Avoid Stressing Transducers - ohmex SONARMITE DFX dual beam Manual

When mounting the transducers the following points should be taken into consideration ...
•
How near to the Metacentre of the boat is the transducer
•
Is any turbulence generated around or in front of the transducer when moving
•
Is the turbulence from the propellers in the field of view of the transducer
The only important consideration in mounting is that the transducer is always in the water and
that the transducer does not represent an obstacle when the boat is used at higher speeds (i.e
getting to the survey location). If at all possible mounting the transducer directly below the
positioning antenna reduces the calculation of X/Y offsets to zero.

Avoid Stressing Transducers

The Active Transducers include piezoelectric elements which are embedded within a resin
compound. If the user has to fabricate a custom mounting for the transducer (a very common
requirement given the vast permutations of boats in which surveys are performed) avoid using a
fixing technique that causes physical stress in the transducer body as this will change the
resonant properties of the device and effect its depth measuring accuracy.
