HK2-M

HK2- M

concentration- and moisture measurement

state of the art microwave engineering
optional guard for rough conditions
wear-free
maintenance-free
vibrations do not have an influence on the result of measurement
optional remote control from a PC or separate operating device
optional automated sensor cleaning

The microwave measuring instrument HK2-M is particularly designed for the sugar,- sewage plant- and building material 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

Conditions for a successful measurement:
The product contains NO SALT and there is NO METAL between the antennas!

The HK2-M is using our Spiral antennas or Pin antennas, where an optional cleaning could be included.

We advise you gladly which antennas for which application or measuring kind the best results supply.
