GL-PA4: ACCELEROGRAPH WITH TRIAXIAL FORCE-BALANCE ACCELEROMETERS

TRIAXIAL ACCELEROGRAPH WITH FBA

GL-PA4: Your Comprehensive Seismic Observation Solution. With functionalities spanning acceleration sensing, data acquisition, storage, transmission, and detection, GL-PA4 is engineered for precision and efficiency.

At the heart of GL-PA4 lies a sophisticated assembly: a 24-bit ADC, force balance accelerometer (FBA), data storage module, network communication interface, and a GPS timing clock. Central to its design, the FBA captures vibration acceleration signals across three distinct axes - north-south, east-west, and vertical.

The in-built ADC is characterized by three balanced differential channels, delivering high resolution and an expansive dynamic range. This ensures rapid, real-time data streaming with unmatched timing precision. Moreover, its network capabilities enable diverse sampling, with a dynamic range hitting its zenith at 138dB at 50 samples-per-second (sps).

Data Storage & Advanced Sampling

GL-PA4 is designed for longevity. Its spacious, industrial-grade CF card memory—optimized for a wide temperature range—can archive continuous, event-driven, and calibration data over prolonged durations. Notably, for meticulous recording of significant earthquake calibrations, it operates at a sampling prowess of 500 sps. Additionally, data from varied sampling frequencies can be seamlessly relayed to the central network in real-time.

Design Excellence

Our commitment to excellence is evident in its form factor. This triaxial accelerograph is an epitome of engineering finesse—compact, lightweight, and optimized for minimal energy consumption.
