Returns and disposal
2 Returns and disposal
2.1 Declaration of decontamination
For the safety of our employees and because of legal regulations we require 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 at 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. For disposing of packaging
material, please separate materials:
• paper/cardboard
• 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.

Intended use
3 Intended use
The sensor and its variants are to be applied only as absorption sensors for
liquids and gases in inline applications according to the technical data.
Use 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.
Unauthorized constructional changes, additional fittings or rebuildings 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.
Burying sensor cables underground without protection is prohibited.
The manufacturer is not liable for damage resulting from use contrary to the
intended use.
Following this instruction manual is part of the intended use.
The content of all serial number plates on optek products is model-specific and
refers to the time of delivery.

Description of AS56-F / AS56-N sensors
4 Description of AS56-F / AS56-N sensors
This sensor is a high precision absorption sensor designed for direct installation
into pipelines and vessels. It is of compact and robust construction with a
measuring segment optimized with respect to flow and sterile requirements. Two
different optical path lengths in combination with an extensive range of
accessories offer maximum flexibility for adaptation to the process.

3 Lamp 4 Optics module with filter
5 Detector
The process medium is penetrated by a precisely focused, constant light beam.
A hermetically sealed silicon photodiode measures intensity of incoming and
optically filtered light and supplies the converter with it in form of photocurrent.
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 that the logarithm of the transmission loss is proportional to the
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 of optical
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 in the measuring segment of the sensor. The OPL
of your sensor is given on its serial number plate.
