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 (3mm) screws (not included).

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.

PERFORMANCE

Operating current is three times the current specified on the Model 1210 data sheet.  Bias Calibration Error is derated from the Model 1210 accelerometer to 1.5% typical and 3% max.  For all other performance data, absolute maximum ratings and detailed descriptions of the AOP, AON, and DV signals, please refer to Silicon Designs' Model 1210 data sheet.

Mounts using two #4 or 3mm screws.
Connection is via standard ribbon cable (0.050" centers) and connector (0.100" centers).
