Sensor position

6.1

Basic concepts

6.1.1

Determining factors

The sensor installation height and inclination should be decided together with the angular coverage and the
detection distances in order to have optimal coverage of the dangerous area.
6.1.2

Sensor installation height

The installation height (h) is the distance between the center of the sensor and the ground or reference
plane of the sensor.
6.1.3

Sensor inclination

Sensor inclination is the rotation of the sensor around its x-axis. Inclination is defined as the angle between
a line perpendicular to the sensor and a line parallel to the ground. Three examples are presented as
follows:
sensor tilted upwards: α positive
l
straight sensor: α = 0
l
sensor tilted downwards: α negative
l

Sensor field of view

6.2.1

Types of field of view

During the configuration phase, for each sensor it is possible to select the angular coverage (see Angular
coverage on page 37).
The actual detection field of the sensor also depends on the sensor installation height and inclination. See
Calculation of range of distances on page 55.
6.2.2

Areas and dimensions of the field of view

The sensor field of view is composed of two areas:
detection field [A]: where detection of objects similar to humans in any position is guaranteed.
l
tolerance area [B]: where the actual detection of a moving object/person depends on the characteristics
l
of the object itself (see Factors that influence the reflected signal on page 36).
