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.
