MRU Compact
The NORSUB MRU Compact is a compact unit with easy installation process, supporting various communication protocols and featuring a dust and splash-proof design.
Roll and pitch dynamic accuracy of 0.05° Heave accuracy: 5 cm / 5 %
The 6000 series improves it further to 0.02°
The 9000 series achieves exceptional precision with 0.01°
Product overview
The NORSUB MRU Compact is a small, yet accurate motion reference unit that is easy to install due to its passive Power over Ethernet (PoE) interface. A regular RJ45 ethernet connector is used for both power and communication so that any cat5e cable can be connected to interface the MRU Compact. This makes installation fast and cabling costs low.
The MRU Compact is configured via ethernet (TCP) and measurements data can be acquired from UDP messages, Modbus TCP or Ethernet/IP.
The MRU Compact dust and splash proof and is suitable for mounting indoors or inside a control box.
The MRU Compact comes in three different versions: 3000, 6000 and 9000 models to accommodate for different accuracy requirements and budgets.
The MRU Compact is also available in an inclinometer version of the MRU Compact that does not include Heave/Surge/Sway outputs.
