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

... The cable consists of four 26 AWG (7x34) silver plated copper wires with PTFE insulation surrounded by a braided shield. The shield jacket is a PTFE tape wrap with a nominal outer diameter of 0.131”. Extending the model 2012's one meter cable is not recommended. If you do decide to connect additional cable, we recommend you check each individual installation for oscillation by tapping the accelerometer and watching the differential output for oscillation in the 20kHz to 50kHz region ...
