A System
To purchase a complete system, one transmitter and one of the four receivers are ordered as separate items.
Please review the SONARANGE Accesories PDF for factory made cables.

Application hint
By means of a hole (a shaped orifice) in front of the receiver (to be machined by the customer), the ultrasound beam can be focused. Thus even smaller objects can easily be detected. This is possible also in dirty environment where optical sensors will fail after short time.

Properties
Ultrasonic sensors are perfectly suited for detection of objects with very different surfaces and under bad environmental conditions (dust, dirt, fog, bright light). A disadvantage is their relatively low measuring speed, caused by the slow speed of sound compared e.g. to the speed of light. Moreover the so called blind range of ultrasonic scanner type sensors (transmitter and receiver in the same sensor) might be sometimes a disadvantage, too.

Those disadvantages are eliminated with the ultrasonic barrier UPB. In the same way as with a light barrier, the full range between transmitter and receiver can be used. There is no blind range. The measuring speed of 200Hz is very high as well. The microprocessor controlled UPB series combines high acoustic power with small size. This is achieved with new optimized acoustic SONARANGE transducers working at high electrical voltages.

The high measuring speed combined with the large measuring range of 1500mm are the outstanding characteristics of the UPB ultrasonic barrier.
