Position Detection using Ultrasound

Precisely, for every application

Position detection of objects plays an important role in numerous industries, such as the monitoring of roll winders. It provides safety up to a certain degree with distance measurement; if for example, a too-low distance is detected between objects that could result in a danger to life and limb.

    Example of Use: Monitoring Roll Thicknesses

    For rolled materials such as paper or foils, ultrasonic sensors detect even the smallest of changes of the roll diameter and safely and reliably detect even transparent or reflective media. Even in this area, the technology shows its superiority when compared with optical sensors. That’s because with metals, foils and materials with other similar properties, optical testing systems soon reach their limits.

    The precise acquisition of measured values contributes significantly to reducing system downtimes. That’s why more and more companies who process metals, plastics, paper or textiles are turning to ultrasonic technology, instead of dealing with the flaws of optical systems.

    Example of Use: Slack and Tear Checks

    It’s not only when examining roll diameters that the superiority of ultrasonic sensors becomes clear. They provide outstanding results even when monitoring slack or detecting cracks in foils or paper strips and can thereby prevent damage to other materials and machines.

    Example of Use: Construction Site Safety

    As mentioned above, position detection and distance measurement by means of ultrasonic sensors are superior in hazardous areas. For example, consider working with lifting platforms at construction sites. These devices make it easier to work at height and often replace the laborious, time-consuming task of constructing scaffolding. This significantly increases productivity on construction sites.

    On the other hand, something that should not be overlooked within the safety aspect is that here the human is practically a part of the machine with which they are working. A small accident and this can lead to serious accidents which could affect people on the lift or below. Ultrasonic sensors, when installed in the right places, contribute to making sure working with lifting platforms is safe; whether that is under the platform, around the lifting arm, or in the immediate vicinity of the device.

    In this way, collisions with building walls, trees or people can be reliably avoided. Sensors are programmed in such a way that if there is a risk of collision, the platform first of all switches to a slow speed, and if the danger is imminent, to a complete stop.

    To ensure a short response time and inhibit a mutual fault, during installation, reliable synchronisation of the sensors must be ensured.

    APPLICATION

    elobau Ultrasonic Sensors

    Precise, flexible, reliable

    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.

    elobau Ultraschallsensor U18s

    Ultrasonic Sensor U*18

    distance measurementobject detection

    ​Thanks to the compact and robust design, the U*18S is the optimum solution for difficult application conditions. In combination with various output forms, the space-saving version offers flexibility for measuring and switching applications. In addition, this series can be used either as a diffuse reflection sensor or as a retro-reflective sensor.

    Ultrasonic Sensor U*18S

    distance measurement

    Ultrasonic sensors of the U*18 series offer maximum functionality and precision, even under demanding conditions, including in potentially explosive environments. Two different housing materials, an operating range of up to 2.2 metres, four operating modes and various output forms leave no application unsolved. Simple configuration, either via teach-in button or IO-Link, also ensures high system availability. Synchronisation as well as multiplex mode ensures high process reliability even when operating multiple sensors simultaneously.

    Ultrasonic Sensor U*30

    level measurementdistance measurementobject detectionposition detection

    Thanks to high-performance electronics, the U*30 series is the ideal partner for wide-range detection of objects and filling heights of distances of up to 8 metres. Like all cylindrical designs from elobau, the sensors are temperature compensated to achieve high accuracy even in the case of temperature fluctuations. Available in stainless steel and plastic versions, the versatility of this sensor allows it to be used for a wide range of application requirements.

    Ultrasonic Sensor UDA18 ATEX

    ​UDA18 ATEX ultrasonic sensors have the same functions and features as the sensors of the U*18 series. 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.
