Operational Theory 
2.1 Introduction 
The analyzer is composed of two subsystems: 
1.  Oxygen probe 
2.  Control unit with signal processing, display and controls 
The oxygen probe can be heated or unheated. It delivers the sample 
gas to a state-of-the-art zirconium sensor which translates the amount of 
oxygen present into a millivolt output. 
The control unit processes the sensor output and translates it into 
electrical concentration, range, and alarm outputs, and a percent oxygen 
meter readout. It contains a micro-controller that manages all signal 
processing, input/output, and display functions for the analyzer. 
2.2 Oxygen Probe, Sensor, and Heater  
TI/AI oxygen probes and sensors employ state-of-the-art zirconia 
sensors and advanced materials. They provide the following benefits:  
•  Improved control due to fast response time—typically less than 
four seconds.  
•  Cost-efficient design provides improved reliability. 
•  Longer-life probes with greater resistance to corrosion from 
sulphur and zinc contaminants in a flue gas. 
•  Low cost replacement reduces maintenance. 
•  Reduced probe breakage due to greater resistance to thermal 
shock and mechanical damage during installation and startup.  
 
The 9060L probes or sensors are simple to install and maintain. All 
models provide direct measurement of oxygen level. Figure 2-1 shows a 
typical oxygen probe. Probe specifications are listed in the Appendix of 
this manual and installation is covered in Section 3.
