elobau ​ultrasonic sensors

​Precise, versatile and ​reliable

The elobau ultrasonic range

The principle of ultrasonic technology is as simple as it is effective. High-frequency ultrasonic sound waves are emitted by the sensor, which are then reflected by the target object, and detected again by the sensor. The distance is then calculated from the elapsed time. This position can not only be used to measure distances, but also to determine the position of objects. This makes the ultrasonic sensor extremely versatile and can be used to suit the individual needs of the customer.

Fits everywhere. Three different cylindrical designs ensure effortless integration into every machine environment. In addition, the various operating modes of the sensors in combination with different analogue and digital outputs offer the right solution for nearly every possible application. Synchronisation and multiplexing serve to prevent crosstalk between the sensors, thereby guaranteeing trouble-free operation even in applications with limited installation space. Compliance with the ATEX guideline expands the already broad range of applications into the field of potentially explosive areas.

Keep it simple. Integrated LEDs help the user quickly detect the echo and switching state. The simple and fast configuration with IO-Link, teach-in button or wire saves time and costs.

elobau ultrasonic sensors are IO-Link compatible and, therefore, “Industry 4.0 ready”.

More information

IO-link makes it possible to drive digital networking and communicate from the control down to the lowest level of automation – the sensor level. IO-Link is a standardised and universal interface based on point-to-point connection that can communicate with all common fieldbuses. With simplified wiring, device diagnostics and a reduction in standstill times through simple configuration, automation can be designed even more efficiently with IO-Link. Use IO-Link and make your machines fit for the Internet of Things.

Detection of fill levels

Ultrasonic sensors are the ideal solution for reliably and precisely detecting the fill level of liquid and solid media in a container. Nearly every material can be detected with ultrasound, regardless of whether it has a glossy, matt or even transparent surface. The range of sensors available means they can be used in countless applications – with precise measurement of distances up to 8000 mm. The height of the fill level in a container can be detected through continuous measurement and output via either an analogue signal and / or via two switching signals.

Use on agricultural machinery

When cultivating farmland, ultrasonic sensors are used to conserve resources and protect machines. Mounted to the booms of sprayers, they detect unevenness in the ground and the different heights of plants that are in the growing phase. The boom can then maintain a constant distance, avoiding collisions with the ground and damage to the plants. This also ensures the optimum distribution of expensive plant protection products, allowing the operator to concentrate fully on controlling the machine.

Lateral attachment of the ultrasonic sensor to sprayer’s reservoir container allows gaps to be detected between fruit trees on fruit farms. This ensures that plant protection products are applied only to trees and not sprayed in the gaps between them. Ultrasonic sensors thereby improve the efficiency of farmland cultivation, reduce stress on the environment and lower costs for the farmers.

With their high protection classes and operating range, ultrasonic sensors are ideally suited for outdoor use and in agricultural areas.

Suitable for every application

Object detection

Counting objects

In the packaging industry, ultrasonic sensors are the perfect solution for reliably counting objects. With the use of a reference reflector, the retro-reflective mode of the ultrasonic sensor allows many types of objects to be reliably and quickly detected, whether they are sound absorbing or sound avoiding.

The reflector is ideally a plate with a smooth surface, made from a metal or plastic material. However, existing backgrounds such as walls, floors or conveyor belts can also be used as reflectors.

When counting objects, the presence of an object results in a slight deviation of the ultrasonic signal to the reference reflector. Each signal is then counted and a reliable count of the objects is reached.

​Precise for every application

Position detection

Monitoring of roll thickness

The smallest changes in the diameter of rolled materials can be detected with ultrasonic sensors. Even reflective and highly transparent media can be reliably detected. The advantages of using ultrasonic sensors over optical sensors are demonstrated here. Particularly with foils, metals and similar materials, optical sensors are pushed to their limits. Ultrasonic sensors however will effortlessly supply reliable measurement values, minimising system downtimes. Diameter detection with ultrasonic sensor is frequently used in the metalworking industry as well as in the textile, paper and plastics industries and in packaging machines.

Sag and tear monitoring

Ultrasonic sensors can not only be used to detect roll thickness, but are also ideal for monitoring the sag and identifying tears in the roll. The potential for serious damage to the material and the device is then avoided.

They were, however, developed especially for use in areas potentially subject to gas or dust explosion. Their ATEX approval makes them suitable for use in the chemical and pharmaceutical industries as well as in systems that process oil and gas.


​Ultrasonic sensor ​​2UF

​This special version of the ultrasonic sensor is specially suited for reliably detecting the fill level of mobile machines. The extreme temperature range as well as the high protection class are essential for use in these applications. With the use of an optional focus tube, precise measurement of agitated media, or while on an incline, is also possible. In addition to mobile applications, stationary applications are also possible. The fill level is output via either a voltage or current output.
