SHORT PERIOD GL-PS2 SEISMOGRAPHS
GL-PS2 is a state-of-the-art, integrated, and highly portable short-period seismograph meticulously developed to meet the diverse demands of seismic observation in various portable scenarios. This cutting-edge device seamlessly integrates a tri-axial short-period feedback seismometer with a high-performance 24-bit data acquisition system. It’s designed with a compact structure, comprehensive functionality, and remarkable energy efficiency, making it the perfect choice for applications such as portable emergency observation, reservoir earthquake monitoring, scientific array observations, and more.
Description
FREQUENCY RANGE
The GL-PS2 digital seismometer houses a built-in, fully-fledged three-dimensional displacement conversion short-period seismometer with an observation frequency band spanning from 2 seconds to 50 Hz. Its monitoring capabilities are seamlessly integrated into the data acquisition component. The built-in data acquisition unit efficiently handles the extraction, filtering, and real-time calculation of three-channel collected data. It offers users two FIR filter options: minimum phase and linear phase. The collector features an embedded Linux operating system, endowing the GL-PS2 with robust data storage management and data servicing capabilities.
DATA STORAGE AND TIMING
Through the LAN network interface, it supports multi-channel continuous real-time data stream transmission and remote FTP data file downloads. With 8G of built-in memory (expandable), it facilitates the long-term storage of real-time collected data. The time signal input utilizes IRIG-encoded GPS signals and supports NTP network timing functions, ensuring precision and reliability with a synchronization time difference of less than 0.01ms and clock stability better than 0.5ppm.
