Theory Of Operation Teledyne ML - T100 UV Fluorescence SO2 Analyzer
242 06807A(DCNxxxx)
9.5.2. SENSOR MODULE
Electronically, the T100 sensor module is a group of components that: create the UV
light that initiates the fluorescence reaction between SO
2
and O
3
; sense the intensity of
that fluorescence; generate various electronic signals needed by the analyzer to
determine the SO
2
concentration of the sample gas (refer to Section 9.1.1), and sense
and control key environmental conditions such as the temperature of the sample gas and
the PMT.

These components are divided into two significant subassemblies: the sample chamber
and the PMT assembly.
Figure 11-13 shows an exploded view of the sample chamber assembly
