MRU 2. the fifth generation roll and pitch motion sensor, is designed for high accuracy roll and pitch measurements in marine applications.

This unit, which must be fixed in a specific direction relative to the ship, is particularly suited for applications with a limited roll and pitch range.

It is essential for many uses such as offshore riser monitoring systems, dynamic positioning systems, telecommunication antenna systems, and motion damping systems on high-speed crafts.

Advanced Sensing Functionality

Boasting two highly precise accelerometers and MEMS angular rate gyros, MRU 2 is distinguished for its reliability that stems from solid state sensors without rotational or mechanical parts prone to wear.

MRU 2

It comes with Windows-based software for configuration and data presentation. When positioned high up in a ship, such as on the bridge, the MRU 2 outperforms inclinometers and standard Vertical Reference Units due to its capability to suppress horizontal accelerations affecting roll and pitch measurements.

Operational Design and Output

The MRU 2 outputs both static and dynamic roll and pitch angles, along with corresponding angular rate vectors.

Furthermore, it delivers surge and sway accelerations. Offering digital I/O protocols,

MRU data can be accessed via Ethernet interface and serial lines which enable the easy distribution of data to multiple users on board.
