Every sensing technology has its own set of unique capabilities that allow it to perform reliably in certain areas. In dirty environments, a photoelectric sensor’s light beam may fail to return to the receiver due to a covered lens or reflector. However, ultrasonic sensors thrive in dirty and dusty environments, since sound waves are unaffected by dust particles floating in the air or adhering to the sensing face. Industries that commonly use ultrasonic sensors include agriculture, food and beverage, and packaging. The following key attributes will help you select the right ultrasonic sensor for your application.
