True physical detection pattern of the MWS7:
Note: This is the optimal detection pattern of the microwave electronics within the MWS7 that gives the
best sensitivity. It is however possible for objects to be detected outside these angles shown, especially if
the object is large and metallic. The fully adjustable range cut-off area shown in subsequent diagrams still
applies however, regardless of the type and size of object.
Several scenarios are given below. Please contact our technical department for further information.
Example 1
Height: 3m
Range limit: 20m
Sensor angle: 12°
This scenario gives the best
definition of the range cut-off and
full area coverage, but is often not
achievable in real-life situations due
to the low mounting position.
Example 2
Height: 7m
Range limit: 25m
Sensor angle: 28°
Note that there is a detection ‗dead
area‘ under the sensor where
detection of, for example, a person
is far less likely. The range cut-off
now varies with height, due to the
cut-off being a radial distance from
the sensor.
