Ultrasonic Sensors Through sonar-reflected sound, Siemens BERO ultrasonic sensors can detect any material in virtually any environment. And not just any solid material. These advanced sensors can also trigger in response to liquids and powders. Their exceptionally broad application range includes clear object detection, level sensing, and object counting. Extraordinary capability under virtually any condition Need a sensor that can detect objects at distances as close as 6 cm (less than 2-1/2 inches) - or small objects as far away as 10 m (more than 32 feet)? Or a sensor that isn't affected by low visibility conditions such as dust or paint mist? Choose Siemens BERO ultrasonic sensors. Despite their tolerance for harsh environments, they're remarkably accurate. These sonar-technology sensors detect virtually any material, including liquids and powders. They respond regardless of surface character or condition - wet or dry, clean or soiled, rough or smooth. Their operation is not sensitive to reflections, glare, or other light conditions. Nor are they adversely affected by object color, vibration, or noise interference. Supporting a wide range of applications Here's remarkable flexibility. The most common ultrasonic sensor uses are level sensing, web break, transparent object detection, and height or distance measurements. You'll see them at work in industries as varied as conveying, automobile manufacturing, and sewage treatment.
