Product description

The HK9 microwave measuring device is based on advanced microwave technology and enables fast and precise measurement of the bulk density and moisture of bulk goods and bales on conveyor belts. It transmits a low-power electromagnetic wave via an antenna into the measured product (such as paper, tobacco, sand, etc.), which propagates depending on the dielectric properties of the product. A second antenna receives the transmitted wave (transmission). The power of this wave is used to determine the water content or bulk density of the product.

Thanks to its fast response time and stable microwave measurement, the HK9 is suitable for continuous process monitoring in production. It is calibrated by the user-friendly Specter9 software, which enables simple and effective handling.

What sets the HK9 apart

Latest microwave technology

The HK9 uses the most advanced microwave technology for measuring bulk density and moisture. This technology ensures precise and reliable measurement at high speed.

Modular, compact design

The modular design of the HK9 enables flexible installation and integration into various production environments, even in confined spaces.

Maintenance-free and wear-free

The device works without moving parts, which minimizes wear and tear and reduces maintenance to a minimum over a long period of time.

Insensitive to vibrations

Vibrations, which could falsify measurement results in other industrial environments, have no influence on the measurement accuracy of the HK9.

Non-contact measurement for fast results

The HK9 measures moisture and bulk density-dependent properties of the products without contact, at a speed of up to 10 measurements per second, which significantly increases the efficiency of the production process.
