MRU H


 
General 
Product Name:MRU H
Product Description:The MRU H is specially designed for motion measurements in marine applications requiring highly accurate heave measurements in environments with extreme horizontal accelerations. This MRU is an ideal sensor for roll, pitch and heave compensation of offshore cranes and echo sounders. The MRU H can also be used on typical ship motion monitoring applications such as helideck motion monitoring, hydroacoustic positioning systems, as well as hull stress monitoring.

Velocity input data and formats :The MRU H accepts input of external speed and heading information on separate serial lines or Ethernet for improved accuracy in heave, roll and pitch during turns and accelerations. For time synchronization the MRU accepts 1-second time pulse (1PPS) input on a TTL line (XIN) or as RS-232/422 signal.
