DESCRIPTION
The model 2220 accelerometer is a higher performance and wider temperature range version of the model 2210.
This rugged 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. The cable’s shield is electrically connected to the case while the ground (GND)
wire is isolated from the case. An initial calibration sheet (2220-CAL) is included and periodic calibration checking is
available.
OPERATION
The Model 2220 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 +9 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.
