Detection zones
for different objects:
The dark grey areas are determined
with a thin round bar (10 mm dia.)
and indicate the typical operating range
of a sensor. In order to obtain the light grey
areas, a plate (100 x 100 mm) is introduced
into the beam spread from the side.
In doing so, the optimum angle between
plate and sensor is always employed.
This therefore indicates the maximum
detection zone of the sensor.
It is not possible to evaluate ultrasonic
reflections outside this area.

responding to echoes from exis-
ting measurements. To avoid this,
there has to be an unobstructed
space extending to a depth of 500
mm in front of the sensor. Only
the objects to be detected are to
be within the sensor's 20-100 mm
operating area.
Fig. 5: Unobstructed space in front of the
sensor
With the zws-7, it is vital that the
objects to be detected enter the
sound fields from the sides..
If the unobstructed 500 mm space
cannot be provided or should the
sensor be used in the «Two-way
reflective barrier» mode, then a
plane reflector at a specific distan-
ce to the sensor must be fitted.
The size of the reflector and its
working clearance from the sensor
can be taken from the table in
Fig.7.
Fig. 6: Sensor/reflector working clearance
Fig. 7: Working clearance and reflector sizes
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
The zws-7 sensor has no tempera-
ture compensation.
If the push-button is not pressed
for 2 minutes during the teach-in
setting, the settings made hitherto
are deleted.
The sensor can be reset to its fac-
tory setting.
