Consistency measurement

HK1 - M

HK1-Mp  

Concentration- and moisture measurement

  • sate of the art microwave engineering
  • modular setup of evaluation unit and sensors
  • no moving parts
  • no wear
  • vibrations do not have an influence on the result of measurement
  • maintenance-free
  • optional remote control from a PC or separate operating device
  • up to 16 different calibrations
  • temperature sensor PT100 is standard, optional NTC possible



Due to the robust and modular design the microwave measuring instrument HK 1-M is particularly suitable for the measurements of concentration and water content in the food- , primary and chemical industry.


Depending upon operational area following antennas are used: We advise you gladly which antennas for which application or measuring kind the best results supply.

HK8-mini NIR-H2O-Meter

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.

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
