DESCRIPTION

The Model 2012 accelerometer module provides a rugged protective case around

an integrated model 1210L accelerometer for measuring accelerations in

commercial/industrial environments. It is tailored for zero to medium frequency

instrumentation applications. The anodized aluminum case is epoxy sealed and

is easily mounted via two #4 (or M3) screws.

to the case while the ground (

Please refer to the Model 2210 for applications that require a lower output

impedance or greater power supply rejection ratio than the Model 2012 provides.

OPERATION

The Model 2012 accelerometer module produces two

analog voltage outputs, AOP & AON, which vary with

acceleration as shown in the graph at right. The signal

outputs are fully differential about a common mode

voltage of ½ V

acceleration, the output differential voltage is nominally

zero volts;

differential voltage is +4 volts; at -full scale acceleration

the output differential voltage is -4 volts. 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.

SIGNAL DESCRIPTIONS

and ground.

AOP and AON (Output): Green & white wires respectively. 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 pair can be used differentially
