MESAX 70 multi-spot - laser distance sensor

Stable distance measurement on shiny & extremely coarse surfaces

With the new multi-spot laser distance sensor of the MESAX family, Baumer presents an innovative and compact measuring unit for measuring on critical surfaces - even under substantial ambient light conditions.

The compact sensor provides exact and reproducible measuring results without any complicated conversion or external software. The MESAX multi-spot sensor is the ideal solutions for a large number of applications in measuring and testing technology.

Your advantages:

- Stable, reproducible measurements, even on non-homogeneous glossy and extremely coarse surfaces.
- High measuring accuracy even under varying ambient light conditions  
- Fast installation and start-up of the calibrated sensor
- Compact measuring system without complicated external software.

Distance measurement on shiny surfaces

With non-homogeneous glossy objects, the light of a laser spot reflected from the surface does not always find its way back to the optical receiver. Thanks to the multi-spot technology with over 500 measured values, there is generally enough distance information in the sensor to be able to carry out precise measurement of the distance in “Average" mode.  In this way, glossy preformed parts can also be measured accurately during quality inspection.

Distance measurement on extremely coarse surfaces

Distance measurements on very rough surfaces always represent a challenge. Multi-spot sensors record a large number of distance values over a defined measuring range. The sensor then calculates a precise mean value for such applications. In this way, for example, grinding disks with rough surfaces can be optimally positioned in relation to a workpiece. In this case, the measuring range can be restricted. Measurement is effected using the “Average" mode. The distance value recorded by the sensor with an absolute accuracy of less than 0.1 mm is used directly in the controller of the CNC machine.

The multi-spot measuring principle – a new level of precise distance measuring

The innovative multi-spot measuring principle by Baumer is based on optical sectioning. Up to 600 measuring values of an object are determined per measurement in the sensor, and from these values the distance is calculated using the intelligent evaluation process. Thanks to its resolution of up to 2 µm or 0.008% of the measuring range at a measuring frequency of 500 Hz, the sensor offers stable and precise measurement results.
