Sensor monitors height and orientation

A McLennan Servo Supplies product story
Edited by the Engineeringtalk editorial team Sep 5, 2007

Tamagawa's new sensor provides attitude angle measurement in pitch to +/- 90 degrees and roll/yaw to +/- 180 degrees with accuracy of +/- 0.5 degrees.

Tamagawa has released a low-cost attitude measurement system for dynamic pitch, yaw and roll, angular rate and acceleration performance testing on vehicles and motion simulation systems.

The system is comprised of the TA7546 fibre optic gyro sensor unit connected via a dedicated serial port to the separate TA7576 controller unit, which features twelve +/- 5V analogue outputs with a 200kHz refresh rate, a time/mark signal input, a car speed input and an angle reset input.

The analogue outputs provide attitude angle measurement in pitch to +/- 90 degrees and roll/yaw to +/- 180 degrees with accuracy to +/- 0.5 degrees.

X,Y, Z angular rate is measured to +/- 100 degrees per second, and X,Y,Z acceleration up to 49m/s2 - all within a 0.2% full-scale accuracy.

Although aimed predominantly at the dynamic road vehicle testing industry, the attitude measurement system is also suited to other test and calibration applications in motion simulation, wind tunnel testing, and the amusement ride markets.

The fibre optic gyro sensor unit has also been used on a remotely piloted helicopter application designed for use in hazardous earthquake and geological studies.
