Operational Theory

1.1Introduction

The analyzer is composed of three subsystems:

1.Paramagnetic Sensor

2.Sample System

3.Electronic Signal Processing, Display and Control

The sample system is designed to accept the sample gas and transport it through the analyzer without contaminating or altering the sample prior to analysis. The Paramagnetic Sensor is an electromechanical device that translates the amount of oxygen present in the sample into an electrical signal. The electronic signal processing, display and control subsystem simplifies operation of the analyzer and accurately processes the sampled data. The microprocessor controls all signal processing, input/output and display functions for the analyzer.

1.2.1 Principles of Operation

The heart of the 3010M is a paramagnetic type oxygen sensor that is maintanance free and has a long lifetime. Oxygen has a very high magnetic sucseptibility compared to other gases and thus displays a particularly para- magnetic behavior. A small glass dumbbell filled with nitrogen and rotating on a taut platinum wire is suspended in an inhomogneous magnetic field. This glass dumbbell is diamagnetic and tends to rotate out of the magnetic field. The strength of the resulting torque determined by an susceptibility of the sample gas. This torque is compensated for by a counter torque induced by an electrically charged platinum coil on the dumbbell. The zero position of the dumbbell is controlled by means of an optical system consisting of a light source, a mirror at the dumbbell axis and a pair of detectors. The difference between the compensating currents required to bring the dumb-
