UN ultrasonic sensors used in vegetable cleaning process

10.11.2010
Ultrasonic sensors perform two tasks in one process in the agriculture industry for vegetable cleaning.

Fresh vegetables from the field must be cleaned quickly in large quantities, packaged and transported to the supermarket. At first a lot of dirt sticks on the carrots. They are cleaned in water baths and then brushed clean with mechanical rotational brushes. They are then weighed accurately and packed in plastic bags.




Compact ultrasonic sensors of the UN series from Waycon Positionsmesstechnik can be used here for two purposes. First, the level of the water bath is controlled by a sensor. Before the brushing machine two UN sensors are mounted with synchronization. They measure the level of the feed hopper and control the conveyor belt in a way that the brushing machine is always properly loaded. The environment is very rough. A lot of water, soil and carrot skin is splashing around. The UN sensors are IP67 waterproof and mechanically very robust. They work even with heavily polluted diaphragm.

The outstanding feature of the UN series is its high acoustic power combined with small sensor size. This is achieved with new optimized transducers, working at high electrical voltages. Thus also small, moving and poorly reflecting objects can be safely detected. Moreover the sensors work also under high contamination. With a length of

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
