MEMS accelerometer
2 - 200 g | SDI 2470
Silicon Designs
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.
OPERATION
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.
