Ultrasonic sensor principle of operation
WebOperation Principle. Ultrasonic sensors are used for bottle detection. Ultrasonic sensors are capable of both contact-free object detection and measuring the distance of objects from the sensor. To measure, they send high-frequency sound pulses. The pulses spread out in a cone shape into the air and are reflected as soon as they hit a surface. Webgas itself, they complement sensors that measure gas concentration. This paper provides an overview of the operation and use of UGLD. The principles of ultrasonic detection and its strengths and limitations are also discussed. Reference: HSE. 2004. Fire and Explosion Strategy, Issue 1.
