Physical principles

Measurementprinciple

Oxygen is highly paramagnetic and this differentiates it from nearly all other gases.The molar susceptibility of a paramagnetic gas is temperature-dependent. It isinversely proportional to the absolute temperature.This fact, and the property of paramagnetic substances to be drawn to areas ofhigher field strength in a non-homogeneous magnetic field, form the basis for O2

measurements.

The sample gas is brought into the field of a strong permanent magnet. If thesample gas contains oxygen it is drawn to areas of higher magnetic field strength.At this point in the magnetic field there is an electrically heated wire, the measuringresistor, that warms the surrounding sample gas. Warming decreases theparamagnetism of the sample gas so that the sample gas is forced out of themagnetic field and colder gas can flow in after it. This forms a flow pattern knownas "magnetic wind".

The measurement resistance is highly temperature-dependent and changesaccording to the flow rate of the magnetic wind. A reference resistance is found inthe other half of the chamber which is not in the magnetic field. The ratio betweenthe sample and reference resistance depends on the strength of the magneticwind, i.e. on the concentration of oxygen in the sample gas.

The measurement and reference resistance values are connected to a Wheatstonemeasuring bridge via two temperature-independent resistors.Compensating the Wheatstone bridge by means of the temperature-independentresistors leads to an unbalance voltage that is digitized and linearized in thedownstream electronic circuits and is then available as a measurement signal.

SHB_M17 Chapter 1: Description of functions 1-3

Physical principles, Continued

Signal processing • The sample chamber measurement signal (unbalance voltage) is passed to thesensor electronics board and digitized there by an A/D converter.

• The digitized measurement signal is passed to the Sensor-CPU board for

processing with the data contained in the EEPROM. • The measurement value can be recorded or processed further (e.g. as an mA

signal in the central processor electronics) via an RS232 interface or via theinternal bus.

1-4 Chapter 1: Description of functions SHB_M17

Determination of influence values

Temperature • The analyzer is located in a thermostatically controlled chamber at a constanttemperature of 61 ±2°C.

• The temperature sensor is on the support board and reads the chambertemperature.The temperature sensor is an NTC resistor.

• Any thermostat temperature deviation from the set temperature is processed asa status message.The temperature control circuit is on the Sensor-CPU board.

Flow rate • The flow rate through the sample chamber should be approx. 20-60 l/h. It canbe monitored, e.g. by a flow rate sensor, in the pneumatics module for example.

Flow Rate Monitoring • The composition of the accompanying gas must be known and taken intoconsideration during initial calibration.

Accessories • PC with serial interface• Advance Optima - masserv - test and calibration software• Serial interface connection cable part number 0743091• Test gases, test hoses• Flow meter

Preparation • Check gas path seal integrity• Make electrical connections• The analyzer module should be installed in the area of application and

Test • Test all detectors (the measurement values must be stable and regularlyupdated)

• Status message 0 for all detectors

Performing the initialcalibration

+

Analyzer-calibration should be performed individually for each componentand each of its measurement ranges.

An initial calibration resets the subsequent substitute gas and commoncalibration for this component. Thus it also affects the settings of othermeasurement ranges!

Zero- and end-pointcalibration with thePC

+

Before balancing the zero- and end-point gases, carry out the same preparationmeasures and test as for initial calibration.

A zero- and end-point balance can be carried out if the sensitivity reserve hasexceeded the permissible value. The original linearization is maintained during thisbalancing. The calibration data established are written to the EEPROM asconstants.

If several components and / or several measurement ranges are set-up andthe components/measurement ranges are subsequently calibrated usingsubstitute gas or common calibration, all components/measurement rangescalibrated together must be considered when balancing the zero- and end-points.
