Glossary of terms
1oo2
(one out of two) Type of multi-channel architecture where
one area is monitored by two sensors at the same time.
Activated output (ON-state)
Output that switches from OFF to ON-state.
Angular coverage
Property of the field of view that corresponds to the
coverage on the horizontal plane.
Dangerous area
Area to be monitored because it is dangerous for people.
Deactivated output (OFF-state)
Output that switches from ON to OFF-state.
Detection distance x
Depth of the field of view configured for field x.
Detection signal x
Output signal that describes the monitoring status of the
field x.
ESPE (Electro-Sensitive Protective
Equipment)
Device or system of devices used for the safety-related
detection of people or parts of the body. ESPEs provide
personal protection at machines and plants/systems
where there is a risk of physical injury. These
devices/systems cause the machine or plant/system to
switch over to a safe status before a person is exposed to
a dangerous situation.
Field of view
Sensor area of vision characterized by a specific angular
coverage.
Fieldset
Structure of the field of view which can be composed of up
to four fields.
FMCW
Frequency Modulated Continuous Wave
Inclination
Sensor rotation around the x-axis. The sensor inclination is
the angle between the center of the field of view of the
sensor and a line parallel to the ground.
Machinery
The system for which the dangerous area is monitored.
Monitored area
Area that is monitored by the system. It is composed of all
the fields of all the sensors.
Protective field x
Portion of the field of view of the sensor. Protective field 1
is the field closer to the sensor.
OSSD
Output Signal Switching Device
RCS
Radar Cross-Section. Measure of how detectable an object
is by radar. It depends, among other factors, on the
material, dimension and position of the object.
Tolerance area
Area of the field of view where detection or not of a moving
object/person depends on the characteristics of the same
object itself.
