Product overview
The BWSENSING BW-320A is a medium-accuracy digital closed-loop fiber-optic gyroscope for single-axis measurement. Its intended roles include airborne navigation, payload attitude determination, and positioning and orientation systems for unmanned aircraft, ships and land applications. The physical architecture combines optical and electronic elements in an integrated package, using an all-solid-state structure without rotating components. This configuration provides a compact sensing component for integration into those systems, with vibration resistance and magnetic-field resistance among its design characteristics.
Integration requires space for dimensions of ≤59.6mm×59.6mm×26.3mm, a mass allowance of ≤150g, and four φ4.2mm mounting points. The electrical configuration uses +5VDC, consumes ≤4W and provides an RS422 interface that can be customized. Measurement range is ±530º/s, with bias stability of ≤0.1º/h at 1σ over 10s. Operating limits include -45℃ to +70℃, vibration withstand of 18g, and shock withstand of 100g for a 6ms half-sine pulse. Storage temperature extends from -55℃ to +85℃.
