Description of AF56-F / AF56-N sensors 4 Description of AF56-F / AF56-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 AF56-F / AF56-N The following are the main sensor components: Fig. 2 6 5 Schematic AF56-F / AF56-N 2 1 2 3 4 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. - 5 -

Description of AF56-F / AF56-N sensors 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 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 of a sensor body. In the technical data, OPL is always given corresponding to window combination A-A. - 6 -

It is recommended to use the supplied installation paste. Fig. 5 Installed sensor, example AF16-N / AF16-F sensor - 12 -

Installation 6.3 Airpurge Should the temperature of the process medium be too low, the temperature of the air inside the optical housing might fall below dew point. This leads to condensation deposits on the window surfaces. For that case, there are airpurge connections on the window rings of the sensor body or on the optical housings of the sensor. Note! If the product is more than 10 C (18 F) cooler than the ambient air of the sensor, always connect airpurge. Tool Screw driver wrench 7 mm At delivery, the drill holes of the air purge connections are sealed with O-Ring and sealing screws M5 x 6 (DIN 84). 1. Remove the sealing screws and O-Rings. 2. Check if there are O-Rings on air purge connections. 3. Install air purge connections (24, fig. 6) screwing. 4. Place the air purge hoses on the air purge connections (24). 4 24 24 12 24 4 12 24 Fig. 6 Window ring air purge connections (left) and optical housing air purge connections (right) After connecting the sensor to the power supply and putting it into operation, rinse it as described below: 1. Loosen the two adapters (4,12) turning each 2-3 turns anticlockwise. 2. Rinse the optical housings by aerating them with dry, oil and dust free air for approx. 10 minutes at a maximum of 0.5 bar (7.25 psi) gauge pressure. In case you do not have airpurge supply of appropriate quality, you can use the optek Air Drying System ADS. 3. Reduce air pressure to approx. 0.1 bar (1.45 psi). 4. Retighten the adapter. Keep up the gauge pressure. Air consumption in this operational state is minimal. 5. Make sure the O-Rings are fitted correctly. - 13 -

If necessary, the sensor body can remain in the pipeline so that only the optical arms and the converter have to be sent. - 19 -

Maintenance 9 Maintenance 9.1 Preventive maintenance Tab. 7 Preventive maintenance Component Maintenance activity Maintenance interval Information Wetted parts Lamp module inspection with regard to leakages exchange as part of standard installation maintenance 1-2 years Possible damaged sealing faces of the sensor body can lead to leakages (see instruction manual of the armature). Operation of the lamp below its nominal voltage (4.8 V DC instead of 5.0 V DC) enhances lamp life. Strong vibrations, high temperatures or frequent on and off switching of the system can have negative effects on the service life. Statistical service life is 3 years. Note! The used detector is not subjected to measurable aging when used properly. - 20 -
