Continuous online-measurement at bulk material
- state of the art NIR-LED technology
- continuous online- measurement of 2 components (water- and/or fat content)
- no moving parts
- specially designed for measuring of bulk material
- the measured surface can be smooth, planar or bulk material
- Color has no influence on the measured signal
- no drift of the measured value due to lamp aging
- no maintenance
- MTBF of the NIR- LED`s is 10 years
- easy to use calibration software
The HK3 is a continuous NIR reflection measurement with infrared LED's. The LED-NIR-Spectrometer HK3 is a modular unit, evaluation and sensor system are mounted in
The distance between sensor system and evaluation can be up to 50 meters.
The measured values are available as digital RS232 (or optional RS485) output and analogue value (0-20 or 4-20 mA).
In contrast to conventional IR or NIR systems from other suppliers, the HK3 does not work with
color filters or halogen lamps, and offered therefore improved stability of the measurement. The lifetime is up to 10 years. The drift of the
measurement value, as is the case with other IR / NIR instruments, has been fully compensated. Color variations of the product have no influence on the measuring
result. Also uneven surfaces of the product, such as coarse bulk materials, can be measured. The HK3 has a very high reliability and very low maintenance costs.
The sensor is mounted over the product surface. The product (e.g. paper webs, width of material and any kind of bulk material) is moving on a conveyor belt under the sensor system.
The calibration of the HK3 is done with our easy to use Specter3 software.
