OVERVIEW
Description
The GL-P2C Seismic Intensity Meter incorporates a high-sensitivity triaxial MEMS accelerometer, featuring an embedded Linux operating system with LAN interface connectivity. It supports network configuration through external 4G wireless routers and boasts built-in 8GB storage for network synchronization. With compact design and low power consumption, this device integrates advanced functionalities including automatic seismic event detection, intensity calculation, and real-time estimation of TC/Pd parameters. Capable of generating continuous waveform data, it automatically transmits earthquake-triggered alerts, intensity measurements, and instrument status via network or SMS, complemented by localized audio alarms. The large-format color LCD screen displays real-time waveforms, operational parameters, and seismic data, making wall-mounted installation effortless.
