Triaxial accelerometer SDI 2412

MEMS

DESCRIPTION The Model 2412 is a three axis, open frame accelerometer assembly for use in zero to medium frequency instrumentation applications. It contains three Model 1210 analog capacitive accelerometers orthogonally mounted on a phenolic frame. Overall size is 1.2" x 1.2" x 1.0", weight is 16 grams, and it is easily mounted via two #4 (or M3) screws (not included). An optional calibration test sheet (2412-TST) is also available which lists the measured bias, operating current and frequency response. OPERATION The Model 2412 accelerometer produces three individual analog outputs which can be used either in differential or single ended modes referenced to +2.5 volts. The voltage of each output is proportional to the orthogonal component of the applied acceleration. The Model 2412 operates with a single +5 volt power supply and generates its own +2.5 volt reference with an on-board resistive divider. The three sensitive axes are perpendicular to the bottom of each of the individual accelerometer packages, with positive acceleration defined as a force pushing on the bottom of the package.
