Teledyne Analytical Instruments Part II: 1-1
Thermal Conductivity Analyzer Part II: Analysis Unit
Introduction
1.1 Overview
The Analytical Instruments Model 2010A Analysis Unit is a versatile
remotely controlled instrument for measuring a component gas in a back-
ground gas, or in a specific mixture of background gases.
Part 1 of this manual covers the Control Unit. Part II, this part, covers
the Model 2010A NEC type explosion proof Analysis Unit only.
1.2 Connections
The standard 2010 Analysis Unit is housed in a NEC type housing and
includes all gas connections. Figure 1-1 is a cutaway illustration of the
Analysis Unit showing the Gas Connections. The gas connectors are de-
scribed briefly here and in detail in the Installation chapter of this manual.
NOTE: The version of the 2010 Analysis Unit depicted has no options.
The gas connections found on the 2010A Analysis Unit depend on the
options selected. Refer to the outline diagram in the rear of this manual for
the actual configuration. These options may include gas panels with
flowmeters and auto-cal or manual valves as well as flame arrestors. If you
have purchased a unit with a sealed air option, there will not be any refer-
ence gas connections or flowmeter. If you have not purchased a unit with
gas panel, provision must be made to provide zero and span gas to the
sample in port.
• SAMPLE IN This is the gas input from the sample stream.
This gas connection should have a flowmeter
with a range of 50-200 cc/min.
