3 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 segmentoptimized withrespectto flow andsterilerequirements.Two
different optical path lengths in combination with an extensive range of
accessories offer maximum flexibility for adaptation to the process.

1. Optical path length (OPL)
2. Sapphire window
3. Lamp
4. Optics module with filter
5. Detector
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.
