The "orientation", or direction,
of the transducer is extremely important. The reason for this is simple.
-
The '+' and '-' directions are defined
by the transducer. Either '+' is towards the transducer or away from it.
-
The strobe will be triggered by a '+'
signal.
-
If you change the orientation, you change
the definition of '+'.
Are
These Bearings "In-Phase" ?

The animation
here shows both transducers oriented (pointed) in the same direction:
-
The '+' direction
is defined as 'towards' the transducer.
-
The strobe will
trigger on a '+' peak so each transducer will cause the strobe to flash
when they reach their maximum displacement to the left (towards
the transducer).
-
The strobe flashes
when the reference mark is just past 6:00.
|
-
The transducers have the same orientation
and generate the same phase angles so they are in-phase.
