SpectraSensors Overview
SpectraSensors, Inc. is a leading manufacturer of advanced electro-optic gas
analyzers. Headquartered in Houston, Texas, SpectraSensors was incorpo-
rated in 1999 as a spin-off of the NASA/Caltech Jet Propulsion Laboratory
(JPL) for the purpose of commercializing space-proven measurement technol-
ogies initially developed at JPL. SpectraSensors was acquired by the Endress
+ Hauser Group in 2012.
About the Gas Analyzers
The SS500e/SS2000e/SS3000e are tunable diode laser (TDL) absorption
spectrometers operating in the near- to short-wavelength infrared. Each
compact sensor consists of a TDL light source, sample cell and detector
specifically configured to enable high sensitivity measurement of a particular
component within the presences of other gas phase constituents in the stream.
The sensor is controlled by microprocessor-based electronics with embedded
software that incorporates advanced operational and data processing
algorithms.
Sample conditioning system
A sample conditioning system is included with the system that has been
specifically designed to deliver an optimum sample stream that is
representative of the process systems stream at the time of sampling. Most
SS500e/SS2000e/SS3000e analyzer systems are configured for use at
extractive natural gas sampling stations. Refer to “Sample Conditioning
System” on page 4-1 for more information.
Differences between the SS500e, SS2000e, and SS3000e
The SS500e and SS2000e are single-channel analyzers used predominantly for
measuring H
2
O or CO
2
in pipeline natural gas. The SS2000e is a higher
resolution version of the SS500e (for performance specifications, see Table A–1
on page A–1, Table A–2 on page A–2, Table A–3 on page A–3 or Table A–4 on
page A–4). The SS3000e is a dual-channel version of the SS2000e and is
usually configured to measure H
2
O and /or CO
2
in the same or separate
pipeline natural gas sample streams (for performance specifications, see
Table A–5 on page A–5). Refer to the following chart for an illustration of
possible system configurations for the SS3000e
