AF56-F Single Channel Absorption Sensor |
 |
The model AF56-F is a single channel absorption sensor designed for inline applications. It accurately measures color or color changes and can be used in a variety of industrial processes, from sanitary CIP/SIP applications to high-pressure, high-temperature industrial applications. |
The AF56-F sensor uses the light in the visible (VIS) range from 400 to 480 nm at selected wavelengths. A precisely defined, constant light beam penetrates the process medium. The attenuation of the light intensity, caused by absorption and/or scattering by substances in the medium, is detected by a hermetically-sealed silicon photo diode. |
The change of light intensity is a function of the concentration of dissolved and undissolved substances in the process medium. The AF56-F is typically used to determine precise color or color changes. An optical filter adapts the wave length for an individual application (i.e. phase separation beer/water) at a specific wave length between 440 nm - 480 nm. |
The single crystal sapphire optical window provides superior resistance to all abrasive and corrosive media. The AF56-F is available with a broad variety of line sizes, process connections and wetted materials and can be adapted easily to the process. |
