2 Returns and disposal
2.1 Declaration of decontamination
For the safety of our employees and because of legal regulations we need a
signed “declaration of decontamination” before your return can be handled.
This signed declaration must be included with the shipping documents on the
outside of the packaging.
Any returns which were exposed to hazardous substances and were not
professionally decontaminated are not accepted and will be sent back on your
cost.
optek’s declaration of decontamination and contact information can be found on
our website www.optek.com.
2.2 Disposal
Special legal regulations apply to the return and disposal of industrial waste
equipment. However, manufacturer and user can contractually agree on which
party is to fulfill these legal obligations.
Observe current national disposal regulations.
To dispose packaging material, please separate materials into the following
groups:
• Paper / paperboard
• Plastic
For disposal, disassemble the system components and separate them
according to different material groups.
Dispose of materials according to national and local regulations.
If no agreement has been made, products may be shipped to optek for disposal.

3 Intended use
The optek-sensors AF16 and their variants are to be applied only as absorption
sensors for liquids and gases in inline applications according to the technical
data.
The use of the sensors in hazardous locations is prohibited. You can purchase
flameproof sensors for hazardous locations from optek. For these sensors,
special instruction manuals are delivered with the sensor.
Unauthorizedconstructionalchanges, additionalfittingsorrebuildings regarding
the sensor are prohibited. The only exception are rebuildings into one of the
variants listed in the chapter "Validity of the instruction manual". Changes to and
interference with the converter program are prohibited as well.
To lay sensor cables underground without protection is prohibited.
The manufacturer is not liable for damage resulting from misuse.
Following this instruction manual is part of the intended use.

4 Description of AF16-F / AF16-N sensors
This sensor is a high precision absorption sensor. It measures attenuation of
light passing through the process medium. The sensor was designed for direct
installation into pipelines.
Fig. 1 AF16-F / AF16-N
The following are the main sensor components:
Fig. 2 Schematic AF16-F / AF16-N
1. Sensor body
2. Windows
3. Filter (VIS or NIR)
4. Detector
5. Optics module
6. Lamp module
Its modular construction offers maximum flexibility in adapting to the process,
without affecting the property of measurement. A precisely defined, constant
light beam penetrates the process medium. A hermetically sealed silicon
photodiode measures intensity of incoming and optically filtered light and
supplies the converter with it in form of photocurrent.

Description of AF16-F / AF16-N sensors
- 6 -
optek-Manual--1004-2001-02--AF16-US-2011-01-04
www.optek.com
Attenuation of light intensity, as a result of absorption and / or scattering of
substances in the process medium, is described by the Lambert-Beer Law. It
states, the logarithm of the transmission loss is proportional to concentration of
the substance. This is true for dissolved substances and undissolved material.
Depending on the particular material properties, concentrations can be detected
in ppm as well as in %.
According to this law, the extinction coefficient, defined through ingredient and
wavelength, affects the logarithm of the transmission loss, too. Therefore, the
choice of wavelength or range of wavelengths is of decisive importance for the
measurement and is defined for each measurement type with the help ofoptical
filters.
The third factor of influence in the Lambert-Beer Law is the path length of light
passing through the process medium. Equally proportional, the path length, too,
is an important aspect with regard to specification of a photometer. The distance
to be covered by light is defined through the optical path length (OPL), that is the
distance between the windows of a sensor body. In the technical data, OPL is
always given corresponding to window combination A-A.
