Seismic digital accelerometer MTSS-1033A-ND

MTSS-1033A-ND is a seismic digital accelerometer.

The model is designed to measure strong motion, monitor and analyze industrial vibrations both as an accelerometer in seismic alarm systems and as a standalone instrument. 

Three identical compact sensitive elements with an electrodynamic force-balance feedback allow for a precision and high stability. This model is designed for input signals of up to ±3g and has a self-noise level of 130 ng/√Hz at 10 Hz. 

Application notes on using MTSS-1033A-ND to construct real-time monitoring systems for a bridge as an example.
