Model EV-12
The EV-12 is a high sensitivity uniaxial force balance sensor with both velocity and acceleration outputs.
Unlike piezo type sensors, the servo force balance construction offers acceleration frequency to DC. The velocity output has a frequency range of 0.5Hz to 70Hz. It offers low noise, high dynamic range, and is perfectly suited for most strong motion monitoring applications.The unit can be used either as in horizontal or vertical orientations*.
The EV-12 standard packaging is a small 2-inch cube field case with mounting plate and connector. 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 EV-12 does not experience significant drifting with temperature changes.
Options include a single side voltage input with differential output for long sensor run applications.
