IEC61162 Rudder Angle Indication System

IEC61162 Rudder Angle Indication System

Product introduction

The Rudder Angle Indication System AD80 is a professional marine instrument designed to provide accurate and reliable real-time display of a ship's rudder blade position and direction. As a critical component for navigation safety, it ensures that the helmsman and engineers have immediate visual confirmation of steering commands, which is essential for precise maneuvering and collision avoidance.

Core Function & Key Specifications

The primary function of the AD80 system is to convert the mechanical movement of the rudder stock into an electrical signal, which is then transmitted and displayed on remote indicators installed in key locations such as the wheelhouse (pilothouse), bridge wings, and the steering gear room. This setup fulfills international regulatory requirements for dual-location indication.

Key specifications of the system include:

Multi-Location Display: Compliant with regulations requiring indicators in both the pilothouse and steering-gear compartment.

Dual Display Modes: Most units feature both analog (dial/bar) and digital (numerical) readouts for intuitive and precise angle reading.

System Independence: The indicator system is designed to be independent of the steering gear control and autopilot systems to ensure fail-safe operation. It draws power from the ship's emergency power source to maintain functionality during main power loss.

Robust Construction: Electrical components are housed in enclosures that meet at least IP56 protection standards, making them resistant to powerful water jets and dust ingress, suitable for harsh marine environments.

Certifications: The system is certified by major marine classification societies such as CCS (China) and DNV, confirming its compliance with international standards like IMO regulations and IEC 61162.
