DESCRIPTION
The model 2010 single axis accelerometer module is designed to be used with the
model 3020 G-LOGGER
TM Acceleration Acquisition System.
Up to three 2010's
may be connected to a G-LOGGER
TM
using a model 3901 Cable Adapter. The
2010 contains a model 1010L accelerometer which features a micromachined
capacitive sense element, a custom integrated circuit sense amplifier, and sigma-
delta A/D converter.
It provides a TTL/CMOS compatible output signal for
measuring accelerations in commercial/industrial environments and 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. It is
relatively insensitive to temperature changes and gradients. An optional calibration
sheet (2010-CAL) and periodic calibration checking are available.
OPERATION
The model 2010 accelerometer produces a digital pulse
train in which the density of pulses (number of pulses per
second) is proportional to applied acceleration. It requires
a single +5VDC power supply and a TTL/CMOS level clock
of 100kHz-1MHz. The output is ratiometric to the clock
frequency and independent of the power supply voltage.
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. External digital line
drivers can be used to drive long cables or when used in
an electrically noisy environment.
SIGNALS
