Glossary
Switch point
Determined
switching distance
. Two switch point are always determined at the
USi:
switch point SP1
and
switch point SP2
.
Switch point SP1
The sensor-proximal
switch point
of the USi. The following applies: SP1 < SP2.
Switch point SP1 is preset to 1 [cm] in
delivery condition
.
Switch point SP2
The sensor-distant
switch point
of the USi. The following applies: SP2 > SP1.
Switch point SP2 is preset to 200 [cm] in
delivery condition
.
Teach In
Function, which causes the
USi
to teach in the currently prevailing environment in
the
detection
fi
eld
and to consider all
secondary objects
as given. Also available as
a button in the
Diagnosis
mode of the
parameter assignment software
(optional).
Temperature compensation
Internal function of
ultrasonic proximity switches
, which balance the typical ultra-
sonic
temperature drift
. (cf.
Temperature drift
)
Temperature drift
Deviating measurement behaviour of
ultrasonic proximity switches
dependent on
temperature. The typical ultrasonic temperature drift is generally balanced by inter-
nal
temperature compensation
. (cf.
Temperature compensation
)
Transducer
Abbreviated name for
ultrasonic transducer
. Referred to as
sensor
for USi.
(cf.
Sensor
,
Ultrasonic transducer
)
Transmission burst
Start sequence of an ultrasound bundle which is transmitted. May be heard as a
crackle.
Transverse re
fl
ections
Unwanted echos generated by unfavourable environmental conditions. Transverse
re
fl
ection can lead to malfunction of the
ultrasonic proximity switch
.
Ultrasonic frequency
Sound frequency, with which an
ultrasonic proximity switch
operates.
Ultrasonic proximity switch
Proximity switch, which transmits ultrasonic waves in an active zone and receives
a semiconductor switching element. [IEC
60947-5-2, 2.1.1.3] (cf.
Proximity switch
)
Ultrasonic transducer
Part of an
ultrasonic proximity switch
, which can transmit the ultrasonic waves via
the
active surface
and receive resulting echos. Referred to as
sensor
for USi. (cf.
Sensor
,
Transducer
)
USi
Abbreviation for Ultrasonic Industrial Sensor.
USi-IP
Abbreviation for USi with one power output and three PNP outputs.
USi-PP
Abbreviation for
USi
with two PNP outputs per sensor.
USi-UP
Abbreviation for USi with one voltage output and three PNP outputs.
