2,Introduction
The highly advanced Ultrasonic sensor makes use of sound waves to
carry out non-contact and completely wear-free detection on various
target subjects. It possesses the remarkable capability to be
employed for the detection of either transparent or richly colored
objects, whether they are metal objects or non-metallic ones, as
well as substances in the forms of solid, liquid, or powdered
matter. The ambient conditions, such as the presence of
environmental smoke, fine dust particles, diverse environmental
factors, or even rainfall, have an extremely negligible impact on
the outstanding detection performance of these ultrasonic sensors.
For instance, in the intricate assembly lines of a modern
automotive factory, the Ultrasonic sensor accurately detects both
transparent plastic components and metallic parts without any
physical contact or wear, ensuring seamless production. Even in a
dusty and smoke-filled construction site or during a rainy outdoor
industrial inspection, the sensor maintains its superior detection
accuracy and reliability, unaffected by the challenging surrounding
conditions. This makes it an indispensable tool in a wide range of
industries where precise and reliable object detection is crucial,
regardless of the nature of the objects and the complexity of the
environment.
3,Principle
Transmitting ultrasonic transducer emits ultrasonic pulses
propagated to the measured media through communication media,
through reflection and then return to the receiving transducer
through the acoustic medium, the measured ultrasonic pulse
propagates from the transmitter to the receiver in the acoustic
medium of time. Then according to the speed of sound in the
acoustic medium, it can be considered from the transducer to the
media surface distance. To determine the liquid level. Therefore,
we can calculate the distance from the probe to the reflecting
surface D = C * t / 2 (divided by 2 is because the sound waves from
the transmitter to the receiver is actually a round, D is the
distance, C is the speed of sound, t is the time).
