This overview of ultrasonic sensors is to help you find the right sensor for your measurement task. The ultrasonic sensors are listed below to compare their key features.
The ultrasound is a high-frequency vibration emitted by the sensor, which is reflected by the measurement object and received again. The ultrasonic transducer calculates an analog output signal proportional to the transit time of the sound. Level measurement is a typical application for sensors base on the ultrasonic measurement principle.
