2D Camera-Based Cross-Section Light Scanner for Width Measurement

The VIS/2D sensors from ELOVIS work on the basis of non-contact edge sensing transversely to movement direction of the measurement object in light reflection or transmitted light. The accurate measurement in the transverse light sensor is used for production monitoring, process optimization and documentation of the delivery status of the produced goods. VIS/2D systems are maintenance-free, permanently calibrated and measure largely independent of material. As a kind of “optical micrometer” VIS/2D systems are used for cross-section measurement, width, height, diameter determination of strips, profiles, tubes, plates, beams, bolts, rolls made of different materials.

Mobile Equipment

Measurement Tripod


The µMETER-X sensors are lightweight and therefore very well suited for mobile measurement in conjunction with the ELOVIS tripods (TRI). The TRI tripod consists of: tripod, boom with joint, sensor attachment to the boom with ball head and sensor mounting plate.


PC Software


The CMS configuration and monitoring software is used for µMETER-X operation, adjustment of setpoint and tolerance values as well as the display and storage of measurement values on a PC, laptop or tablet computer. The CMS software is mainly used for manual measurements.

Fieldbus and Communication Modules

Profibus-DP, ProfiNet-RT, Ethernet-IP


Standard bus interface modules with the following output: Measurement Value (in m) , Speed (in m/s), Status Signal (valid/invalid)

2D Camera-Based Cross-Section Light Scanner for Width Measurement

The material to be measured passes through the measurement area across the conveying direction of the µMETER-X System in longitudinal direction. As soon as the material is located on the same height as the sensor, the corresponding cross-sectional dimension is automatically and continuously determined. To ensure that the measurement can take place with high accuracy, the measurement material has to be as clean and dry as possible. In addition, the measurement object should pass the µMETER-X system as straight as possible. The measurement principle can be described as optical micrometer / measuring cross-section light scanner for measurements in the production cycle. The µVIS-2D system is based on shading of a reflector by the measuring material.
