SONARANGE ULTRASONIC SENSORS
2<br />
UPK series<br />
The outstanding feature of the UPK series is its high acoustic power combined with small sensor<br />
®<br />
size. This is achieved with new optimized SONARANGE -transducers, working at high electrical<br />
voltages. Thus also small, moving and poorly reflecting objects can be safely detected. Moreover<br />
the sensors work also under high contamination.<br />
With a length of < 40 mm the UPK sensors are the most compact ultrasonic sensors for that wide<br />
measuring ranges.<br />

UPR-A series<br />
Outstanding features of the UPR series are the compact M18 size and the<br />
®<br />
version with 90° angled SONARANGE -transducer for confine mounting<br />
conditions.<br />
The sensors are available as pure proximity switches and as distance sensors<br />
with V or mA analogue output as well. Typical applications are detection of<br />
objects and distance and level measurement.<br />

UPR-A CP series<br />
5<br />
<strong>Ultrasonic</strong> distance and proximity sensors<br />
Oil resistant<br />
resistant against chemicals (PVDF/PTFE housings) ®<br />
The UPR-A CP series sensors are specially designed for use in a chemically<br />
harsh environment. The high resistance is based on PVDF or PTFE material.<br />
A typical application is the level measurement of acids and alkalis in<br />
smaller containers. This sensor is based on UPR-A 1500.<br />
The front part exposed to the medium is made of PVDF, upon request also<br />
of PTFE. Both materials are extremely robust and resistant. The outstanding<br />
feature is the ultrasonic transducer which is PTFE foil covered but transparent<br />
for ultrasonic waves. The rear part of the sensor with connector is<br />
not resistant against chemicals.<br />
For OEM applications the shape of the housing can be ordered customized.<br />
Thanks to the new transducer sealing made of Viton the UPR-A sensors are<br />
very robust against many environmental influences. In particular they are oil<br />
resistant, unlike many other ultrasonic sensors.<br />

UPX series<br />
The UPX sensors are fast ultrasonic proximity switches. Thanks to the new<br />
®<br />
transducer sealing made of Viton the UPX sensors are very robust against<br />
many environmental influences. In particular, they are oil resistant, unlike<br />
many other ultrasonic sensors.<br />
The main difference between the two UPX models is their different shape of<br />
detection beam.<br />

UPS series<br />
7<br />
The ultrasonic sensors of the UPS series are particularly small and they<br />
have a narrow detection beam. Thus they are well suited to detect objects<br />
in the near range up to 200 mm and under confined conditions.<br />
The UPS sensors are available as well as pure proximity switches as also as<br />
distance sensors with analogue mA or V output. The switching or measuring<br />
distances can be learned by a teach-in procedure.<br />
UPS series FB (Focus BEAM)<br />
Miniature sensor with focusing device for smallest containers<br />
The ultrasonic sensors of the UPS 150 FB series are equipped with a<br />
focusing device made of glass fiber reinforced polypropylene which makes<br />
the sound beam particularly narrow.<br />
Therefore they are suitable in the near range up to 150 mm to sence<br />
through narrow openings. A typical application is measuring of liquid level<br />
in small tubes or containers.<br />

UPS Series CP<br />
Miniature sensor with chemically resistant head<br />
The diaphragm of the series UPS 150 CP is coated with a thin PTFE foil.<br />
The head made of chemically resistant PVDF serves as mechanical fixation for<br />
the foil and protection of the sensor front part.<br />
Thus the front part of the ultrasonic sensor becomes resistant to most<br />
chemicals.<br />

®<br />
SONARANGE THROUGH BEAM<br />
<strong>Ultrasonic</strong> sensors are perfectly suited for detection of objects with very different<br />
surfaces and under difficult environmental conditions such as dust, dirt, fog or<br />
bright light.<br />
A disadvantage is their relatively low measuring speed, caused by the slow speed<br />
of sound compared e.g. to the speed of light. Moreover the so-called blind range<br />
of ultrasonic scanner type sensors – transmitter and receiver in the same sensor –<br />
might be sometimes a disadvantage, too.<br />
Those disadvantages are eliminated with the ultrasonic barrier UPB. In the same<br />
way as with a light barrier, the full range between transmitter and receiver can be<br />
used. There is no blind range. The measuring speed of 200 Hz is very high as well.<br />
The high measuring speed combined with the large measuring range of 1500 mm<br />
are the outstanding characteristics of the UPB ultrasonic through beam sensors.<br />

parts<br />
Application hint<br />
Features<br />
Testing punch holes in packaging<br />
By means of a hole orifice in front of the receiver the ultrasound beam can be focused. By that<br />
even smaller objects can easily be detected. This is possible also in dirty environment where<br />
optical sensors will fail after short time.<br />

Why ultrasound<br />

Sonic field of SONARANGE ultrasonic sensors: measurably higher sound power!<br />
General<br />
<strong>Ultrasonic</strong> sensors are mainly used in machine manufacturing and process<br />
control for distance measurement, as proximity switch and for room<br />
supervision.<br />
They work after the principle of time of flight measurement of sound. The<br />
time of flight in air – back and forth – is approx. 6 ms per meter.<br />
The innovative ultrasonic edge sensors however are working based on<br />
analysis of sound intensity.<br />
Ultrasound is very robust compared to other measuring principles. It passes<br />
dirty environment as well. Furthermore it is reflected by almost all surfaces.<br />
Thus it makes independent of material, color and surface structure of the<br />
target to be detected.<br />
Limits of ultrasonic sensors<br />
Relatively slow, switching speed approx. 1...25 Hz<br />
Exception: <strong>Ultrasonic</strong> through beam > 200 Hz<br />
Resolution approx. 0.5...2 mm, due to wave length of sound<br />
Works only in air<br />
Problems in case of very hot or very cold targets<br />
