Ultrasonic sensors are a useful alternative when optical sensors are met with their physical limits. This applies to objects with uneven surfaces, under difficult ambient conditions, with highly transparent media, or with moving and highly reflective liquid surfaces.
Typical uses of ultrasonic sensors are checking the presence of highly transparent foils and measuring filling levels in liquid containers.
A major advantage of ultrasonic sensors is the reliable background suppression that results from their sound time-of-flight measurement principle.
Ultrasonic Sensor Highlights:
- Simple adjustment via teach-in, control input or display
- Reliable detection of objects with critical surfaces and highly transparent objects
- Available in cubic (32 x 20 x 12 mm) or barrel type (M12/M18/M30) housing options
