Glossary
Active surface
Surface of a
proximity switch
, from which ultrasound is emitted and enters.
[IEC
60947-5-2, 2.2.11.2]
Blind zone
Zone between the
active surface
and the
minimum switching distance
, where no
object can be detected. [IEC
60947-5-2, 2.3.1.3]
Coverage range
Range, where the
switch points
can be set. [IEC
60947-5-2, 2.3.1.2]
Condition as supplied
Condition of the
USi
upon leaving Mayser. All parameters conform to the
factory
settings
.
Detection
Basic function of a
proximity switch
. In contrast to the basic function
measurement,
the objective of the evaluation of the
echo signals
is only to determine the two con-
ditions “object present” and “object not present”. (cf.
Measurement
)
Detection
fi
eld
That area within the s
onic lobe
, which is monitored by the
USi
. The detection
fi
eld
is bounded axially by the switch points and laterally and vertically by the edges of
the
sonic lobe
. (cf.
Coverage
range
,
sonic lobe
)
Diagnosis memory
Internal memory of the
Evaluation Unit
for faults, which are determined during
initialisation
.
Distance
The space between two points. First point of the
USi
is the
active surface
, second
point is the detected object. (cf.
Measurement distance
)
Echo
Returning (ultra)sonic wave.
Echo amplitude
measurement
Complex
measurement procedure
of the
USi
, where the measurement path itself is
evaluated. This
measurement procedure
provides greater safety against disruptive
signals. (cf.
Echo runtime measurement
,
measurement procedure
)
Echo envelope curve
Interim result of the
USi
internal signal processing. The echo envelope curve serves
as a basis for the
USi
internal evaluation of the
echo signals
.
Echo evaluation
USi
internal processing of the incoming
echo signals
.
Echo runtime measurement
Ultrasonic
measurement procedure
, where the time span between the transmitting
pulse and the input of the
echo signal
is used as the basis for the evaluation of the
distance
. (cf.
Echo amplitude measurement
,
measurement procedure
)
Echo signal
Signal, which generates an
echo
on the
active surface
. (cf.
Continuous echo, echo
)
Evaluation Unit
The part of the
USi
that controls the
sensor
, processes incoming signals from the
sensors
and supplying them to the
outputs
as evaluated signals.
