Structural monitoring of blow out preventors (BOP) requires reliable motion sensors to measure inclination and lateral displacements.
The NORSUB Subsea MRU can be used to measure the roll & pitch angle in addition to oscillatory lateral displacements.
The small and robust titanium casing of the NORSUB Subsea MRU makes it fit for installation on the BOP.
Communication over very long cables are often needed in subsea applications. The Subsea MRU & inclinometers has 2-wire RS-485 communication with Modbus RTU. This enables serial communication for cables up to 3000 m for lower baud rates.
