Operational Theory
Overview
There are five main analyzer functional groups:
1. Ultra Trace Sensor
2. Faradaic Calibrator
3. Sample System
4. Electronic Signal Processing
5. Temperature Controller.
The analyzer uses a sophisticated Ultra Trace oxygen (O
2
) sensor, which is an
electrochemical galvanic device with current output.
An electrochemical calibrator based on Faraday’s law is provided to facilitate
the calibration of the analyzer.
The sample system is designed to optimize the performance of the analyzer.
The components and the methods used for the fabrication of the sample system
assure 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.
A temperature controller regulates the temperature of the Ultra Trace sensor
to minimize the effects of ambient temperature variations during analysis.
Figure 2-1 shows the locations of the major components of the analyzer.
