AMS-PLUS MEMS seismic accelerometer

AMS-PLUS MEMS seismic accelerometer with high sensitivity suitable for any environmental condition and designed for the measurement and study of low intensity accelerations in the range 0-500Hz.

AMS-PLUS models are high-sensitivity sensors designed for seismic purposes and for low-intensity, low-frequency motion studies.
AMS-PLUS offer low noise and higher dynamic range respect to standard AMS.
Accelerometers provide a high level, low impedance output. In most applications, no signal conditioning is required. These sensors use low-noise MEMS to provide low-frequency measurements in the micro-G range.
It is available in single, biaxial or triaxial configuration.
