DESCRIPTION
The Model 2470 triaxial accelerometer is a high temperature version of our popular 2460 triaxial device. It combines
three orthogonally mounted model 1221L accelerometers in a rugged case for measuring accelerations in
commercial/industrial environments. This module is tailored for zero to medium frequency instrumentation
applications. Its anodized aluminum case is epoxy sealed and is easily mounted via two #8 (or M4) screws. On-board
voltage regulation and an internal voltage reference eliminate the need for precision power supplies. It is relatively
insensitive to temperature changes and gradients. An initial calibration sheet (2470-CAL) is included and periodic
calibration checking is also available.

OUTPUT VOLTAGE
The Model 2470 produces three differential analog output
voltage pairs (AON & AOP), which vary with acceleration as
shown in the figure (at right). 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 +8 to +32 volts. At zero acceleration the
output differential voltage is nominally 0 volts DC; at ±full
scale acceleration, the output is ±4 volts DC respectively.
The axis directions are marked on the case with positive
acceleration defined as acceleration in the direction of the
axis arrow.
