ABOUT ULTRASONIC SENSORS

Light and sound are two natural phenomena which let every living being recognize their environment without physical contact and over widely varying distances. Likewise, industrial processes require reliable environmental information. Sick's ultrasonic sensors UM 30 and UM 18 detect objects and measure distances with high accuracy.

The realm of sound is a world of its own, and for this reason ultrasonic sensors are simply the better choice in many industrial applications requiring sensor technology.

NEVER CONFUSED BY LOUD COLORS
Not even the oddest colors can bias Ultrasonic sensors. Reflecting objects do not irritate them at all. When objects change color, there is no need to readjust the sensors. They just go on working as before. Can anyone think of a more convenient way?

SOUND HAS AN ADVANTAGE - EVEN ON SUPERFICIAL INSPECTION
Whether the surface is rough or smooth, reflecting or retro-reflecting, regular or irregular in shape, ultrasonic sensors are generally unaffected. They detect objects reliably and almost independently of their appearance.

DIRECTION AND MEASUREMENT, REGARDLESS OF MATERIAL
Transparent objects such as glass and film are often a difficult task for sensors, as are clear and colored fluids. But it is hard to deceive ultrasonic sensors. Almost all materials affect and reflect sound waves.

HIGHLY RELIABLE, EVEN UNDER DIFFICULT CONDITIONS
Dust and dirt, steam and spray are no problem for ultrasonic sensors. Unfavorable environments have little effect on them. Interferences are simply "blanked out." Ultrasonic sensors do not even mind strong light and adverse temperatures.
