Page 7: Structure Of The Uv Sensor
Overview NiCaVis 70x IQ NI Structure of the UV sensor A UV sensor contains 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. - Page 8 Overview NiCaVis 70x IQ NI 1 - 4 ba75988e01 11/2012...
