RFM1000 Penetrative Radio Frequency Moisture Sensor.
The RFM-1000 Radio Frequency Moisture Sensor generates a Radio Frequency Fringe Field at less than 10 MHz. This field penetrates into the product being measured. As the total water content of the measured product changes, the RFM-1000 quantifies the resultant shift in frequency. This frequency shift is converted into a high resolution digital count value, directly proportional to the change in percentage total moisture. This operation is performed continuously at 200 measurements per second.
