Photoelectric 3D level measurement and point level detection
3D sensors with PMD technology
- Continuous measurement of uneven surfaces
- Determines min, max or mean values
- Teaching of different tank shapes
- Interfering structures are suppressed
- Non-contact detection of opaque media for levels of up to 10 m
The system detects solid, opaque solids and bulk materials in tanks, silos or hoppers with levels of up to 10 m. The O3D reliably detects the load height in machinery for mechanical handling, e.g. belts, and the loading of pallets. The sensor determines the level via a defined background and transmits the process value via analogue output or digitally and noise immune via the Ethernet process interface. Alternatively, the O3D may be used as a point level switch.
The measuring segment of the sensor can be adapted to the shape of the respective tank. Agitators and other attachments can be suppressed via “exclusion regions”. Various container shapes, such as hoppers, silos or even inclined belts can be recognised by the sensor.
This means that for bulk materials the average level is indicated, even if there are conical heaps or funnelling.
