Marine Projector Magnetic Compass
Description:
A marine projector magnetic compass is a navigational instrument that is commonly used on larger boats and ships to determine the direction of travel. It is called a projector compass because it projects the readings of the compass onto a screen for easy viewing and interpretation by the navigator. The marine projector magnetic compass typically consists of a circular card with markings indicating the cardinal and intermediate directions. The card is mounted on a pivot or bearing that allows it to rotate freely. A magnetized needle or bar is attached to the center of the card and aligns itself with the Earth's magnetic field, indicating the direction of magnetic north. The housing or bowl of the compass is typically made of brass or other non-magnetic materials to reduce interference with the magnetic field. It is filled with a liquid, such as oil, which helps to dampen any movements of the card and needle, and provides stability and accuracy of the readings. The projector system consists of a light source and a lens that projects an enlarged image of the compass card onto a screen or display panel. This makes it easier for the navigator to read and interpret the compass readings, especially in low light or poor visibility conditions. Marine projector magnetic compasses may also be equipped with additional features, such as automatic deviation compensation, which adjusts the readings to account for any magnetic interference from the boat or ship's equipment. They may also be mounted on a gimbal or other stabilization system to keep the compass level and accurate even in rough seas.
Features:
The projector magnetic compass is a kind of vertical magnetic compass. It uses the projection principle of the projection device to feed the information from the magnetic compass dial back to the steering room. The projected magnetic compass combines the ship's standard compass and steering compass into one, which not only saves cabin space, but also solves the problem of inconsistent readings between the steering compass and the standard compass.
Adopt standard:
ISO 449, IMO
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
Advantages:
1. The product has the characteristics of high precision and stable performance, and can be used for a long time in the bad condition of the ship.
2. As a standard magnetic compass and steering magnetic compass, it overcomes the difficulty of the lack of cockpit area and the difficulty of calibration in the cabin.
