Description:
The microwave resonance measurement uses the electromagnetic energy stored
inside a resonator to determine the water content of a product.
Via a non conducting window, the resonator field is coupled into the material located
in front of the resonator. This so called leakage field is not radiated.
Depending on the dielectric properties of the product, the shift of resonance
frequency and bandwidth of the resonator is used for measurement.
The ratio of bandwidth and frequency shift is density independent. The measurement is highly
suitable for bulk material.
Resonance Measurement
Due to the sensor’s distance dependency it is recommended to place the sensor
as close as possible to the product, the measured values are available as %H2O.
