Sensors that defy the elements
The demands placed on the technology involved in offshore and ship technology are enormous. Among other things, heavy loads must be moved, propellers adjusted, stabilizers controlled and the course maintained. And all this in an occasionally harsh climate at sea. Hydraulics are superior to other solutions when it comes to these challenges. But to be superior, they need the right sensors. Reliable and robust technology from Balluff withstands strong winds, high seas and aggressive salt water.
Heavy seas present a problem for many passengers, especially when it comes to cruises. Stabilizers minimize ship movements. Depending on the position, the optimal fin angle is changed to keep the ship as vertical as possible in the water. Our BTL HB magnetostrictive linear position sensors reliably guarantee the correct adjustment of the angle.
Balluff position measurement technology makes it possible to continuously adjust the rudder so that a ship is kept on course. Balluff Micropulse linear position sensors continuously monitor the position of the rudder, and allow reliable dynamic control.
Water-jet propulsion systems are used for high speeds at heavy seas or for maneuverability when traveling slowly. The hydraulic cylinders that control the infeed must be able to respond quickly and reliably to control inputs. Balluff Micropulse linear position sensors, which are fully integrated into the cylinders, reliably measure these movements, and provide the position feedback required for precise operation.
Variable pitch propellers (VPP's) bring critical advantages to the ship propulsion system. VPP's are particularly advantageous for use on vessels whose speed is frequently varied, such as ferries and cruise ships. Hydraulic cylinders are often used to change the prop pitch. Balluff triple-redundant Micropulse linear position sensors provide the precise cylinder position feedback required for precise and dynamic control.
Cranes are used at sea for heavy loads. For reliable operation, hydraulics and sensors attuned to the harsh seas are necessary. Our explosion-proof inductive sensors reliably detect the end position of the offshore crane. In doing so, they make work safer.
Intelligent hydraulics with our triple-redundant Micropulse magnetostrictive linear position sensor compensates for all boat swaying. Even in heavy seas, people from the supply vessel can safely reach the platform or the offshore wind power plant.
