Non-contact measurement & inspection

IntuItIve 3D Data CapturIng

Laser DIstanCe sensor targets objeCts up to 150m away

measures distances up to 150m with an accuracy of < ± 1mm. The sensor measures accurately even on difficult surfaces such as dark, structured or weakly reflecting objects. Without any special adaptations to the target, the sensor has an impressive range up to 100m. Adding a reflector to the target extends the range to 150m. Developed in-house by Micro-


Epsilon, the new optoNCDT ILR2250-100 laser distance sensor is both smaller and more accurate than its predecessor, the optoNCDT ILR1181. The factory default AUTO measurement mode allows precise and reliable measurements to be made on targets over great distances. Additional modes are also available to tune the sensor to specific application requirements. Protected by an IP65 die cast

aluminium housing, the optoNCDT ILR2250-100 is suitable for a wide range of applications, from transport, logistics and conveyor systems, to automation, metal processing, production monitoring and unmanned drones or vehicles. It has already found uses in monitoring large coil diameters, silo filling levels and gantry cranes. The combined long range and high accuracy of the sensor has also found particular benefits in the measurement and control of diameters for hot ring rolling. In terms of its technical

performance, the sensor is unsurpassed in its field, providing excellent repeatability (<300µm), resolution (0.1mm) and linearity (< ± 1mm), resulting in extremely stable measurements and excellent

signal stability. The sensor’s small footprint (102 x 53 x 50mm) and weight (254g) represent a 65 per cent reduction in size and weight compared to its predecessor, allowing it to be easily installed in narrow or restricted spaces in production lines and machines. The optoNCDT ILR2250-100

provides four basic modes of operation. AUTO mode is the factory default setting where the speed (measuring rate) can be varied between three to 20Hz, depending on the target. FAST mode has a reduced accuracy of ± 1mm and requires a ‘good’ surface. ACCURATE mode is suitable for targets moving up to 1.5 m/s. PRECISE mode has an accuracy of 0.3mm. Glenn Wedgbrow, business

development manager at Micro- Epsilon comments: “Rather than use the time-of-flight measuring principle like our previous sensor models, the optoNCDT ILR2250- 100 operates on the phase comparison measuring principle. This method confirms the distance measurement more accurately and works well in smoke, steam and fog. In addition, due to its compact footprint and configurable software, the sensor can also be adapted to meet individual OEM requirements.” The optoNCDT ILR2250-100 can

provide continuous measurement output via a 16-bit, scalable, 4-20mA analogue output or via RS422 serial communication. Three digital switch outputs are available for simple process monitoring and a trigger input provides opportunities to control when the sensor takes a reading.


data in an easy and intuitive way - even in the most hard- to-reach areas. Combined with the pre-installed GOM Inspect Suite software, the lightweight and hand-held laser scanner T- SCAN, the optical tracking system T-TRACK and the touch probe T-POINT deliver measurement results for a wide range of applications. With its mobile and modular concept, the laser scanning system

creating full digital twins is easy and intuitive with T-SCAN. The system is equipped with the pre-installed GOM Inspect Suite, which is an established standard in many industries and supports all inspection tasks from scanning through to inspecting and reporting.

Mobile systeM with Modular concept

In combination with the optical tracking system ZEISS T-TRACK, T- SCAN measures in any dimension. Users can choose between two versions of T-TRACK: The new T-TRACK 10 for smaller measuring volumes of 10 m3

20 for large measuring volumes of up to 20 m3 , the all-new ZEISS T-TRACK 10 can now be combined with the

he ZEISS T-SCAN system helps users to obtain highly precise 3D

and higher accuracy or the established T-TRACK . In just one setup, T-

TRACK 10 can measure parts of up to 2.5 m in length, T TRACK 20 of up to 4 m in length. The traceable accuracy guarantees reproducible and reliable measuring results. The hand-held touch probe T-POINT is ideally suited to perform single-point measurements on object surface areas such as edges and standard geometries or optically hard-to-reach areas. T-SCAN can capture 3D data even on vibrating or moving objects.

If a part is too large for the T-TRACK or its geometry blocks the line of sight, Spherical Mounted Targets (T-SCAN SMTs) ensure the precision of the captured data. The SMTs can be easily mounted on the measured object and allow for extended measuring volumes.

wide range of applications

Not only shop floor inspections are now easier with T-SCAN – the measuring system supports all quality control and inspection areas. Thanks to T-SCAN, users benefit from precise 3D data and easy inspections from product development and design through to tool and mold making.

Many inspection features for free

With its all-in-one GOM Inspect software, 3D metrology specialist GOM has become a standard in many industries. GOM’s new software platform GOM Inspect Suite embraces and facilitates the complete workflow from scanning to reporting for maximum ease of use. GOM Inspect Suite offers a host of inspection features and is available for free after registration. The full version of GOM Inspect Suite provides the full extent of data analysis and template capabilities.
