Microwave moisture analyzers work on the principle that water has a very high dielectric constant compared to most other materials. When microwaves intersect with water molecules
within the material they slow down (and hence change phase) and weaken (attenuate) as the energy is transferred to the material.The LFM3 moisture analyzer has a low profile antenna, which
transmits a beam through the material on the conveyor belt. The signal is received by a receiver patch located below the conveyor belt. The received signal is compared to the transmitted signal for phase and amplitude change.The methodology and electronics used to detect these signal changes are part of the analyzer’s proprietary technology
