Automated, high-precision inline quality assurance of complex components
3D laser scanning is a powerful, non-contact measurement process for the fast and high-resolution acquisition of complex geometries. Harrandt Automation integrates 3D laser scanners specifically into assembly, testing, and automation systems to measure components close to the process and with high repeatability.
In 3D laser scanning, a laser projects a line or a pattern onto the component. A camera captures the reflected line, from which a precise height profile is calculated using triangulation. The relative movement between the sensor and the workpiece creates a complete three-dimensional point cloud or a surface model.
This process is particularly suitable for:

Where standard cameras reach their limits, line scan camera technology is just getting started. It is the ideal industrial image processing tool for inspecting objects in continuous motion or at extremely high speeds.
The functional principle: Frame by frame to perfection
In contrast to a conventional area scan camera, a line scan camera only records a single light-sensitive sensor line, often several thousand pixels wide. The complete, two-dimensional image is only created by the relative movement between the camera and the test object (e.g. on a conveyor belt or a rotation axis). These lines are strung together at an extremely high frequency, creating a seamless, high-resolution image.

Precise, non-contact geometry measurement using spectral light evaluation for demanding industrial surfaces
When it comes to the highest precision in measuring surfaces, layer thicknesses, and geometries, chromatic confocal measurement technology offers a powerful solution. Whether coating thicknesses, surface structures, or complex geometries such as gears – we develop and integrate the right solution for your measurement task.
How does the process work?
In chromatic confocal measurement technology, a polychromatic light source is focused onto the measurement object via special optics. Only the wavelength that is exactly focused on the surface is reflected back towards the sensor and evaluated. The exact distance to the surface can be determined from the detected wavelength.
The measurement process thus enables high-precision, non-contact distance measurements even with demanding surfaces and small structures.
Your advantages at a glance:
Every measurement task places different requirements on the sensor system and system design. That is why we do not just look at the individual measured value, but at the entire process.
You describe your measurement task to us, and we develop a suitable solution from it.
Contact us if you would like to measure surfaces, coatings, or complex component geometries precisely and without contact.
In modern manufacturing and quality assurance, “accurate” is often no longer enough. When it comes to tolerances in the nanometre range, interferometric measurement is the gold standard of non-contact measurement technology.
How does the process work?
Interferometry uses the wave nature of light. A laser beam is split into two paths: one part hits a reference object, the other hits the workpiece to be tested. When the reflected beams meet, an overlay pattern (interference) is created. Even the smallest deviations in the surface structure change this pattern so characteristically that we can measure unevenness that lies far below the wavelength of light.
Your advantages at a glance:
With our expertise in interferometry, we ensure the quality of your most demanding coating projects so that you can rely on the results.
Ultrasonic pulse measurement: Non-destructive testing of internal structures
When external vision is not enough to assess the integrity of a component or material, ultrasonic pulse measurement is the tool of choice. As a precise, non-destructive testing method, it allows us to make internal structures visible and to determine material properties exactly.
The measurement principle: Echo instead of intervention
The process uses high-frequency sound waves that are sent through the test object. If these pulses hit interfaces – such as the back wall of a component or a defect inside – they are reflected. By precisely measuring the transit time and the intensity of these echoes, the exact position of defects can be determined or the material thickness can be measured to the nearest micrometre.
Your advantages at a glance:
Whether in production control or during the periodic inspection of plants, we provide you with the data that is decisive for the safety and longevity of your products.
When it comes to the non-contact detection of positions, distances, or material properties, inductive measurement is the backbone of industrial sensor technology. Wherever dirt, oil, or moisture push other measurement systems to their limits, induction delivers reliable and high-precision data.
The functional principle: The power of magnetic fields
The heart of an inductive measurement system is a coil that generates a high-frequency alternating magnetic field. If a metallic (conductive) object approaches this field, eddy currents are created within it. These draw energy from the field, which is registered by the sensor and converted into a precise electrical signal. In this way, the distance to the object can be determined to the nearest micrometre without ever touching the component.
Your advantages at a glance:
From simple end-position control to complex layer thickness measurement, we offer you inductive measurement technology that works exactly where it matters.
Where the human eye only sees the surface, infrared measurement makes thermal processes and temperature distributions precisely visible. As one of the most versatile non-contact measurement methods, it is indispensable for monitoring machines, quality control, and energetic analysis.
The measurement principle: Heat as a data signal
Every object with a temperature above absolute zero emits infrared radiation. Our sensors and thermal imaging cameras capture this invisible radiation and convert it into exact temperature values. Since the measurement is passive and non-contact, even rotating parts, components under voltage, or very hot surfaces can be analysed safely and in real time.
Your advantages at a glance:
Whether for optimising your manufacturing processes or for securing your plant availability, we make heat flows visible and help you to use potentials efficiently.
In the world of quality assurance, tactile measurement technology remains the measure of all things when it comes to the exact acquisition of complex geometries. While optical processes can reach their physical limits, tactile probing delivers incorruptible data directly from the workpiece surface.
The measurement principle: Precise acquisition through contact
In tactile measurement, a highly sensitive probe head, usually equipped with a diamond tip, traces the contours of the component. Every point of contact is coordinated in space with the highest precision. Whether through single-point probing or continuous scanning, our system captures diameters, distances, form, and position tolerances down to the sub-micrometre range. Even reflective surfaces or deep bores that are difficult for light to access do not pose an obstacle for our tactile sensors.
Your advantages at a glance:
We combine state-of-the-art coordinate measurement technology with many years of experience to ensure that your components correspond exactly to the specifications. For quality you can measure and feel.
Where electrical energies flow, the integrity of the insulation is the vital basis for humans and machines. High-voltage testing is the decisive process for guaranteeing the dielectric strength and electrical safety of your components under extreme conditions.
The measurement principle: Stress test for the insulation
In this test, the component is subjected to a defined high voltage far beyond its normal operating voltage. The goal is to track down weak points in the insulation that could lead to dangerous short circuits or arcs in regular operation. We precisely measure the leakage current. If this remains within the narrow tolerance limits, electrical isolation is ensured and the product is ready for use.
Your advantages at a glance:
We test your products with state-of-the-art measurement technology so that safety is not just a promise for you, but a measurable reality.
In modern quality assurance, eddy current testing is one of the most efficient methods for non-destructive material testing. It enables us to track down even the smallest cracks or material changes on the surface and just below it in seconds, without direct contact with the component.
The measurement principle: Electromagnetic interaction
The process is based on the principle of electromagnetic induction. A current-carrying coil generates a primary magnetic field that induces eddy currents in the electrically conductive test piece. These currents in turn generate a counter-field. If the eddy currents hit a fault such as a crack, a pore, or a change in the structure, this field changes characteristically. Our sensors capture these deviations immediately and provide precise conclusions about the material integrity.
Your advantages at a glance:
We use eddy current technology to guarantee the safety of your components – quickly, cleanly, and with the highest repeatability.
Differential pressure measurement with air gauge plug
Differential pressure measurement with an air gauge plug enables fast and high-precision testing of diameters and geometries, especially for bores and internal contours.
During the measurement process, the air gauge plug is inserted into the bore to be tested. An air flow is introduced into the measurement area via defined air nozzles. The resulting pressure or pressure difference changes depending on the distance between the nozzle and the workpiece. The respective geometry can be precisely determined from this pressure change.
