Operational Theory

2.1Principles of Operation

The sub-systems that make up the analyzer are:

1.Micro-Fuel Cell Sensor

2.Sample System

3.Electronic Signal Processing

The Micro-Fuel Cell sensor is an electrochemical galvanic device that translates the amount of oxygen present in the sample into an electrical current. The sample system delivers the sample gas in a form that is as unaltered as possible for testing, and for leak-free transport of gases through the analyzer.

The electronic signal processing unit (control module) is designed to simplify the operation of the analyzer and accurately process the signal from various components. The control module incorporates a microprocessor which allows the operation of the analyzer with a minimum of operator interaction. Figure 2-1 illustrates major components.
