INDUSTRIAL TEST & MEASUREMENT
MEMS DC ACCELEROMETER MODULES

All of SDI's Industrial Test & Measurement Accelerometer Modules contain its highly-rugged, low noise surface mount accelerometers for accurate and reliable full scale measurement from ± 2g to ± 400g.  The MEMS capacitive accelerometers make them ideal for low-to-medium frequency applications, and all of them can measure down to DC (zero hertz ).  Internal amplifiers and power regulation eliminate the need for extra equipment, and every unit is individually tested and fully calibrated.
