Ultrasonic sensors for reliable detection, independent of color or transparency
Ultrasonic proximity sensor, through beam and retro-reflective sensors detect objects or fill levels independent of their color or transparency and are incredibly unaffected by soiling. They provide the greatest precision throughout the entire detection area. Different sonic cone profiles allow the sensor to be individually adjusted according to the object, environment and accessibility.

Special feature
Ultrasonic sensors are far superior to conventional sensor technology, in particular with reflecting or transparent objects, with liquids and with greater sensing distances of up to 3 m. An ultrasonic sensor can reliably solve all of these applications, as well as combinations of them. Even detection through pipes and small openings is no problem with ultrasonic sensors.

How do ultrasonic sensors work?
Ultrasonic sensors are non-contact electronic sensors. They detect objects and liquids independent of material or color using ultrasonic waves.
- Independent of color or transparency
- Resistant to dust and moisture
- Continuous resolution and repeatability across the entire measurement range
- Laminar measuring cone
- Reflection principle can be employed without the need for special reflectors
Functional principleMost ultrasonic sensors are based on the principle of measuring the propagation time of sound in the air. Packages of ultrasonic sound, so-called bursts, are emitted by the sensor, reflected by an object and received again by the sensor. The returned echo signals are evaluated by the integrated electronics of the sensor. Depending on the sensor type, either digital or analog information is then issued at the output.
Unlike photoelectric sensors, influences such as changing colors, transparency or high reflectivity have no bearing on the detection of objects. Ultrasonic sensors maintain their excellence even in harsh environments. They are extremely resistant to dirt, and process reliability is not impaired by dust, smoke, vapors, or other contaminants.
