CGY-165 projection magnetic compass
Description:
CGY-165 Projection Magnetic Compass is a class A liquid magnetic compass. It is suitable for all types of ships as a standard compass and steering compass, used to indicate the direction of the direction. 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. This overcame the difficulty of the lack of space in the steering room and the difficulty of correcting the compass in the steel window room.
Adopt standard:
GB/T 141083-93《A Class Magnetic compass technology term for shipping》
Application:
Suitable for all types of ships as standard compass and steering compass, used to indicate the direction of the direction.
Features:
1. It has excellent performance and reliable operation；
2. It can be used as a standard magnetic compass and also as a steering magnetic compass；
3. Reducing the area of cab and difficulty of compass adjusting in steel cab；
4. The drawtube can be adjusted up and down and rotated to the left and right, so that facilitate the observation of the course.
5. Adjusting the brightness of projector illumination for clear image of the card whether day or night.
