The HTU 420B ultrasonic sensors in red housings with their IO-Link interface and two switching outputs are suitable for demanding detection tasks. The adjustable sound cone enables extremely flexible use of the sensors and minimizes the number of different variants required in the system: One sensor type can be used for different applications. With a narrow sound cone, it is possible to detect fill levels through small openings, for example. A wide sound cone is suitable for e.g. reliably detecting diffusely reflective objects such as products with an uneven or complex surface or structure. An interruption filter detects brief changes in measurement within a certain interval caused by interfering objects (e.g. agitators) and can suppress interfering signals. Two independent switching outputs enable two positions to be monitored or two fill levels to be detected.
