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 +VS and -VS supply 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.
