Foam material, which is to be coated on one side, is transported on a conveyor belt. Both, the foam and the coating material can attain different colors. In order to minimize the effort, not each color is to be taught in. The differential color sensor CR200 is used to teach in a zero-difference on both sides of the foam. Independently from the color, it is possible to recognize if both sides of the foam are the same or if one side is coated. With the FOR-C2.0-50 optics this works also with deviations in positioning of approx. 20mm.

Description:
The recognition of color markings on tubes for the sorting out of faulty tubes with changing tube diameters is a task for the CROMLAVIEW® CR200 color sensor, as it can detect two measuring points simultaneously. After applying the color mark in the tube marking system, the tube moves through the system. Since the tube rotates it cannot be guaranteed that the color mark occupies a certain position. So a 360°-color-mark-detection is necessary, which can be achieved by six measuring points. When changing the diameter, all six measuring points are re-teached in parallel by a trigger pulse. Using a background target, the tube start and end can be detected.

Salmon meat actually has a white color. However, consumers do like the orange to reddish color named after him. The reason for this is the carotenoid Astaxanthin, which occurs naturally in the nutriment of salmon or in aquaculture is added to the nutriment. Price differences of up to $ 2 / kg can be achieved solely by color enhancement. For this reason, in salmon processing, the color is measured and documented with a CROMLAVIEW® color sensor. For color measurement, a suitable optics with a measuring distance of about 1 meter above the conveyor belt is attached. Due to the inclination of the optics, the gloss of the surface is largely excluded.

Laser distance sensors of the type LDM302A are used in docking systems for vessels. They measure the distance from the edge of the quay to the incoming vessel and ensure that the navigator is informed about the current distance between the vessel and the landing pier at all times. The LDM302A uses invisible, eye-safe IR laser pulses to measure the distance to almost any natural surface in up to 300m distance. For the implementation in docking systems it is crucial that all kinds of hulks, whether they are rusty or freshly painted, can be detected reliably. This is ensured by the LDM302A. The LDM302A is also able to measure the current speed of the vessel along the laser beam based on the measured distance and its change.

On the transport from the storage area to the furnace the billets are moved crossways between the two LDMs. This way the devices measure the distance to the abutting faces of the billets and send the results by PROFIBUS to a PLC, which then calculates the total length of the steel billet by using the previously known distance and the measured data. As the measurement is performed outdoors, the measuring devices have been integrated into additional protective cases. One of the two devices is to be installed directly before the entrance to the furnace. Due to the high temperatures in this area, the use of a water-cooled protective case was unavoidable.

Description:
In steel rolling mills the produced coils are stored on a large area, partly one on top of the other. When loading transport vehicles, LDS30A laser distance sensors are used, among others, to determine if the coil that is moved by the crane is in the correct position. Their high measuring rate of up to 30 kHz allows for sufficiently precise position detection while the coils are moved still hanging on the crane. Even very fast movements can be detected in a reliable way.

Description:
In the metal industry a lot of materials are processed in the form of flat straps. In the process metal straps are rolled up to coils. The coiling machines used for that need to be adjusted consistently, depending on the width and position of the strap. Distance measuring devices, such as the LDM41A are used for positioning the reels on the center of the strap. Due to their high precision and independence from the material surface properties, the coils or machine parts can be positioned accurate to the millimeter. In most cases, two laser distance measuring devices whose measured values are set against each other are deployed for this task in order to process different diameters or irregularly rolled coils. The capability to operate several devices on one bus line and to process the results in the control fast and in a central place make the LDM41P with an integrated PROFIBUS DP interface the perfect solution for positioning tasks in heavy machinery construction.

Description:
When loading and unloading sea containers on vessels and transport vehicles it is necessary to know the exact position of the container in relation to the gantry crane. In this case, the laser distance sensor LDS30A measures the distance between crane runway and container. The eye-safe infrared laser makes it suitable for the use in applications where people can be present. Despite its low power consumption the laser is able to measure on almost any solid surface, whether it is rusty, dirty or wet.

Description:
Two laser distance sensors of the type LDS30A are used on a special measuring and inspection train. They are mounted onto the roof of the train and aligned vertically upwards. It is their task to measure the distance between the train and potential obstacles above it. This is done on inspection tours of the measuring train at velocities of up to 100km/h. The extremely high sampling rate of up to 30 kHz, which the LDS30A provides, ensures that the evaluation unit receives a distance value every 3 mm on the track.

Description:
Sandwiches are conveyed on a belt, and their number is to be counted as the daily production. Due to the fact that their position is not fixed and their height is not defined either a light barrier is not suited for this task. As the conveyor belt has a defined color, this color is taught in with several CR100 color sensors which are arranged widthwise. A counting impulse is sent to a central counter in case that at least one sensor does not recognize the background. The sensors are connected with an OR-circuit in the counter.

Description:
Wire rod with a diameter of between 10 and 18mm is cut in motion with a flying saw according to customers’ specifications. The 0.1% accurate measurement of velocity performed by the VLM device ensures synchronous movement between the saw and the wire rod. Damage or early wear by measurements that are subject to slip can thus be avoided. Velocities of between 20 m/min and 60m/min are applied. Shiny, oiled or dry surfaces are detected in a reliable way.

Description:
In order to control rolling mills according to the mass flow principle or to determine skin pass level or the degree of stretching, highly accurate measurements of differential velocity at the inlets and outlets of the stands are required. The VLM devices operate optically and contact-free, without slip and with measurement accuracy better than 0.05%. Due to the fact that several devices can be synchronized, they are well-suited to the measurement of differential velocity. Appropriate protective cases allow for their use in this environment.

Description:
Ultrasonic and eddy-current testing systems for tubes and profiles require the speed of an object in order to synchronize the test probes on the moving objects. As individual objects pass the inspection line, the use of tactile measuring wheels would be very complex and failure-prone. The VLM operates optically and contact-free and records the speed of the object slip-free and precisely from the distance. At the same time the devices can determine the length of the object. The nature of the object’s surface does not have an influence on the measurement.
