Distance and position measurement - Import export

Particular Challenge: For the assessment of rotating parts, numerous parameters have to be taken into consideration: Concentricity, radial run-out and axial run-out (i.e. wobble); furthermore thickness, diameter, planarity and the absence of surface defects had to be examined. The solution developed by QuellTech consists in a configuration of three Q6 Laser Laser Scanners.Each of the lateral surfaces is assigned to its own scanner. In order to enable the thickness precisely to be determined, both laser lines are mutually oriented in opposite direction. The third scanner inspects the outer circumference of the wheel, this way measuring diameter and radial run-out. All of these scanners are subject to encoder signals supplied by the rotary axis and synchronously triggered, so possible defects on the wheel can precisely be localized. The measurement takes place at a resolution of ca. 30 µm, and a cloud comprising several millions of points are obtained.

The high-performance optoNCDT ILR2250 laser distance sensor is used whenever large measuring ranges and high accuracy are required. The optoNCDT ILR2250 can be installed at distances up to 100 m, and even up to 150 m with a reflector film. This sensor impresses when measuring dark, structured and poorly reflecting surfaces, while providing stable measurement results to millimeter accuracy. The optoNCDT ILR2250 laser distance sensor is used in transportation, logistics and conveyance technologies as well as automation and the metals industry. This is where the sensor enables reliable measurement results even when it is, e.g., installed at a safe distance from heat emitting measuring objects. In addition, difficult-to-access places via mirrors or through glass sheets can be detected.

Draw-wire sensors of the wireSENSOR series measure almost linearly over the entire measuring range and are used for distance and position measurements between 50 mm and 50,000 mm. Draw-wire sensors from Micro-Epsilon are ideal for both direct integration and subsequent assembly in serial OEM applications, e.g., in medical devices, lifts, conveyors and automotive engineering.

The optoNCDT 1900 offers a unique combination of speed, size, performance and application versatility for displacement, distance and position measurements. This compact triangulation sensor achieves a high measurement accuracy and measuring rates of up to 10 kHz. The high-performance optical system generates a small light spot which enables to even detect the finest of details and structures reliably.

The capaNCDT DT61x4 is an active, capacitive system for displacement, distance and position measurements. Consisting of a sensor with integrated preamplifier, a robust cable and a compact controller, the measuring system is immediately ready for use without any on-site calibration. The measuring system is available with a cable length up to 15 m and is ideal for automation purposes. The capaNCDT 61x4 is particularly suitable for automated robot manufacturing and measurement tasks with a drag chain. Moreover, it is used in machine building and semiconductor production. For optimum signal quality, the desired cable length is already factory-calibrated.

The optoNCDT 1320 is a new laser triangulation sensor with compact size for displacement, distance and position measurements. Due to its extremely compact size including integrated controller, the sensor can also be integrated into restricted installation space. Its low weight make the optoNCDT 1320 ideally suitable for applications where high accelerations occur, e.g., on the robot arm or in pick-and-place machines. The optoNCDT 1320 offers high accuracy and adjustable measuring rates up to 4kHz. The Active Surface Compensation (ASC) provides stable distance signal control regardless of target color or brightness. Very small objects can be detected reliably due to the small measurement spot size.

The optoNCDT1420 offers a unique combination of speed, size, performance and application versatility for displacement, distance and position measurements. The compact triangulation sensor achieves a high measurement accuracy and measuring rates of up to 8kHz. The selectable connector type, i.e. cable or pigtail, together with compact size reduce the sensor installation effort to a minimum. Just like all triangulation sensors from Micro-Epsilon, the optoNCDT 1420 provides an intelligent surface regulation. The Active Surface Compensation (ASC) ensures stable measurement results regardless of changing surface colours or brightness. The high-performance optical system generates a small light spot which enables to even detect smallest components reliably.

White light interferometers use infrared light in the non-visible range (approx. 840 nm wavelength), which means that the measurement position cannot be seen. To visualize the measuring position, Micro-Epsilon systems are equipped with a pilot laser which projects a light spot onto the measuring position. In addition, the pilot laser uses a patented method to provide feedback on the distance in addition to the measurement position. If the measuring object is at the correct distance and within the measuring range, a constant glow is emitted by the pilot laser. If the measuring object is outside the measuring range, the pilot laser flashes.
