DESCRIPTION

The Model 2210 accelerometer module combines an integrated Model 1210L accelerometer with high drive, low impedance buffering for measuring acceleration in commercial/industrial environments.  It is tailored for zero to medium frequency instrumentation applications.  The module contains a miniature, hermetically sealed micromachined capacitive sense element, a custom integrated circuit sense amplifier, and differential output stages.  The anodized aluminum case is epoxy sealed and is easily mounted via two #4 screws.  On-board regulation is provided to minimize the effects of supply voltage variation.  It is relatively insensitive to temperature changes and gradients.  The cable shield is electrically connected to the anodized aluminum package.  An optional initial calibration sheet (2210-CAL) and periodic calibration checking are also available.

OPERATION

The Model 2210 accelerometer module produces two analog voltage outputs which vary with acceleration as shown.  The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as a force pushing on the bottom of the package. The signal outputs are fully differential about a common mode voltage of approximately 2.5 volts. The output scale factor is independent from the supply voltage of +9 to +30 volts.  At zero acceleration the output differential voltage is nominally 0 volts DC; at ±full scale acceleration the output differential voltage is ±4 volts DC respectively.

SIGNAL DESCRIPTIONS

VS and GND (Power): Red and Black wires respectively.  Power (+9 to +30 Volts DC) and ground.

AOP and AON (Output): Green and White wires respectively.  Analog output voltages proportional to acceleration; AOP voltage increases (AON decreases) with positive acceleration.  At zero acceleration both outputs are nominally equal to 2.5 volts.  The device experiences positive (+1g) acceleration with its lid facing up in the Earth's gravitational field.  Either output can be used individually or the two outputs can be used differentially. (See output response plot above)
