Ultrasonic level sensor manufacturers for distance measurement

Also, the detections are not influenced by the color, pattern, or luster of the target surface. The new generation of the ultrasonic sensors u300, u500 and ur18 impresses with reliable integrated setting and filter options via the io-link interface in every situation. Disrupting objects such as a stirring unit in the tank are ignored thanks to the unique disruption filter. Watch the video to find out more about the setting and filter options and how you can benefit from them. What is more, the unique combination of the shortest blind region on the market and extensive range offers new opportunities for machine construction and simplifies the design process.

Sensors, proximity switches and light barriers for object and position detection. Of all sensing technologies, ultrasonic level sensor may be one of the most versatile and yet one of the trickiest. A hygienic cleaning cycle reaches up to 120 ˚c, so the sensor must withstand that heat for the length of the cycle.

The device sends sound waves at a frequency higher than humans can hear, from 20 kilohertz to one gigahertz. Ultrasonic sensors work on the basic principle of sound waves to determine material level. Ultrasonic sensors are used to continuously measure semi-solid, corrosive, and viscous medias, slurries and even some solids.

Since corrosive liquids become more aggressive as temperature and pressure increase, these extreme conditions need to be considered when specifying these sensors. If you have a specialized sensing requirement, including a level switch or through wall application, we can develop a customized ultrasonic sensor solution by leveraging our large design portfolio. Ultrasonic sensors provide continuous, non-contact level measurement in bins, tanks, and silos or can detect material on conveyors. The water and wastewater industry strongly favors ultrasonic level sensors because they help with pump control, cycling and monitoring, overfill protection and more.

The signal output of each radar level transmitter delivers data to a panel meter in the control room regarding the percentage of material inside each silo as well as the overall volume of material. The transducer face of the sensor must be perpendicular to the target in order to receive the maximum sound wave energy reflecting back. Proper alignment becomes even more important as the sensing range increases. If the tank has smooth walls on the inside, our mb7052 and mb7369 sensors contain our most-likely and stability filtering. This will let the sensors choose the target that gives the largest acoustic return. The lvcn414 series is a non-contact, ultrasonic level controller and transmitter that delivers reliable performance for small-tank fluid handling control solutions.

The technique allows non-contact measurement where the heat of the molten metal makes contact techniques and even many non-contact techniques impractical. One perceived major disadvantage of microwave or radar techniques for level monitoring is the relatively high price of such sensors and complex set up. However, price has reduced significantly over the last few years, to match those of longer range ultrasonics, with simplified set up of both techniques also improving ease of use. Intrinsically safe loop-powered sensor for measuring the level or volume of liquids that exist in a hazardous rated area, or for measuring the distance to objects located in a hazardous rated area. Multi-point setting is difficult and continuous measurement is impossible.
