The FAS-A® Inclinometer is designed to provide 1 and 2-axis static and quasi-dynamic orientation measurements. It incorporates 3 accelerometers together with an on-board microprocessor, embedded software algorithm, non-volatile memory for configuration, and serial communication interface. Its form-factor, rated temperature range and power supply requirements are optimized for a broad array of applications. The FAS-A® outputs either one 360° roll axis or two +/-70° pitch and roll axes.

Software
The FAS-A is operated by a combination RS-232 communication and power cable, part number 6208-0020.
The FAS-A analog out port uses an analog cable with flying leads, part number 6208-0010.
From time to time the inertial sensor may need recalibration.
Example: If the inertial sensor contains magnetometers, coming in contact with magnetic influences (magnets, motors, etc.) may cause residual magnetism to be picked up by the on-board components which alter the calibration. In these cases, the inertial sensor should be returned to the factory for recalibration.
Example: The inertial sensor receives a severe shock, slightly altering the position of the circuit boards in relation to the enclosure, again altering the calibration. In these cases, the unit should be returned to the factory for recalibration.
Yes. The FAS-A comes with an analog output cable and will output its pitch and roll measurements as a linearly proportional voltage (0 to 4.096 volts full scale).
The sensor can output pitch and roll.
Yes. A Windows XP/Vista/7 compatible software is shipped the product. The software allows the user to configure, operate, display and save data from the sensor.
Yes. A complete data communications protocol manual and sample code is shipped with the sensor.
The FAS-A can measure static and quasi-dynamic rotations with an accuracy of +/-0.7 degrees typical.
The FAS-A can measure 360 degrees in single axis mode and +/-70 degrees in dual axis mode.
