One method of measuring thickness is to calculate values from two opposing distance sensors. With up to six inputs, the CSP2008 universal controller allows synchronous recording of measured values from optical sensors: A pair of sensors is connected directly to the controller, another pair is connected via the EtherCAT fieldbus coupler and an integrated extension terminal. Two analog sensors measure the width of the material. These sensors are connected via a dual-channel analog input terminal. After the sensors have recorded their values, the CSP2008 calculates material thickness and width. Three switching inputs are used to set masters as per a calibration standard.

Heat exchangers in plant and machinery serve as heat transfer mechanisms between different material flows. To maximise the heat-emitting area, they are designed using multiple plates. Respectively one connecting flange for the material-conveying cables is welded or soldered onto the last plate. The position and the flatness of the flanges have to fulfill highest requirements so that these can be connected at the desired point.

Coordinate measurement machines are usually used for measuring many different components. 

Different scanners and measuring equipment measure the surface of the component in three dimensions by touching the surface of parts.

Laser line scanners from the scanCONTROL 2800 and 2700 series are ideally suited for this purpose. 

They measure the actual surface of the component without contact and with micrometer precision according to the triangulation principle.

Mabotic develops and manufactures various designs of digital scanning units. scanCONTROL laser scanner are often used for digitization of parts. The scanner projects a laser line onto the object being measured and records the profile of the line. When the scanner is mounted on a linear axis and the scanner traverses over the measurement target, a 3D image of the target can be generated.

With sectional doors for parquet or laminate flooring, key and slot joints for individual sections are applied. However, these sections are opened and closed frequently. To enable a robust but permanent flexible key and slot joint, specified  dimensions  are  critical  and  must  be  adhered to. This is particularly important in the case of significant temperature differences or inaccurate dimensions, where the door could be locked or positioned incorrectly. The measurement of the key and slot joint is therefore critical in ensuring the correct manufacturing dimensions.

A German manufacturer of prestressed concrete products uses a number of 3D measurement systems by InSystems Automation with optical sensors made by Micro-Epsilon for quality control of railway sleepers. The systems include a portal station that is fitted to a forming station above the conveyor technology. Two scanCONTROL LLT2800-100 laser profile sensors travel along the portal axes and scan the sleepers from above.

Measuring complex part geometries is a task for the scanCONTROL laser scanner. Laser scanners are used in the precision machines of EHR in order to perform a component inspection at high resolution and without contact. The special feature is that using a scanner, not only is an inspection possible from the outside but also from the inside.

The company „Paul von der Bank“ in Hilden (Germany) develops and manufactures modular-designed robotic welding cells and fully automatic production and processing lines. To ensure high production quality of longitudinally welded pipes, the following factors must be considered: Besides sheet edge length, the exact edge position must be known, it must be guaranteed that sheet edges are aligned perfectly to each other.

For automatic welding processes, the quality of the weld is often dependent on how precisely the welding head is positioned for the seam place. If the positioning is checked by a measurement system before the welding, unnecessary rejection can be prevented right from the start. The elster company uses the scanCONTROL 2810 profile sensor for this. The position of the scanner to the valve is initially measured eight times before the welding process. The laser welding head is positioned to the seam based on these data.

The setting of the distance between the drum and the flat is crucial for carding quality of fiber, e.g. wool. Investigations have shown that manual gap settings with the gage to the left and right on the carding machine are not equal and that with the machine at standstill slight deviations from the operating conditions arise. The remedy is provided by a measuring flat rod (FCT) with two or three capacitive sensors which is exchanged for a flat rod. The sensors measure the distance to the drum via the drum width. The other distance signals are passed to the PC. The fully automatic measurement sequence eliminates erroneous settings and shortens the setup time. The inspection and documentation of the results facilitates practical quality assurance.
