EM 122
Transducer modules
To make the installation of the transducers easier, they are built with standard modules
• All RX modules are identical.
• All TX modules are identical.
Each module has its unique serial number.
The two transducer module types are identified by their unique registration numbers,
which are moulded into the rear of the element.
The transducer modules are assembled in the mounting frames especially designed for
this purpose. The modules are secured with steel brackets, while the cables are pulled
out on the side of each array.
