The DCS is designed for measuring distances between the vehicle body and surrounding surfaces in a room (garage, dock, etc.). The DCS prevents damage of the vessel body and surrounding surfaces when the vessel maneuvers in close quarters and low visibility. The DCS may be used in undocking and berthing maneuvering.
The DCS is a system of induction linear motion sensors (ILMS) in protective bodies. An ILMS determines the location of a movable part of the support beam that registers the moment of a contact with a surrounding surface and measures the distance between the vehicle body and surface after the contact.
From the ILMS, data are transferred to the Data Acquisition and Control System over the 4–20 mA analog interface.
ILMS S125 is a cost-efficient, durable, high-accuracy linear motion sensor designed for measuring linear motion in harsh underwater and maritime environments. The sensor has a rigid structure, with the body and plunger made of stainless steel 316 for superior longevity and resistance to environmental impact. ILMS S125 is waterproof and submersible (up to 3,500 m), stably operating in underwater conditions.
Using a high-frequency coil as an ILMS' sensitive unit helps significantly reduce coil threads (compared to LVDT), which improves the ratio between the stroke length and overall length and improves longevity. Accommodation of the electronic processing unit in a rigid metal body increases reliability and stability of the linear converter.
