Structure of the sensor NitraVis 70x IQ
The sensor has a light source (1), a measuring gap (3) to enable the contact of
light with the measuring solution, and a detector (5) to measure the attenuated
light beam.
The sender of the optical system (2) directs a light beam, the measuring beam
(6), through the measuring solution and a second light beam, the reference
beam (8), over a distance without measuring solution. The test sample is
between both measurement windows (3) in the measuring gap.
The receiver of the optical system (4) directs the measuring beam and reference
beam to the detector. In the detector, the light is received by fixed photo diodes.
