DESCRIPTION
The model 2266 accelerometer module combines an integrated model 1221L accelerometer with high drive, low
impedance buffering for measuring acceleration in commercial/industrial environments. It is tailored for zero to
medium frequency instrumentation applications. The anodized aluminum case is epoxy sealed and is easily
mounted via two #4 (or M3) screws. On-board regulation is provided to minimize the effects of supply voltage
variation. It is relatively insensitive to temperature changes and gradients. A removable cable 2266-CAB attaches
via a 5-pin connector. An optional initial calibration sheet (2266-CAL) and periodic calibration checking are also
available.
OPERATION
The Model 2266 accelerometer module produces two analog voltage outputs, which vary with acceleration as shown
in the graph on the next page. The sensitive axis is perpendicular to the bottom of the package, with positive
acceleration defined as a force pushing on the bottom of the package. 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 differential voltage is ±4 volts DC respectively.
