DESCRIPTION

The Model 2440 triaxial accelerometer is a higher performance and wider

temperature range version of the model 2430. It combines three orthogonally

mounted Model 1221L accelerometers, in a rugged case for measuring

accelerations in commercial and industrial environments. This low noise module

istailoredforzerotomedium frequencyinstrumentationapplications. Theanodized

aluminum case is epoxy sealed and is easily mounted via two #8 (or M4) screws.

The design includes an instrumentation amplifier on each axis providing high drive

capability and low output impedance. On-board voltage regulation and an internal voltage reference eliminate the

need for precision power supplies. No power supplycurrent flows through the OUTPUT REF wire; this high impedance

input is used only as a reference for the acceleration outputs which reduces cross talk among the three channels by

rejecting noise from voltage differences between the user's data acquisition equipment and power supply grounds.

The 2440 is relatively insensitive to temperature changes and gradients. An initial calibration sheet (2440-CAL) is

included and periodic calibration checking is available.

OPERATION

The Model 2440 produces three analog voltage outputs

which vary with acceleration. The Z axis is perpendicular

to the bottom of the package, with positive acceleration

defined as a force pushing on the bottom of the package.

The X and Y axis directions are marked on the cover with

positive acceleration defined as acceleration in the

direction of the axis arrow. The outputs are single ended

and vary with respect to the voltage at the OUTPUT REF

input which should be approximately centered between

the +V_Sand -V_Ssupply voltages. The output scale factor

is independent of the supply voltages from 12 to 16

volts. At zero acceleration, the output voltage isnominally

zero volts; at full scale acceleration the output voltage

is 5 volts respectively.
