Analog Devices’ ADIS16209 is a highly integrated, dual-axis inclinometer that makes extremely accurate, easy-to-use tilt sensing an affordable and accessible option for industrial equipment manufacturers. This 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 stabilization systems, motion safety monitors and automotive wheel alignment. Functionally equivalent inclinometer solutions are typically 100 times larger than the ADIS16209.

The ADIS16209 provides a fully compensated direct angle output with less than 0.1 ° linear inclination error. 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.

The device operates across a ±30 ° 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 ° range. The tunable digital sensor data is output via an industry-standard SPI port, which provides access to inclination (0.025 ° resolution), acceleration (0.244 mg resolution), device temperature and power supply. The ADIS16209 also features a 12-bit auxiliary ADC input and DAC output, digital self-test function and configurable condition monitoring, including alarms. The sensor operates on a single 3 V to 3.6 V power supply, and can withstand a shock of 3500 g.

The ADIS16209 dual-axis programmable inclinometer is sampling now in a 9.2 mm × 9.2 mm × 3.9 mm laminate-based land-grid-array (LGA) package. Pricing is $34.40 per unit in 1000-unit quantities.
