INDUSTRIAL AND TEST & MEASUREMENT
MEMS DC ACCELEROMETER MODULES
All SDI Industrial and Test & Measurement MEMS DC Accelerometer Modules incorporate the company's own highly rugged, low-noise surface mount accelerometer chips for precise and dependable full-scale measurements ranging from ±2g to ±400g. This feature makes the modules suitable for use in most low-to-medium frequency applications, and with measurement accuracy down to DC (0 Hz). Internal amplifiers and power regulation eliminate the need for extra equipment. Each unit undergoes 100% factory testing and calibration prior to factory shipment.
