Teledyne Analytical Instruments
Thermal Conductivity Analyzer Part I: Control Unit
Introduction
1.1 Overview
The Model 2010 is a family of split conguration conductivity analyz-
ers. Each analyzer consist of a Control Unit suitable for installation in a
general purpose area, and a Analysis Unit which is housed in an explosion-
proof enclosure. The Analysis Unit enclosure is rated for NEMA 4/7 Class
I, Div. 1, Groups B,C,D and is approved by U/L and CSA.
The Analytical Instruments Model 2010A Thermal Conductivity
Analyzer is a versatile microprocessor-based instrument for measuring a
component gas in a background gas, or in a specic mixture of background
gases. It compares the thermal conductivity of a sample stream with that of
a reference gas of known composition. The 2010A can—
• measure the concentration of one gas in a mixture of two gases.
• measuretheconcentrationofagasinaspecicmixtureofback
-
ground gases.
• measure the purity of a sample stream containing a single impu-
rity or a mixture of impurities.
The standard 2010A is pre-programmed with automatic linearization
algorithms for a large number of gases and gas mixtures. The factory can
add to this data base for custom applications, and the sophisticated user can
add his own unique applications.
This manual section covers the Model 2010A General Purpose ush-
panel and rack-mount control units only. These control units are for
indoor use in a nonhazardous environment.
Many of the Model 2010A features covered in this manual are op-
tional, selected according to the customers specic application. Refer to the
specic model information sheet (page IV) for the options incorporated in
the instrument.
