NIR PROBE NIR PROBE MOUNTED ON VESSEL
HK8
NIR-H2O-Meter
|
Range of Application
Infrared measurement in the range of NIR for the detection of only H2O
(moisture, water content, total/dry solids) in products on conveyor belts.
The meter is sufficient for products with a smooth and planar surface as
well as for abrasive bulk material. |
|
Principle
This infrared measurement technique irradiates the surface of the product
with illumination from infrared LEDs.
The measured data, generated by reflection, are evaluated by the HK7 system.
The evaluation detects every H2O molecule, with an absorption
line in the spectrum of measurement
Functionality
Continuous NIR reflection measurement with infrared LEDs. The
NIR-H2O-Meter is a compact unit, evaluation and sensor system are mounted in
the same housing.
The evaluation takes place in the peak areas as follows: 970, 1200, 1800 and
2200 nm. The distance between sensor system and product is approx. 200mm.
The measured value of the H2O content is available as digital and
analogue value.

Measurement Design
The sensor system is located 200mm over the to be detected product surface.
The product surface can be smooth and planar, or bulk material. The products
(i.e. cement, plastic granulate) are moving on a conveyor belt under the
sensor system.
Applications
The number of feasible applications is limited to bulk material in the
primary and construction industry.
Conceivable applications:
- Plastics industry
- Primary industry
- Construction industry
- Cement
- Gravel
- Coal
- Sand
- Clay
- Plastic granulate
Advantages
In contrast to conventional IR- or NIR-systems, the HK8 is not equipped with
color filters or halogen bulbs. The use of LED's enables improved stability
with a lifetime of 10 years.
