C G Y - 1 6 5 投影磁罗经 CGY-165 Projection Magnetic Compass
CGY-165投影磁罗经是根据磁罗经国家标准GB/T 141083-93《船用A级磁罗经通用技术条件》设计制造的，适用于各种类型的 船舶上指示方位和航向。磁罗经安装在驾驶室顶，罗经柜中的镜筒（光学投影装置）由罗经柜基座下方伸入驾驶室内，在镜筒端部的平面反射镜上显示出罗盆度盘的部分扇型影像。
CGY-165 Projection Magnetic Compass is designed and manufactured by Standard GB/T 141083-93《A Class Magnetic compass technology term for shipping》.It canshow the direction and the vessels position in shipping. The Magnetic Compass installs on the top of cab.The binnacle’s drawtube extends into cab by the bottom of foundation.The plane mirror of drawtube reflects partial fan-shaped image of compass bowl ferry.
Primary Characteristic:
(1) Using as standard compass or steering compass. Reducing the area of cab and difficulty of compass adjusting in steel cab.
(2) In order for convenient observation to adjust the drawtube up and down and circumvolve it right and left.
(3) Adjusting the brightness of projector illumination for clear image of the card whether day or night.
