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.
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.
