Portable Centralized 48 Channel High Resolution Seismograph geophone equipment

The digital engineering seismograph is a true 24-digit digital seismograph developed by Shanghai Weiqi Equipment Technology Co., Ltd. and works under the Chinese and English Win10 and Win7 system platforms. It adopts the advanced electronic technology and design concept at home and abroad, and combines the usage habits of many domestic users to design a multi-functional, high-precision, high-speed, high-reliability, with a good human-computer interaction interface and expandable A leading domestic seismograph. The instrument can use hammering, falling weight, electric spark, detonator (explosive) explosion, etc. as the excitation source, and the exploration depth can reach thousands of meters. The field exploration methods include: reflection exploration, refraction exploration, surface wave (Rayleigh wave) exploration, Seismic exploration methods such as multi-wave seismic image exploration, ground pulsation (conventional micro-motion) measurement, building and site vibration safety assessment, foundation pile detection, cross-hole tomography (CT) measurement, and borehole shear wave measurement are widely used in transportation Engineering geological exploration in the fields of hydropower, road and bridge, urban construction, etc. It is also suitable for resource exploration in the fields of oil and gas, coal fields, minerals, and groundwater.

The main function:

A----Reflection exploration: analysis of geological structures such as shallow water surface, bedrock buried depth, geological layer, fracture cavity, etc.

B----Refraction exploration: bedrock burial depth and shape trend analysis, etc.

C---- Surface wave exploration: overburden stratification, roadbed, embankment, slope disease investigation, etc.

D----Multi-wave seismic imaging: foundation, subgrade survey, cave survey, etc.

E----Site fretting measurement: vibration monitoring of sites and work areas and analysis of safety evaluation parameters

F----Foundation pile detection: bridge piers and building pile foundation detection, etc.

G----Blasting measurement: safety assessment of various blasting vibrations on sites and buildings, etc.

H----Cross-bore CT: detection of underground structures, karst and other geological structures

l----Shear wave measurement: measurement of elastic parameters of underground geological rock mass, etc.

1--It can continuously monitor and sample without leakage.

2--12 channels of integers can be cascaded for expansion.

3--The full-frequency noise is constantly monitored, and the collected data is more real and effective.

4--Using high-speed, high-precision true 24-bit A/D converter, the sampling rate reaches 10us when 48 channels are sampled at the same time.

5--Built-in large-capacity lithium battery, 48 channels can work continuously for more than 20 hours without external power supply.

6--Matching with the company's coverage switch can make field exploration more convenient and greatly improve the efficiency of field work.

7--Built-in detection system of the instrument: self-check noise, crosstalk, consistency and other items, and self-test report is automatically generated.

8--It adopts advanced filters with ultra-low distortion and out-of-band suppression, and also has various digital filters in the software.

9--New appearance structure design, hand-held tablet operation, WIFI communication, the longest distance can reach 100 meters, convenient and fast.

10--Built-in coverage measurement function: SDZ-48A and SDZ-24A can support 24-channel and 12-channel coverage measurement without adding external configuration.

11--Data storage files are in standard Seg2 and SegY formats, which support various processing software at home and abroad, and can be saved in text format, which is convenient for users to process data by themselves.
