The optional sample conditioning system (SCS) contains flow devices for the
bypass loop and to control the flow to the oxygen sensor. A pressure reducing
device is also installed to reduce the pressure of the sample going to the
oxygen sensor. Depending on the application and/or ambient conditions, the
SCS may also contain a heater and thermostat to maintain the interior of the
enclosure at a constant temperature. Refer to the Sample Conditioning System
(SCS) Overview Manual for more information.
Housing for Oxygen in Natural Gas
SpectraSensors’ fiber-optic oxygen sensors are made with 2 mm polymer
optical fibers. The sensing portion is a 4 mm stainless steel probe. As a
standard, the probe is mounted in a 1/4” Swagelok Union Tee using a 1/4” x
4mm adapter as shown in Figure 1–3. Custom designs are also available.
Please contact your sales representative for more information.

Oxygen Probe
The oxygen sensor consists of a polymer optical fiber (POF) with a polished
distal tip that is coated with a planar oxygen-sensitive foil. The end of the
polymer optical fiber is covered with a high-grade steel tube to protect both the
sensor material and the POF. Refer to Figure 1–4. Typically, the fiber is coated
with an optical isolated sensor material in order to exclude ambient light from
the fiber tip.

Introduction
Figure 1–5 Trace oxygen probe schematic
This probe has a very rugged sensor with excellent long-term stability (more
than 100000 data points without drift) and is usable for process applications.
How does an oxygen sensor work?
The principle of measurement is based on the effect of dynamic luminescence
quenching by molecular oxygen. The following scheme explains the principle of
dynamic luminescence quenching by oxygen.
Principle of dynamic quenching of luminescence by molecular oxygen (refer to
Figure 1–6):
• Luminescence process in absence of oxygen (1)
• Deactivation of the luminescent indicator molecule by molecular
oxygen (2)
The collision between the oxygen-sensitive material in its excited state and the
quencher (oxygen) results in radiation-less deactivation and is called collisional
or dynamic quenching. After collision, energy transfer takes place from the
excited indicator molecule to oxygen which consequently is transferred from its
ground state (triplet state) to its excited singlet state. As a result, the indicator
molecule does not emit luminescence and the measurable luminescence signal
decreases.

the analyzer will come mounted on a plate or Unistrut frame. Refer to
Appendix A for drawings with detailed mounting dimensions.
When mounting the analyzer, be sure not to position the
instrument so that it is difficult to operate adjacent devices. Allow
1 m (3 feet) of room in front of the analyzer and any switches.
It is critical to mount the analyzer so that the supply and return
lines reach the supply and return connections on the chassis while
still maintaining flexibility so that the sample lines are not under
excessive stress.
Mounting brackets for equipment intended to be mounted on a
wall and/or part/s that support heavy loads shall withstand four
times the maximum static load.
To mount the analyzer:
1. Select a suitable location to mount the analyzer. Choose a shaded
area or use an optional analyzer hood (or equivalent) to minimize
sun exposure.
SpectraSensors analyzers are designed for operation within the
specified ambient temperature range. Refer to Appendix A.
Intense sun exposure in some areas may cause the analyzer
temperature to exceed the maximum range.
2. Locate the mounting holes on your unit. Refer to Figure 2–1 and the
system drawings in Appendix A.
3. For wall installations, mark the centers of the top mounting holes.
Mounting dimensions are shown in Appendix A.

Installation
Careful consideration should be taken when grounding. Properly
ground the unit by connecting the main ground lead to the
protecting grounding stud labeled with the ground symbol .
Connect the chassis ground stud to plant grounding using 6mm2
or 10-gauge wire.
Do not exceed the 36 VDC power rating or electronics will be
damaged.
Interconnection of the analyzer enclosure shall be accomplished
using wiring methods approved for Class 1, Division 2 hazardous
locations as per the Canadian Electrical Code (CEC) Appendix J
and the National Electric Code (NEC) Article 501. The installer is
responsible for complying with all local installation codes or in
accordance to ATEX/IECEx standards IEC/EN 60079-0, IEC/EN IEC/EN
60079-15 and IEC/EN 60079-14.
Protective chassis and ground connections
Before connecting any electrical signal or power, the protective and chassis
grounds must be connected. Requirements for the protective and chassis
grounds are as follows:
• The protective and chassis grounds must be of equal or greater size
than any other current-carrying conductors, including the heater
located in the sample conditioning system.
• The protective and chassis grounds must remain connected until all
other wiring is removed.
• If the protective and chassis ground is insulated, it must use the
green/yellow color.
Refer to Figure 1–1 and Figure 1–2 for the protective and chassis ground
locations.
To connect electrical power to the analyzer:
1. Open the OXY5500 analyzer electronics enclosure door. Take care
not to disturb the electrical assembly inside.

2. Run conduit or armored braided cable from the power distribution
panel to the conduit hub on the right side of the analyzer enclosure
labeled for power input.
Conduit seals or Ex e cable gland should be used where
appropriate in compliance with local regulations.
Because the breaker in the power distribution panel or switch will
be the primary means of disconnecting the power from the
analyzer, the power distribution panel should be located in close
proximity to the equipment and within easy reach of the operator,
or within 10 feet of the analyzer.
The electrical installation to which the apparatus is connected
must be protected against transients. The protective device has
to be set at a level not exceeding 140% of the peak rated voltage
values at the power supply terminals.
An approved switch or circuit breaker rated for 15 amps should be
used and clearly marked as the disconnecting device for the
analyzer.
3. For AC systems, pull ground, neutral (N) and L1 wires into the
electronics enclosure. Refer to Figure 2–2.
For DC systems, pull VI +, – and ground wires into the electronics
enclosure. Refer to Figure 2–2.
4. Strip back the jacket and/or insulation of the wires just enough to
connect to the power terminal block.
5. Connect the main ground wire to the protection ground terminal
marked .
6. Close and tighten the analyzer enclosure door.
Apply 20 in-lbs of torque on each bolt to ensure the door is closed
properly to maintain required ingress protection.

Connecting the Analog Outputs/Analog Inputs
The OXY5500 is equipped with two independent analog outputs and one analog
input. The 4-20 mA current loop and serial output are connected terminal
blocks located inside the analyzer electronics enclosure. By default, the 420mA current loop analog outputs (IOUT1/IOUT2) are set to inactive.
The analog outputs are programmable to oxygen and temperature. To allow
external data collection, one input port is available (i.e., external pressure
sensor).
A protective device (miniature circuit-breaker or circuit breaker)
and a disconnection unit for the power supply must be installed.
SpectraSensors recommends using a line-side miniature circuit
breaker (IEC 898): Characteristic B from 16 A or Characteristic C
from 10 A.
Connections can be made with customer-supplied cables for the current loop
and alarms. Consult the wiring diagram in Figure A–2 on page A–4.
Certified Ex e glands and cables, or conduit seal and conduit,
should be used where appropriate in compliance with local
regulations.
