MD54 ADHESIVE MOUNT for COMPASS SENSOR

MODEL NUMBER: MD54

The MD54 is a non-ferrous mounting for attaching the MARINE DATA MD52A series of ship’s magnetic compass sensors to a ship’s magnetic compass.

SKU: F054001 Category:

Product Description

OVERVIEW

The MD54 Adhesive Mount attaches a ship’s magnetic compass sensor to an existing ship’s magnetic compass as part of a Transmitting Magnetic Compass System. The MD54 is designed to adhere to the smooth concentric area located underneath most externally gimballed ship’s magnetic compasses.

Note: A compass sensor should not be glued directly to a host compass. Performance may be reduced, maintenance made difficult or the compass sensor could even become damaged. The MD54 Adhesive Mount eliminates all these issues.

For ship’s compasses where the MD54 Adhesive Mount cannot be fitted, we recommend our MD58 Bracket Mount.

Once correctly mounted, the MARINE DATA MD52A Compass Sensor can detect and send the magnetic compass heading for signal processing before being transmitted as NMEA 0183 data to other equipment, for example, in a Transmitting Heading Device (THD) System.

The MD54 Adhesive Mount from MARINE DATA: easy to install and simple to maintain.

INSTALLATION GUIDE

  • To prevent errors when mounted, the sensor must be parallel and concentric with the compass card.
  • When fitting the mounting, height adjustment may be required. Mountings of different thicknesses are available from MARINE DATA; contact us for information. To find the correct height position, use a small needle compass placed concentrically with the compass card. Determine the vertical null point; this is the point at which the compass card has no effect. The sensor must be placed midway between this point and the compass card. On a typical compass card of 2000 CGS this is approximately 60 – 90 mm from the card. If the sensor is mounted too close, an error may be induced in the compass card reading. To check there is no error once mounted, ensure that there is no measurable difference in the compass heading when the sensor is on or off. If the sensor is mounted too far away then the field strength between the compass card and sensor will not be strong enough and the reading device will be inaccurate.
  • The sensor must be positioned on the compass such that if a reflector is fitted, the sensor does not obscure the viewing of the compass card.
  • Compass Correction: Provided the nearest corrector magnet does not have a distance ratio between sensor and compass card of more than 1.2:1.0, accuracy should not be affected.
