MD71THD DISPLAY HEAD UNIT FOR TMC & EMC SYSTEMS

MD71THD DISPLAY HEAD UNIT FOR TMC & EMC SYSTEMS

The Human Input Device in a MARINE DATA Transmitting Heading Device (THD) System. Allows the magnetic correction coefficients and variation to be entered manually. Displays Heading

  • Description

    OVERVIEW

    Transmitting Heading Device (THD) Systems are becoming increasingly popular as a backup or alternative to a gyro compass. Marine Data offers both Transmitting Magnetic Compass (TMC) or Electromagnetic Compass (EMC) solutions. The TMC echoes the ship’s magnetic compass in its binnacle; the EMC directly detects the Earth’s magnetic field as a fully independent electromagnetic compass.

    The menu-driven MD71THD Control and Display Unit provides easy calibration of the magnetic heading sensor and allows the manual input of variation and deviation corrections. It provides a crystal clear digital display of heading in a compact design.

    The MD71THD Control and Display Unit from Marine Data: flexible in application, easy to install and simple to maintain.

    FEATURES

    • The Control and Display Unit supplied for a Marine Data Transmitting Heading Device (THD) System (type EMC or TMC)
    • Automatic compass sensor calibration (TMC)
    • Displays Heading with True or Magnetic Source Indication
    • High Contrast OLED Display
    • 2x NMEA 0183 outputs at the rear

    APPLICATIONS

    • Integrates all the key components in a Marine Data Transmitting Heading (THD) System
    • Calibrates the magnetic heading sensor and allows the manual input of variation and deviation corrections
