HK4 NIR spectralyser

HK4  

Measurement of up to 4 organic componentes

  • simultaneous online- mesaurement of up to 4 organic componentes (e.g. fat, water, protein, connective tissue protein)
  • specially developed NIR (Near InfraRed) technology with diode array and therefore the first online NIR- spectrometer.
  • modular setup of evaluation unit and halogen sensor
  • transmission or reflection halogen sensor
  • no drift of the measurement values through aging of the lamps
  • independend of color changes
  • no moving parts


Trophy 2006    Innovation award:
The NIR-online-spectrometer HK4 was awarded by CFIA in France with the highest trophy measurement instruments can get in the food industry. At present the HK4 is the only online-spectrometer, to be used in raw process environment, not only in laboratories. The HK4 is developed with the latest online NIR technology with diode array and therefore directing in NIR technology.

Depending upon operational area different sensors are available.

HK8

HK8-Belt  

NIR-H2O-Meter

Unique LED- online moisture measurement

  • state of the art NIR-LED technology
  • no mechanically moved parts
  • specially designed for measuring of bulk material
  • the measured surface can be smooth, planar or bulk material
  • Colour has no influence on the measured signal
  • no maintanance
  • easy to use calibration software


The HK8 is a device for continuous NIR reflection measurement with infrared LED's. The NIR-H2O-Meter is a modular unit, evaluation and sensor system are mounted in different housings. The distance between sensor system and product can be up to 50 meters.

The measured value of the H2O content is available as digital (RS232, optional RS485) and analogue value (0/4-20mA).

Advantages:
In contrast to conventional IR or NIR systems from other suppliers, the HK8 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. Colourvariations of the product has no influence in the measuring result. Also uneven surfaces of the product, such as coarse bulk materials, can be measured. The HK8 has a very high reliability and very low maintenance costs.

Measurement Design:
The sensor system is located over the detected product surface. The products (e.g. paper webs, width of material and any kind of bulk material) are moving on a conveyor belt under the sensor system.
Messprinzip

Applications:
all kind of bulk material

  • Plastics industry
  • Primary industry
  • Construction industry
  • Tobacco indutry
  • Sugar industry
  • Cement
  • Gravel
  • Coal
  • Granitic sand
  • Clay
  • Plastic granulate

Calibration:
The calibration of the HK8 is done with our easy to use Specter8 software.

HK8-mini

HK8-MINI  

Unique NIR- LED technology

  • continuous online moisture measurement
  • no moving parts
  • specially designed for continuous online measuring of moisture/ TS in liquide products in pipes or tanks
  • in large pipes or tanks the sensor is penetrating the product. On small pipes the sensor is flanged on a sight glass
  • Colour has no influence on the measured signal
  • no maintanance
  • easy to use calibration software


The HK8-mini is a device for continuous NIR reflection measurement with infrared LED's. The NIR-H2O-Meter is a modular unit, evaluation and sensor system are mounted in different housings. The distance between the sensor and the evaluation unit can be up to 50 meters.

The HK8-mini is a further development of our proven HK8. It was specifically designed to dive into large pipes or to be flanged via a sight glass on a small pipe.
The measured value of the H2O content is available as digital (RS232, optional RS485) and analogue value (0/4-20mA).

Advantages:
In contrast to conventional IR- or NIR-systems of other suppliers, the HK8-mini is not equipped with colour filters or halogen bulbs. The used LED illumination cares for an improved stability with a lifetime of 10 years.

Measurement Design:
The sensor is either completely inserted into the product (flange in large pipes or a tank), or attaches through a sight glass.

Depending on customer requirements, the fitted sight glass or HK8-mini sensor can be equipped with borosilicate glass or sapphire.

HK8-mini with a flange:

HK8 mini mit Flansch
HK8-mini mounted on a sight glass:

Tuchenhagen


Applications:
The HK8- mini is a complimentery instrument to our microwave moisture measurements (or dry solids) in pipes and tanks where our microwave measurement won't work due to different disturbances (salt, PH value...)


Conceivable applications:

  • Milk industry
  • Paper industry
  • Mozarella
  • Cream cheese
  • Butter
  • consistency measurement
