System Ready, Fully Integrated, and Calibrated Inertial Sensors Bring Affordable Motion Sensing to Industrial Control

mplementing motion sensing into industrial control applications has long been a challenging design hurdle. Design engineers are faced with complex interface considerations and the need for precision motion testing for calibration—leading to lengthy design-in cycles. While the added system benefits from motion sensors are numerous, the typical industrial customer has not always been able to justify the added expense, time, and risk involved in implementing them.

ADI's family of iSensor™ products simplifies integration and opens up the myriad benefits of MEMS sensors to everyone. With precision outputs, standard interfaces, and simple programming options, motion analysis and control can be added to your system design with iSensor by simply supplying power and a serial interface. With factory-calibrated outputs, these products eliminate the need for special application tests and motion calibration equipment. They are easily in-system tunable to provide the best accuracy and stability across a wide range of application requirements.

Detecting and controlling angular rate motion in industrial machinery and instrumentation has been simplified with the introduction of ADI's iSensor gyros. For single-axis solutions, the temperature-calibrated ADIS16255 provides in-run bias stability of 0.016°/sec, and a temperature coefficient of 0.005°/sec/°C. With an SPI port and programmable interface, it is the most stable, compact, and simple to use gyro available today. This performance is extended to triple-axis capability in the new ADIS16350, which is a six-degree-of-freedom sensor, in a form factor less than 1" cubed. The seven internal sensors (including temperature) are calibrated, cross-compensated, and precision aligned to correct for all significant electrical, positional, and motion influences. The ADIS16350 is at least 30% smaller than any existing approaches, and 5× to 10× less costly.
