  • Page 11: Introduction

    INTRODUCTION INTRODUCTION The XZR400 Series Trace Oxygen Analyzer is designed to measure oxygen as an inpurity in nitrogen, carbon dioxide, argon, helium or other inert gases. Analysis is both quick and stable, utilizing our metallic sealed reference sensor (MSRS), with no requirement for reference air.

  • Page 12: Operating Principle

    XZR400 Series User’s Manual INTRODUCTION The XZR400 Series includes the following front panel mounted items: • Liquid crystal touchscreen display • Flow adjustment valve • Bypass control valve Operating Principle The analyzer operates on the zirconium oxide (zirconia) principle. A sample of the gas to be measured is connected to the inlet port of the analyzer. The sample gas fl...

  • Page 13: The Msrs Technology

    XZR400 Series User’s Manual INTRODUCTION The MSRS Technology The zirconium oxide sensors are often referred to as the ‘high temperature’ electrochemical sensors. The principle is based on the Nernst principle [W. H. Nernst (1864-1941)]. Zirconium oxide sensors use a solid state electrolyte and are stabilized with yttrium oxide.

  • Page 14: Figure 2 Msrs Sensor

    XZR400 Series User’s Manual INTRODUCTION Figure 2 MSRS Sensor Conventional zirconium oxide sensors require an air reference on one side of the sensor with the sample on the other. This provides a known constant on one side. The Michell MSRS does not require an air reference but instead utilizes a metal, and its oxide, sealed in the zirconium sheath.

  • Page 15: Table 1 Xzr400 Series Msrs Assembly

    XZR400 Series User’s Manual INTRODUCTION Figure 5 shows the MSRS and its S thermocouple installed in a 4-hole aluminum tube. This confi guration has the part number XZR400-SMP. Any reference to the MSRS sensor refers to this complete assembly which is considered solid state and non user-serviceable.
