water and energy exploration, such as petroleum, coal, and uranium.

Main Functions

1. Transient multi-channel surface wave (Rayleigh wave) exploration 
2. Shear wave velocity measurement 
3. Pier inspection 
4. Construction quality inspection 
5. Multi-component high-density seismic imaging 
6. Shake blow up measurement 
7. Field long-term jiggle measurement 
8. Shallow refraction and reflection

Technical Specification

Main Specifications

1. True 24-bit A/D- fastest sampling rate is 10μs and 50μs for 3 or 6 channels operation. 
2. Perfect display of raw signal- Fine amplitude and phase consistency, super-low Distortion, advanced high-cut filter above 72dB (cut point changeable as sampling frequency, complete delete the possibility of false frequency). 
3. High-speed data transfer- fast USB port connection between device and computer, good performance above other printer ports, unique in China; sampling and transferring simultaneously with advanced hardware. 
4. Momentarily acceptable of trigger signal for sampling during background signal monitoring. 
5. Powerful software- WINDOWS version supports each kinds of seismic working modes data sampling (such as surface wave test, shear wave velocity testing, earth vibration measurement, high density imaging, refraction and shallow reflection). Advanced technique makes the display and scroll very fast; adjustable channel number, maximum 128; convenient amplitude balance display; clear static time ticks. 
6. Flexible configuration, easily extendable-DOS and WINDOWS Version optional. 
7. Reasonable structure layout- anti-quake, anti-humidity, anti-dust.
