Ahlborn FHA696 GF1 moisture sensors

The Ahlborn FHA 696 GF1 sensors can be used for determining the moisture content in granulated materials. Some examples of the materials include wood chips or pellets, sawdust, cereals and various types of grains. The sensor operates based on the principle of an open plate capacitor. Moisture content in the materials can be determined based on the dielectric constant of the materials.

The FHA696 offers quick determination of moisture content in a matter of seconds. To get an accurate reading, measurements need to be made in the sealed air-tight package filled with approximately 10 L of granulated sample. The readings are compared with the reference data, which is measured on dried samples. These reference values are programmed into the ALMEMO connector for the moisture probe.

This sensor is suitable for measuring the moisture content of hydrophobics material. It can measure from 0 to 99.9% of moisture based on its weight percentage with 0.1% resolution. The FHA696 works in conjunction with other measuring instruments from ALMEMO for data display and monitoring.
