Controlling variable pitch propellers (VPP's)

The critical advantage for the ship propulsion system

The solution

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.

The features

• Built in redundancy for fail-safe operation
• Standard dimensions for easy retrofitting in existing cylinders
• GL approval (Germanischer Lloyd)
