Detection beam
The detection beam of an ultrasonic sensor has the shape of
a cone. The size depends on the target and its sound
reflecting characteristics. Small and more badly reflecting
objects result in a smaller cone (narrower and shorter).
Bigger objects and those with surfaces which are not
perpendicular to the central axis can expand the cone. The
exact cone shape and size can be determined only at the
object itself. No disturbing objects must be between the
sensor and the target within the cone. Otherwise the sensor
would detect the disturbing object instead of the desired
target. On the right the typical cone shapes for the UPX
sensors are shown. The difference between bold and dotted
line represents the variation due to different targets.
Furthermore the size of the detection beam is influenced by
air temperature and humidity. The colder and dryer the air,
the larger is the beam.
No other ultrasonic sensor working at the same frequency
shall be within the cone or close to it or opposite to it. This is
only allowed when using the synchronisation option (Y-
version).
