Load tests on airplane wings

In order to optimize the behavior of wings during a flight, the wings are already subjected to vibration tests during the construction. 120 wireSENSOR draw-wire sensors are connected to the wing and synchronized. In this way, any change of the wing form in the vertical direction can be tracked.

Planness measurement of display glass

Thinnest glass of outstanding flatness is required for the production of displays for telecommunications equipment. During glass production measuring and monitoring of the flatness is a decisive factor for quality inspection. The results of these measurements can be used for optimizing the pro-duction process. On a high-precision hard rock table in the measuring room samples of these thinnest glass plates are measured by laser-optical triangulation sensors with an accuracy of 5 μm.

Deflection/cambering of steel strips and saw blades

In the production and processing ne of metal strips, numerous measurement variables need to be monitored, e.g. straightness, cambering and deflection. The inspection of these quantities is carried out using three optical micrometers. The two outer laser micrometers form a straight line. The middle one measures the deviation and therefore the deflection to this straight line. The position of the sheet edge in the laser beam is not important here as long as the edge is within the beam path of all the three micrometers.

System for testing the risk of creaking with combinations of materials

Ziegler Instruments in Mönchengladbach, Germany develops  and  manufactures  test  systems  that  are  able  to predict the risk of creaking noises due to stick-slip vibrations. In this way, the movement of different material combinations relative to each other - so-called „stick-slip“ - can be examined. For example, a passenger car driving for 100,000km can be simulated in the laboratory in just a few hours.

Measurement system for cut packaging pieces

Manufacturers in the packaging industry make high demands with regard to their production quality. For sampling inspection for example, the cut pieces of packaging are extracted from the production, placed in a measurement system and a nozzle system draws them down flat by suction. A non-contacting triangulation sensor scans the surface to measure the topography of the cardboard and to determine the line of the grooves, edges and the associated lengths to high accuracy.

Flatness measurement in rolling mills

The requirements on the surface quality of rolled sheet metal are continually increasing. This may be steel sheet which is used, for example, for stainless steel fronts in kitchens, or also aluminum sheet used in the automotive field. The surface must be flawless to offer the customer a high quality visual appearance. Consequently, measurement equipment is employed in rolling mills to acquire the so-called flatness of the rolled sheet metal. Flatness is taken to mean the surface evenness of the sheet in the unstressed state.

Flatness inspection on ceramic wall tiles

In the production of ceramic wall tiles or similar products, a one hundred percent quality inspection is essential. Three laser triangulation displacement sensors measure the deflection of tiles with an accuracy of 0.1 μm. Separate specification values can be entered for concave or convex deflections.

Monitoring the clamping of tools

Modern, high performance machine tools are now achieving accuracies of just a few micrometers or even less. Such precision can only be achieved by optimum matching of all components, starting with the drive, then the release unit, tool clamp through to the tool itself. Since most components are permanently installed on the machine, then with correct installation the highest precision can be achieved. The only problem is that the tool is changed with each new phase of the operation and can therefore cause critical deviations.

Machine tool clamping position

An inductive sensor according to the VIP principle is used for displaying the movement of the clamping cylinder in machine tools. The sensor is integrated in the clamping device and determines the axial position of the clamping cylinder. The displacement signal is routed to a control unit which provides programmable switching points. The outputs of the clampCONTROL control unit can be used in a downstream machine or system controller.
