AF16-N Single Channel NIR Absorption Sensor |
 |
The model AF16-N is a single channel Near Infrared (NIR) absorption sensor. The inline sensor is designed for a variety of industrial processes. The AF16-N measures concentration or turbidity with great accuracy and repeatability and can be used in demanding applications such as filter control, phase separation, and yeast cell concentration. |
The AF16-N uses light in the NIR from 730 to 970 nm, making the measurement independent of color influences. 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 the light intensity is a function of the concentration of the undissolved and dissolved substances in the process medium. The AF16-N typically measures parts per million (ppm) and percentage (%) ranges.
|
The single crystal sapphire optical window provides superior resistance to all abrasive and corrosive media. The AF16 –N is available with a broad variety of line sizes, process connections and wetted materials and can be adapted easily to the process. NIST-traceable validation accessories assure absolute measurement confidence. Options for hazardous area classification are also available. |
