<p>The probes miniaturised detectors, for the detection of physical-chemical parameters, are grouped inside circulation cells of the fluid to be examined. These cells have windows formed in the thickness of a tube support eventually using the axial light of the liquid circulation tube. The tube may be rigid, flexible or supple. The detection system consists of several stages of miniaturised detectors each detecting a specific parameter. Probe analysis is made by continuous simultaneous measurement or by a programmed pulse regime switching between detectors to give measurements of: optical density of materials in suspension, over several wavelengths. temperature and pressure. PH, Po2, T ,Redox, humidity in the milli-second domain. fluid speed. fluid clarity by means of photo-conductors coupled to an external spectro-photometer.</p> |
