Ultrasonic proximity sensor, also known as ultrasonic level sensor, ultrasonic distance sensor, can detect any object within 2.5cm to 10m. Ultrasonic proximity switches are used to detect objects of different materials, shapes, colors or concentrations with excellent accuracy, flexibility and reliability. Its application range is very wide. Whether it is liquid level measurement or height measurement, whether it is distance measurement or bottle counting, whether it is 2.5cm or 10m, objects with different characteristics can be detected. And can be solid, liquid, powder, or even transparent objects. Detection is independent of the nature of the surface, which can be rough or smooth, clean or dirty, wet or dry. Proximity switch sensors are very robust and insensitive to dirt, ambient light or noise.
Ultrasonic proximity sensor working Principle
Ultrasonic proximity switch sensor work only with air medium and can detect any object that can reflect ultrasonic waves. The sensor cyclically emits ultrasonic pulses. After these pulses are reflected by the object, the resulting reflected waves are received and converted into an electrical signal. The detection of incoming echoes is based on their intensity, which in turn depends on the distance between the object and the ultrasonic proximity switch. Ultrasonic proximity switches work on the principle of reflected wave propagation, i.e. evaluating the time difference between the transmitted pulse and the reflected wave pulse.
What are the advantages of ultrasonic liquid level distance sensors?
First measure accurate to the millimeter, independent of color and material, even transparent objects can be detected, can be individually parameterized, small, compact housing, insensitive to temperature, noise, light or water, sensor with IQ-Sense , support worldwide use: UL/CSA certification, suitable for Ex Zone 2/22, etc.
What are the application areas of ultrasonic sensors?
Ultrasonic sensors are widely used in fill level and height sensing, gap measurement, coil diameter sensing, bottle counting, dimension measurement, material accumulation height measurement, diameter and velocity measurement, contour measurement, loop monitoring, quality inspection, distance monitoring, filling Liquid level measurement
Dimensional measurement, material accumulation height measurement, diameter and velocity measurement, contour measurement, loop monitoring quality inspection, distance monitoring Material, liquid level measurement, etc.
Ultrasonic distance sensors can be widely used in level (liquid level) monitoring, robot collision avoidance, various ultrasonic proximity switches, and anti-theft alarms and other related fields. It is convenient to connect with industrial display instruments, and also provides probes with larger launch angles.
ultrasonic distance level switch sensors can apply for agreessive chemicals or food?
Yes, absolutely, For use in food or aggressive chemicals, upon request, the ultrasonic sensor can also be protected with a Teflon film and equipped with a stainless steel housing. Ultrasonic proximity switches using ultrasonic technology can detect various types of objects, including various liquids, powders or granules, as well as colored and transparent objects. Whether the surface of the object is rough or smooth, clean or dirty, wet or dry, it does not matter to the SUL802 ultrasonic sensor. Even at the maximum working distance, all levels or smooth surfaces can be detected reliably with an angular deviation of up to approx. 3° from the sound cone. Depending on the peak-to-valley height of the object, the angular deviation may be higher. In general, objects can enter the sound cone from all directions.
