It is tailored for zero to medium frequency instrumentation applications. The anodized aluminum case is epoxy sealed and is easily mounted via two #8 (or M4) screws. It is relatively insensitive to temperature changes and gradients. An optional initial calibration sheet (2422-CAL) and periodic calibration checking are also available. OPERATION The Model 2422 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 ratiometric to the applied VDD voltage and at zero acceleration, both AON & AOP are equal to halfway between VDD and GND. The axis directions are marked on the case with positive acceleration defined as acceleration in the direction of the axis arrow.
