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 worse 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. Shown above is a typical cone shape for the UPR-B
sensors. 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.
Mounting
Ultrasonic sensors shall be mounted as soft as possible in
order keep acoustic disturbances away from the mounting
spot. Thus two M18 nuts, washers and rubber sleeves for
mounting are included. The rubber sleeves for a hole of
Ø21mm shall be used at all events.
