Portable Integrated Seismic Recorder & MEMS Accelerometer 

The SMA2 combines Reftek's latest generation of universal broadband seismic recorders, with the advanced high-resolution, capacitive accelerometer, model 131D. Designed to facilitate installation, security and maintenance in a single, secure enclosure optimized for structural monitoring applications.

The SMA2 features a high-performance A/D and boasts a wide dynamic range. The dynamic range enables the SMA2 to record very small vibrations from its integrated seismic sensor, providing detailed data for seismic analysis.

The internal triaxial accelerometer is a capacitive MEMS accelerometer that converts acceleration signals into voltage signals to measure low-frequency and ultra-low-frequency motion. It features high sensitivity, a large 600 Hz linear range, high resolution, and wide dynamic range making it perfectly suited for structural monitoring applications.
