Projection magnetic compass

 

 

Introduction:

 
 
The projection magnetic compass is specially suitable for various kinds of large and medium merchant ships & naval service vessles to indicate the heading and determine the azimuth. With the help of an excellent optical projection system,the operator can easily and precisely observe the ship's heading in wheelhouse.
It can be conveniently mounted on the compass desk(the top of wheelhouse),the optical cylinder within the binnacle can stretch into the wheelhouse through the base of binnacle.Partial image of the car of compass bowl can be displayed on the plane mirror at the end of the optical cylinder.
The compass is designed to meet the technical requirements of GB/T14108-93 and ISO-449 standards referring Class A magnetic compass.

 
 
Characteristics:

 
 
Good in performance and high in reliablility.
Used as a standard compass, also a steering compass.
Optical cylinder can be adjusted along with its axis and rotated about its axis,then conveniently observed by operator.
Illumination projection system can be adjusted in wheelhouse.
On the glass of the compass bowl is mounted a location block on which can be mounted various sensors for interfacing with an autopilot.
