Page 6: Device Description
Device description Viomax CAS51D Device description Sensor design The sensor is designed as a 40 mm sensor that can be operated directly and completely in the process without the need for further sampling (in situ). One version of the sensor measures the amount of nitrate in the medium while another version measures the SAC value of the medium. - Page 7 Viomax CAS51D Device description NPT “ ¾ 40 (1.57) A0031311 3 Sensor with 40 mm gap width, dimensions in mm (inch) Endress+Hauser...

Page 8: Operating Principle
Device description Viomax CAS51D Operating principle 3.3.1 Measuring principle The light from a pulsed, high-stability strobe lamp (item 3) passes through the measurement section (item 2). A beam splitter (item 6) directs the light beam to the two receivers (items 1 and 5). A filter upstream from the receivers only lets through light in the measuring wavelength or reference wavelength. - Page 9 Viomax CAS51D Device description 3.3.2 Nitrate measurement The sensor is designed for measuring nitrate. As nitrite is also measured, it could also be regarded as an NO sensor. Nitrate ions absorb UV light in the range of approx. 190 to 230 nm. Nitrite ions have a similar absorption rate in the same range.
- Page 10 Device description Viomax CAS51D The ratio to SAC (based on KHP) is calculated as follows: 1/m = 1.487 mg/l COD = 1.487 mg/l BOD = 0.595 mg/l TOC = 0.595 mg/l DOC Many components that absorb light at 254 nm deviate significantly from KHP in terms of their absorption behavior.
