3.1 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.
The sensor comprises the following assemblies:
• Power supply
• High-voltage generation for the strobe lamp,
• Photometer cuvette
central component in which the measuring light interacts with the medium.
• Detectors,
detect the measuring signals, digitize them and process them to form a measured value.
• Controller,
responsible for controlling internal sensor processes and transmitting data.
All data - including the calibration data - are stored in the sensor. The sensor can be
precalibrated and used at a measuring point, calibrated externally, or used for several
measuring points with different calibrations.
