Trace Oxygen Analyzer Introduction Teledyne Analytical Instruments 1 Introduction 1.1 Overview The Teledyne Analytical Instruments Model 3000ZA Trace Oxygen Analyzer is a versatile mi croprocessor-based instrument for detecting oxygen at the parts -per-million (ppm) level in a variety of gases.
Introduction 3000ZA-3X Teledyne Analytical Instruments 2 Three Zirconium oxide sensor s to provide higher range of analysis flexibility. The analyzer can cover ranges as low as 0-10 ppm or as high as 0-95%. No reference gas required Versatile analysis over a wi de range of applications.
Trace Oxygen Analyzer Introduction Teledyne Analytical Instruments 3 switch between gases in synchronization with the analyzer’s operation. 3000ZA-M: This model has current output signals (4-20- mA) for ppm range and range ID, in addition to voltage outputs.
Introduction 3000ZA-3X Teledyne Analytical Instruments 4 Function Keys: Six touch-sensitive m embrane switches are used to change the specific function performed by the analyzer: Analyze Perform analysis for oxy gen content of a sample gas. System Perform system-related tasks (described in detail in chapter 4, Operation.
Trace Oxygen Analyzer Introduction Teledyne Analytical Instruments 5 Standby Button : The Standby turns off the display and outputs but circuitry is still operating. CAUTION: THE POWER CABLE MUS T BE UNPLUGGE D TO FULLY DISCONNECT POWER FROM THE INSTRUMENT.
Introduction 3000ZA-3X Teledyne Analytical Instruments 6 Power Connection Universal AC power source. Gas Inlet and Outlet One inlet (must be externally valved) and one exhaust out. Three inlets when option “C” is ordered. 9-Pin RS-232 Port Serial digital concentration signal output and control input.
Trace Oxygen Analyzer Operational Theory Teledyne Analytical Instruments 7 Operational Theory 2.1 Introduction The analyzer is composed of three subsystems: 1. Three Zirconium Oxide (ZrO 2 ) Sensors. Each one has a specific range of analysis: Low range sensor of 0-200 ppm, medium range sensor of 0-2 %, and high range sensor of 0-95%.
Operational Theory 3000ZA-3X Teledyne Analytical Instruments 8 One of the three sensors has been modified (0-200 ppm range) to sense low levels of oxygen—less than 1 ppm and generate a current proportional to the concentration. The sensor is designed for long term stability and an operating life of 5 years.
