MD97TMC Transmitting Magnetic Compass System – Simplified

Simplified Transmitting Magnetic Compass System: Accurate magnetic heading from a ship’s magnetic compass is transmitted to a remote heading repeater display over a digital NMEA 0183 connection

SKU: F097100 Categories: ,

OVERVIEW – Simplified Transmitting Magnetic Compass System

Increasingly, Maritime Authorities are accepting the use of Transmitting Heading Device (THD) Systems on board vessels. Instead of using inflexible and bulky optical apparatus (reflectors, periscopes etc.) to view the magnetic compass, an electronic remote display may be used.

The MARINE DATA MD97TMC is a Transmitting Magnetic Compass (TMC) System which detects and transmits the ship’s Compass Heading over a NMEA 0183 digital connection to one or more Heading Repeaters (Compass Repeaters) at any convenient location on a vessel.

The Calibration Control and Sensor Processor is used to calibrate the Compass Sensor by turning the ship through 390°. The latest technology accurately processes and converts compass card position to NMEA 0183 Heading Data.

The MARINE DATA™ MD97TMC Transmitting Magnetic Compass System is simple and intuitive to use with quick and easy installation.

SPECIAL FEATURES

  • Simplified system design with just two main components
  • Easy calibration of Magnetic Sensor Coil with host ship’s magnetic compass
  • Simple installation procedure
  • Provides two NMEA 0183 outputs
  • Optionally connects with the MD71THD Control and Display Unit, which provides calibration control, allows variation correction and adds heading display functionality at a convenient location on the vessel (available as an option)

APPLICATIONS

  • Provides 2 digital NMEA heading outputs to drive Heading Repeaters (or other devices) at a convenient location
  • An elegant alternative to using an optical reflector in a ship’s magnetic compass installation

RELATED PRODUCTS

  • The full range of MARINE DATA Heading Repeaters

PARTS INCLUDED IN THIS TMC SYSTEM

REQUIRED OPTION: COMPASS SENSOR MOUNTING
(NOT INCLUDED)

  • Optional Sensor Mount MD54 or MD58 – this is not included as standard because it depends on the type of host magnetic compass. Since there are many different manufacturers of magnetic compass,  please contact MARINE DATA to obtain the correct sensor mounting

PRODUCTS FOR EXPANDING THE TMC SYSTEM
(NOT INCLUDED)

**The (optional) MD71THD Control and Display Unit is capable of displaying the heading in numeric form as a basic heading repeater (compass repeater). However, we always recommend using a dedicated MARINE DATA Heading Repeater suitable for the precise purpose to which it will be put (a repeater for steering the vessel; a repeater taking bearings; a repeater to be mounted on the bridge wing, etc. See the full range here)
