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.
