HK1 - Mc


Concentration- and moisture- measurement in cheese

  • state of the art microwave engineering
  • particularly designed for the measurement of cheese
  • optional height measurement of the cheese
  • vibrations do not have an influence on the result of measurement
  • wear-free
  • maintenance-free
  • optional remote control from a PC or separate operating device

Our microwave measuring instrument HK1-Mc is particularly designed for the measurement of the water content of cheeseblocks on a conveyer belt.

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.
