High temperature dual axis accelerometer
sensor for rugged apps
Analog Devices, Inc. has made available the ADXL206 high
precision, low power, dual-axis iMEMS accelerometer with
signal conditioned analog voltage outputs. The single-chip
ADXL206 measures acceleration with a full-scale range of
±5 g and measures both dynamic acceleration such
as tilt and static acceleration such as gravity. ADI says
ADXL206 offers a guaranteed operating temperature range
of -40° C to +175° C and excellent overall stability,
and is designed for geological down hole tools and other
extreme high temperature industrial applications.
"Instead of using additional temperature compensation
circuitry, innovative design techniques have been used to
ensure that high performance is built in," said Wayne
Meyer, marketing and applications manager, MEMS/Sensors
Technology Group, Analog Devices. "As a result, there
is essentially no quantization error or non-monotonic behavior,
and temperature hysteresis is very low, typically less than
2 mg over the entire -40° C to +175° C temperature
range. This is another example of ADI's high performance
MEMS inertial sensor leadership."
"As designers put together smart drilling systems
that go miles and miles under the earth's surface, they
are challenged to balance power and space requirements against
the need for more information," said Pam Aparo, segment
marketing manager for Instrumentation, Analog Devices. "The
ADXL206 iMEMS accelerometer is not only an extremely compact
solution, but it also lowers power consumption by an order
of magnitude from over 10 mA to under 0.5 mA per axis."
The ADXL206 iMEMS accelerometer has a typical noise floor
of 110 µg/vHz, allowing signals below 1 mg (0.06°
of inclination) to be resolved in tilt sensing applications
using narrow bandwidths (<60 Hz). Bandwidths of 0.5 Hz
to 2.5 kHz can be selected to suit the application. The
ADXL206 is available in a 13 mm × 8 mm × 2 mm,
8-lead, SBDIP (side-brazed ceramic dual in-line package)
package.
