The SM1500 & SM550 Strong Motion Acceleration Sensors

3-axis accelerometers Ultra Low Power Consumption Surface mounting MEMS technology DC – 1500Hz BW Wide Dynamic Range 117dB Output range +/-3g linear Noise level 0.3ugrms?Hz Operating temperature -20 to +70oC Borehole type (optional)

The SM550 and SM1500 are two MEMS type, three-component acceleration equivalent output sensor. Both have wide frequency response. Model SM1500 has a response from DC to 1500Hz, while the SM550 model has a response from 0.5 to 550Hz. Output Range is +/-3g for the horizontal axes, and +/-2g for the vertical axes. Sensitivity is 1.2V/g for the Sm1500, and 0.3V/g for the SM550 model.

The SM1500 sensor operates from a bipolar power supply that can range from +/-6V to +/-15V with a typical power consumption of 33mA @6Vdc

The SM550 sensor operates from a  unipolar power supply that can range from +/-9V to +/-20V with a typical power consumption of 16mA @9V

The default cable length between the sensor and the digitizer is approximately 2 meters but it can be extended up to 50 meters.
The sensors are surface mounted, over a provided special base, giving the ability for leveling.
