OVERVIEW
Description
The GL-P2A incorporates a high-sensitivity triaxial MEMS accelerometer module. Its data acquisition unit is a compact version of the EDAS-24GN, sharing identical designs in ADCs and ARM9-based Linux-embedded systems. With ±2.0g measurement range and DC-100Hz bandwidth, it features a built-in 10-year maintenance-free supercapacitor that sustains operation for over 3 minutes during grid failures. Notable for its compact dimensions (22cm×15cm×11cm) and lightweight design (4kg), the GL-P2A offers easy installation, making it ideal for seismic platform network deployment, structural monitoring, blasting effect evaluation, site safety assessment, and vibration measurements in critical infrastructure including reservoirs, dams, bridges, stations, and tunnels.
