Force Balanced Accelerometer
Model EA-140
The EA-140 occupies the high-end range of the Servo Force Balance Accelerometer line. It offers very low noise, high dynamic range, in a frequency band of DC to 50 Hz. It is suited for specialized strong motion monitoring applications.
The EA-140 standard packaging is an open-ended 3 1/4 inch plate that can be mounted internally in the SMR recorder or the R-1 Triaxial Rotational Sensor. Optional freestanding field or borehole packages are available.
The sensor elements are housed in an epoxy sealed aluminum case. They are extremely rugged, and designed for long-term deployment in field environments. Unlike solid-state type accelerometers, the EA-140 does not experience significant drifting with temperature changes.
Options include a variety of full-scale "g" levels, user selectable full-scale "g" ranges, and other frequency bands
