DESCRIPTION
The P-Cap_TM model 2260 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 thermal gradients. The cable’s shield is electrically connected to
the case while the ground (GND) wire is isolated from the case. An optional initial calibration sheet (2260-CAL) and
periodic calibration checking are also available.
OPERATION
The P-Cap_TM Model 2260 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.
