851-165183 50/200 Combi C Transducer Installation manual Warning! The transducer cable must not be exposed to oil or other petroleum fluids. See page 1 inside!
Installation manual INTRODUCTION Purpose The purpose of this installation manual is the provide the basic information required to install the 50/200 Combi C echo sounder transducer. Note that although drawings are provided to explain the installation principles, the installation shipyard must provide the final drawings required to fit each individual vessel.
Simrad 50/200 Combi C Transducer INSTALLATION This chapter provides general installation guidelines for transducer installation. The following topics are described: • Transducer location • Mounting (different methods are shown when applicable) • Cable glands • Steel conduit for transducer cable •...
Installation manual Transducer location General A single answer to the question where to locate the transducer cannot be given. It depends very much on the vessel’s construction. However, there are some important guide lines. Go deep The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves.
Simrad 50/200 Combi C Transducer Boundary water layer When the vessel forces its way through the sea, the friction between the hull and the water creates a boundary layer. The thickness of the boundary layer depends upon vessel speed and the roughness of the hull.
Installation manual Propeller noise The propulsion propeller is the dominant noise source on most fishing vessels, research vessels, merchant vessels and pleasure crafts. The noise is transmitted through the sea water. For this reason, the transducer should be placed far away from the propeller, which means on the fore part of the hull.
Simrad 50/200 Combi C Transducer Summary and general recommendation Some of the above guide lines are conflicting, and each case has to be treated individually in order to find the best compromise. Generally the propeller noise is the dominant factor, and a...
Installation manual External mounting This transducer has a streamlined housing, and it is designed for installation outside the hull. This transducer is mainly used on smaller vessels. A location approximately 0.5 m aside from the keel may be adequate for the passage of water between the keel and the transducer.

Installation manual Longitudinal angle On deplacement hulls, the transducer (A) must be mounted in an angle of 5 to 8 degrees (B) in relation to the keel (C). With a planing hull, this angle must be 0 degrees. (A) = Transducer (B) = 5 to 8°...
Simrad 50/200 Combi C Transducer Cable glands The transducer cable must pass through the hull using approved cable glands for the type of vessel in question. A steel cable gland is normally used on professional vessels with steel hulls. A bronze cable gland can be delivered as an option for vessels with wood or fibreglass construction.

Installation manual Cable gland installation for smaller vessels This cable glands made of plastic is designed for those smaller vessels that do not need to be classified. (A) = Packing nut (bronze). Ensure that you do not to damage the transducer cable by tightening the packing nut too hard! (B) = Rubber gasket...
Simrad 50/200 Combi C Transducer Cable in steel conduit It is strongly recommended to lay a steel conduit from the transducer’s cable gland to the echo sounder transceiver, and to pull the transducer cable through this conduit. There are two reasons for this.
Installation manual Handling and maintenance Do not lift the transducer by the cable. Some transducers are delivered with a cover plate on the face for protection during transport. Let this plate stay on as long as possible, but do not forget to remove it before the vessel goes into the sea.
