Inclinometer gets to the point of
sensing
Compact MEMS-based dual-axis inclinometer can be integrated precisely at the point of sensing interest.
Analog Devices has come up with a highly integrated dual-axis inclinometer that makes extremely accurate easy-to-use tilt sensing an affordable and accessible option for industrial equipment manufacturers The ADIS16209 programmable, dual-mode inclinometer sensor is suited to a diverse set of industrial applications that require inclination changes to be measured, including surveying equipment, factory machine tools, satellite antenna stabilisation systems, motion safety monitors and automotive wheel alignment

14bit A/D conversion at 105Msample/s
Analog Devices is claiming another industry breakthrough with the first 14bit ADC to run at 105Msample/s.
Functionally equivalent inclinometer solutions are typically 100 times larger than the ADIS16209.
The industry's most precise MEMS (microelectromechanical systems) inclinometer, the ADIS16209 provides a fully compensated direct angle output with less than 0.1-degree linear inclination error, making it at least twice as accurate as competitive tilt sensors.
This is due to the addition of an embedded controller, which uses factory-installed calibration coefficients to dynamically sense the system environment and compensate the direct-digital angular output to account for changes in voltage, temperature, angle and other variables.

Other MEMS-based tilt sensors typically require industrial engineers to perform additional external calibration and signal processing that adds time, cost and complexity to product design.
ADI's MEMS-based inclinometer is also significantly smaller than alternative sensing technologies, especially bulky, fluid-filled electrolytic sensors, which can require special board mounting.
As a result, the ADIS16209 affords designers the option to more easily integrate the new sensor precisely at the point of sensing interest.
"The ADIS16209 provides an accurate and simple bits-out angle in a standard semiconductor format", says Andy Garner, Product Line Director for iSensor intelligent sensor products, Analog Devices.
"This is a big departure from both electrolytic sensors and less integrated MEMS-based sensors".
"The on-chip dynamic compensation of the ADIS16209 is important for two reasons: it allows our customers to confidently absorb mid-stream system design changes without losing their time to market advantage; and it provides end users with equipment that delivers accurate sensing data that is resistant to in-field environmental changes that can often result in costly, cumbersome recalibration".
The ADIS16209 dual-axis programmable inclinometer, based on an Analog Devices' iMEMS core, is capable of measuring dual-axis tilt with less than 0.1 degrees error across a +/-30-degree range when mounted horizontally.
Because of its unique dual-mode operation, the new sensor also supports a vertically mounted single-axis implementation, over a full 360-degree range.
The tuneable digital sensor data is output via an industry-standard SPI (serial peripheral interface) port, which provides access to inclination (0.025 degree resolution), acceleration (0.244mg resolution), temperature and power supply.
The ADIS16209 also features a 12bit auxiliary ADC input and DAC output, digital self-test function and configurable condition monitoring, including alarms.
The sensor operates on a single 3 to 3.6V power supply and can withstand a 3500g shock.
The ADIS16209 dual-axis programmable inclinometer is sampling now in a 9.2 x 9.2 x 3.9mm laminate-based LGA (land grid array) package.
Production quantities will be available in November 2007.
The ADIS16209 is priced at US $34.40 per unit in 1000-unit quantities.
