Teledyne Analytical Instruments 1-2
1 Introduction Model 2020
1.2 Typical Applications
A few typical applications of the Model 2020 are:
• Power Generation
• Air liquefaction
• Chemical reaction monitoring
• Steel manufacturing and heat treating
• Petrochemical process control
• Quality assurance
• Refrigeration and storage
• Gas proportioning control.
1.3 Main Features of the Analyzer
The main features of the Model 2020 Thermal Conductivity Analyzer
include:
• Three independent, user definable, analysis ranges allow up to
three different gas applications with one concentration range
each, or up to three concentration ranges for a single gas appli-
cation, or any combination.
• Special recalibration range for multiple applications. Recalibrat-
ing one, recalibrates all.
• Automatic, independent linearization for each range.
• Auto Ranging allows analyzer to automatically select the proper
preset range for a given single application. Manual override
allows the user to lock onto a specific range of interest.
• RS-232 serial digital port for use with a computer or other
digital communications device.
• Six adjustable set points concentration with two alarms and a
system failure alarm relays.
• Extensive self-diagnostic testing, at startup and on demand.
• Sample and Hold for holding analyzer’s output during Auto
calibration mode.
• A 2-line alphanumeric display screen, driven by microprocessor
electronics, that continuously prompts and informs the operator.
