The SE2404NTN series sei***ic data acquisition system is a portable wired telemetry sei***ic data acquisition system. This system uses advanced networking technology for distributed real-time data acquisition and display. The system is composed of the SE2404NTN main control unit, a data acquisition station (RSU), a central hub (CSU), digital tran***ission composite cables, and remote detonation decoder. It can be widely applied wherever high precision two or three dimensional sei***ic surveying is required, such as surveying for engineering, coal, minerals, and/or hydroelectric power.
Main Properties
1. Using networking and control technology, the system can be extended with up to 2048 sensor modules.
2. The main control unit is equipped with two data flow ports and built-in remote detonation encoder.
3. Real time data display, storage, and playback.
4. Data acquisition modules use true 24 bit high precision analog to digital converters and open addressing technology, and h***e large dynamic ranges, low power c***umption, and are easy to use.
5. Data acquisition modules each has 12 channels, a water-proof cast-aluminum shell, and are ***all, lightweight and easy to maintain.
6. The central hub has a 10Mbps tran***ission speed and can support up to 256 modules, and is ***all, lightweight and easy to maintain.
7. The tran***ission range between the remote control encoder and decoder is 10 km on open ground. The system uses a safety protocol to raise its reliability and safety. The design includes two high precision auxiliary channels.
8. The system is developed using Windows, field usage is simple and quick. The system is designed for both oil surveying sei***ic technology and engineering sei***ic surveying.
