AF16-EX-N Single Channel NIR Absorption Sensor |
 |
The model AF16-EX-N is a precise, single channel NIR
absorption sensor designed especially for hazardous
environments. The AF16-EX-N is used for inline applications
in a variety of industrial processes. |
The modular sensor consists of a flameproof stainless steel
lamp housing and an intrinsically safe detector module.
The appropriate converter can be located either in a safe
area or in a flameproof or pressurized enclosure directly in
the hazardous location. |
The AF16-EX-N uses the light in the near infrared range (NIR)
from 730 to 970 nm and measures concentration or turbidity
with great accuracy and repeatability. A precisely defined,
constant light beam penetrates the process medium. |
The attenuation of the light intensity, caused by absorption
and/or scattering by dissolved and undissolved substances
in the medium, is detected by a hermetically sealed photo
diode. |
Optical path lengths (OPL) are available from 1 to 1000 mm
for process versatility. The special optical sapphire window
provides superior resistance to all abrasive and corrosive
media. |
The AF16-EX-N is available with a broad variety of line sizes,
process connections and wetted materials. NIST-traceable
validation accessories assures absolute measurement
confidence. |
