REFLECTA/1/EC

Product catalog summary
Overview: The document outlines the technical specifications and descriptions of electro-compensation devices and compass systems used in naval applications, focusing on mine protection and navigation.
Electro-Compensation Systems: These systems are designed to minimize the magnetic field of ships, such as frigates and mine-hunting boats, using large electric coils installed in the hull. The magnetic compass deflection caused by these coils is electronically compensated by EC coils, which generate correcting magnetic fields oriented to NE (45°), NW (315°), and vertically.
T12/A/EC Reflector Reading Device: Installed in the wheelhouse roof to avoid magnetic interference, this device allows reading from the helmsman's position through a reflection tube with magnifying lenses. It is designed for navy use, meeting shock and vibration specifications, and is certified as a B-class compass for coastal navigation.
Specifications: The document lists typical coil resistance values and features such as a removable hood for direct compass reading, externally adjustable correctors, and a 360° rotatable mirror head. The device weighs 28 kg.
Product Overview: Three types of compasses with electro-compensation arrangements are available:
  • T12/A/EC: A shock and vibration-resistant speed boat compass, MED certified as a B-class compass.
  • T12/B/EC: A full-size compass binnacle for top deck mounting, suitable for coastal navigation.
  • REFLECTA/1/EC: An A-class reflector compass binnacle, globally accepted but not designed for special shock and vibration requirements.
Additional Features: Features include gas-tight reflection tubes, adjustable compensators, and illumination options.
Specifications:
  • Models include T12/B/EC and REFLECTA/1/EC, featuring gastight, nitrogen-filled reflection tubes, with shock/vibration resistant suspension options.
  • The T12/B/EC model includes a B-class T12 steering compass, suitable for coastal navigation, with a card height of 1100 mm above deck level.
  • The REFLECTA/1/EC model includes an A-class Type/11 bearing compass, suitable for worldwide use, with a card height of 1200 mm above deck level.
  • Both models have externally adjustable B+C correctors with 6 bar magnets and latitude-stable D-corrector spheres.
  • Additional features include a removable hood for direct reading, a 360° turnable mirror head, and main/emergency illumination.
Procedures and Recommendations:
  • The optical arrangement allows for reading of heading at the helmsman’s position, with the possibility of installing a horizontal by-pass if needed.
  • Flinder’s bar can be mounted for additional correction of transient magnetism.
  • The devices are designed for worldwide voyages, with the REFLECTA/1/EC model having MED type approval.
Key Data:
  • Typical resistance values for various components are provided, with a tolerance of +/- 20%.
  • The weight of the T12/B/EC model is 95 kg, while the REFLECTA/1/EC model weighs 120 kg.

REFLECTA/1/EC-1

Electro-compensation Devices Elektro-Kompensations Einrichtungen Degaussing Device? EC-coils? Degaussing arrangements (for mine protection on fregates, corvets and mine hunting boats) are to reduce the ship´s own magnetic field. For this different large electric coils are installed in the ship´s hull. The deflection of the magnetic compass caused by these coils must be electronically compensated by coordinated coils near the compass. These so-called EC (Electro compensation) coils generate correcting magnetic fields to NE (45°), NW (315°) and vertical direction corresponding to ship´s ahead. According to the actual applied degaussing coil configuration the relevant EC coil configuration can be activated. MES-System? EK-Spulen? MES-Anlagen (Mineneigenschutz auf Fregatten, Korvetten oder Minen-Jagdbooten) reduzieren das magnetische Eigenfeld des Schiffes. Dazu werden im Rumpf elektrische Spulen angeordnet. Deren ablenkende Wirkung auf den Magnetkompass muss durch korrespondierende Korrekturspulen in Kompassnähe elektronisch kompensiert werden. Diese sog. EK(ElektroKompensations) -Spulen erzeugen Magnetfelder in NO (45°), NW (315°) und Hochrichtung bezogen auf die SchiffsVorausrichtung. Je nach verwendeter MES Spulen-Konfiguration kann eine entsprechnde EK Spulen -Konfiguration aktiviert werden. Product Overview There are three types of compasses for the different applications with electro-compensation arrangement available: •Reflector reading device T12/A/EC with T12 compass. T12 is a special shock & vibration resistant speed boat compass but as a spherical compass it is only MED certified as a B-class compass for coastal navigation. •Reflector Compass binnacle T12/B/EC with T12 speedboat compass. It is a full size compass binnacle to be mounted on the top deck of the vessel to grant less magnetic interferences.It is only coastal certified because of the T12 compass but can be used worldwide from technical point of view if Navies waive civil regulations. •Reflector compass binnacle REFLECTA/1/EC. REFLECTA/1 is a worldwide accepted A-class reflector compass binnacle by MED. The used Type/11 compass is not designed to fullfill special shock & vibrations reqquirements. Produkt Überblick Es gibt drei Kompasstypen für die unterschiedlichen Einsatzgebiete mit Elektro-Kompensations Einrichtung: •Reflexions-Aufsatz T12/A/EC mit T12 Kompass. T12 ist ein speziell schock- & vibrationsfester Schnellboot-Kompass, aber als Kugelkompass ist er nur als B-Klasse Kompass vom MED für Küstennavigation zugelassen. •Reflexions-Kompassanlage T12/B/EC mit T12 Schnellboot Kompass. Es ist ein vollwertiger Kompass Stand, der auf dem Peildeck montiert wird, um ausreichend magnetischen Schutzabstand zu gewährleisten. Gemäß Zulassung ist er wegen des verwendeten T12 Kompasses nur für Küstenfahrt einsetzbar, es sei denn die Marinen verzichten auf Erfüllung der zivilen Normen. •Reflexions-Kompassanlage REFLECTA/1/EC. REFLECTA/1 ist für weltweite Fahrt als A-Klasse Kompass MED zugelassen, allerdings erfüllt der eingesetzte Type/11 Kompass keine speziellen Schock & Vibrations Anforderungen. EC-Design Electro-compensation coils are usually orientated to NE, NW (45°, 315° to ship´s ahead) and vertical. These intermediate directions are different to conventional magnet copensation, that are in ship´s logitudinal, cross and vertical direction. Per each direction are 4 groups of coils. Each group consists of 2 coils bracketing the compass. Three of these groups have coils with same number of windings, one is with double windings. The cables of each group will be lead out separatly and can be connected to the driving circuit individually according to the requirement of the different Degaussing coils. Alterations and Errors reserved / Änderungen und Fehler vorbehalten EK-Design Elektro-Kompensations Spulen sind üblich in NE, NW (45°, 315° zu Schiffs-Voraus) und vertikal orientiert. Diese Interkardinal-Anordnung unterscheidet sich von der konventionellen Magnet Kompensierung in längsschiffs, quer- und vertikal Richtung. In jeder Richtung gibt es vier Gruppen von Spulen. Jede Gruppe besteht aus zwei Spulen, die den Kompass gegenüberliegend einfassen. Drei dieser Spulengruppen haben gleiche Windungszahl, eine die doppelte. Die Anschlusskabel jeder Gruppe werden separat herausgeführt und mit dem Treiber-Schaltkreis individuell verschaltet je nach aktivierter MES Spulen-Konfiguration. 14/Co/267B/1

Electro-compensation Devices Elektro-Kompensations Einrichtungen T12/B/EC is a full-size reflector compass binnacle with built-in T12 speedboat steering compass Compared withT12/A/EC the card height above deck level is 1100 mm. Because of this the distance to interfering magnetic sources can be extended further. The optical arrangement comprising individually adjusted lenses allows reading of heading at the helmsman´s position. It is possible to install an horizontal by-pass if the steering position is not right below the compass. The correctors B+C and heeling are inside the binnacle. D-spheres...

Compared with T12 compass is it an A-class compass for worldwide use (refer to REFLECTA/1 brochure) but the compass Type/11 is not especially designed to withstand shock & vibration as speedboatcompass T12. The card height above deck level is as standard 1200 mm. A Flinder´s bar can be fitted. The reflection optics arrangement comprising individually adjusted lenses allows reading of heading at the helmsman´s position. It is possible...
