About the OXY5500 Analyzer
The OXY5500 is a stand-alone precision system enclosed in a NEMA 4X and IP66
rated stainless steel case. The rugged design and low power consumption
makes the OXY5500 ready for an indoor or outdoor application in Class 1,
Division 2, Groups A, B, C and D environments according to CSA standards
CAN/CSA C22.2 No. 0-M91, CAN/CSA C22.2 No. 94.2-07 / UL50E, CAN/CSA
C22.2 No. 213-M1987, CAN/CSA 61010-1-12, ANSI/UL 61010-1, CAN/CSA
C22.2 No. 60529:05, ANSI/ISA 12.12.01 - 2007 and ANSI/IEC 60529 - 2004.
In addition, the Oxygen analyzer is also marked as II 3 G, Ex nA IIC T3 Gc
IP66 and certified according to ATEX standard EN 60079-0:2012 + A11:2013,
EN 60079-15:2010 and IECEx standard IEC60079-0:2011 Edition 6.0 and
IEC60079-15:2010 Edition 4.
The OXY5500 is designed for three types of sensor ranges; 0-300 ppmv, 0-5%

and 0-50% O

. This system was specifically designed for gas measurements
using a flow through fiber-optic oxygen sensor mounted in a 1/4” compression
tee. The instrument LCD and data-logger are integrated into the system. The
analog outputs are programmable to provide data for oxygen and temperature.
The digital interface and PC software (included) are used for internal data
storage and external data logging. Complete control, including all calibration
and adjustments, can be completed through the PC.
Temperature
SpectraSensors’ optical oxygen sensors must be used with an RTD Probe (Pt100
temperature sensor) in the temperature ranges shown in Table A–1 on
page A–1. Each instrument is supplied with the RTD probe for compensation
and to record temperature variations.
Cross-sensitivity
The sensors can be used in methanol- and ethanol-water mixtures, as well as
in pure methanol and ethanol.
SpectraSensors recommends avoiding other organic solvents, such as acetone,
chloroform or methylene chloride, which may swell the sensor matrix rendering
it unusable.
There is no cross-sensitivity issues with CO

Getting Familiar with the Analyzer
Figure 1–1 shows a sample OXY5500 analyzer. Signal wiring and analyzer
power are connected from the right side of the analyzer (facing the unit). On
the front panel of the analyzer, the LCD serves as the user interface to the
analyzer. The analyzer control electronics drive the sensor, collect the signal and
provide measurement output signals.
