As non-contact sensor, the ultrasonic sensor converts ultrasonic signals to other energy signals (usually electrical signals). It provides reliable measurement even under harsh environment, and is capable of accurately sensing smaller objects without influenced by the color, transparency, reflection characteristics and surface finish of the object; the sensing signal is output as switching signal or analog signal. The ultrasonic sensor is always used for reliably detecting and counting the objects (including the media, like powder and fluid), and accurately measuring the position and distance.
