HK1 - M

HK1-M

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- and chemical industry.

Description:
The microwave measurement devices generate an electromagnetic wave of low energy. This signal is coupled via an antenna into the product.

Depending on the dielectric properties of the product the signal propagates in the product. After the signal has passed the product a second antenna receives the signal (Transmission).

Amplitude and phase shift of the received signal are an expression for the water content or dry matter of the product.

The microwave measurement is very stable and it has a quick response to product changes.
Transmissions signal passes through
an in-homogenous product

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