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.
