Moisture measurement on perforated bricks

Berthold‘s measuring systems are successfully in use at Wienerberger, specifically on the clay conveyor belt for Poroton®. Horn antennas are used under and above the conveyor belt to transmit a microwave signal. When retrofitting existing conveyor systems, spiral antennas can also be used if necessary.

The moisture measuring principle

The microwave measuring system uses the special dielectric property of water. The measuring system generates microwaves that interact with the water molecules. This interaction causes an attenuation of the microwave energy, which can be detected as phase shift and attenuation. Since the phase shift and attenuation are directly proportional to the water content in the product, the concentration the medium can be determined with high accuracy.
Berthold‘s superior multi-frequency technology ensures very stable and reliable measurements that are unaffected by interfering reflections or resonances. The microwave power of a measuring system is so low (max. 10 mW) that the material to be measured is neither heated nor changed in any way.
