Five common applications of ultrasonic sensor

By using high-frequency sound waves to detect the position and distance of objects, ultrasonic sensors can usually work in the absence of other types of sensors. They work like echolocation in bats or dolphins. These Industrial ultrasonic level sensor emits sound waves (inaudible to humans) and then detect when sound waves bounce back after hitting an object. By using sound, ultrasonic sensors can detect objects that frustrate other types of sensors, and can work in some very clever situations.

The following are five examples of ultrasonic sensor applications.

Assist ultrasonic target detection in the driving. Many major car manufacturers and technology companies are testing fully autonomous self-driving cars. Nissan and General Motors even stated that they will test-run autonomous vehicles on the roads by 2020. Both types of autonomous vehicles (and human-driven vehicles that incorporate driver assistance technology) make extensive use of ultrasonic sensors to monitor roads and surrounding areas. For example, an ultrasonic sensor can detect cars in adjacent lanes for "blind spot detection" and alert the driver when someone is in a blind spot.

For ultrasonic distance detection ,Similarly, ultrasonic sensors can also prevent collisions by detecting when cars or other objects in front of and behind the car are dangerously close. For example, when is parking, the ultrsonic sensor can monitor the distance between the car and the wall or other vehicles, and remind you to park. The same applies to traffic conditions, because even if both objects are in motion, these ultrasonic sensors can work normally.

Ultrasonic sensors are entering the factory away from the road can help keep the automated production line running smoothly. With printing facilities, such as those that print newspaper or magazine pages, the paper usually starts with a roll, and as the paper is used, the diameter of the roll will decrease. Using ultrasonic liquid level sensor, the device can automatically detect when the roll is used up, so they can prepare to replace it with a new roll without losing productivity. Ultrasonic sensors can even be used with sound-absorbing materials such as rubber or fillers.

Ultrasonic depression detection. Ultrasonic sensors can also ensure that any conveyor belts, wires or cables that may be used in manufacturing or other industrial environments are placed where they should be. Cable sag will slow down or stop the production line, these ultrasonic sensors can automatically detect whether these objects are running evenly, and even need to be tightened. Ultrasonic sensors can exert incredible accuracy, which means they can even detect small defects or malfunctions. Even better, particles such as dust that may be generated during the manufacturing process will not affect its sensing capabilities.

About ultrasonic liquid level detection,this is another example of process automation in the food production industry. The high range ultrasonic sensor adopts hygienic design and is completely encapsulated in stainless steel, which can maintain good performance even when processing food. For example, it can help dairy plants produce cheese continuously rather than in batches by monitoring the levels of milk and rennet in the coagulator. In this way, it knows when to provide more of these ingredients when the cheese curd is continuously removed at the other end.
