INTRODUCTION
1.1 OVERVIEW
This manual describes the Paramagnetic Detector (PMD) Analyzer Module of Rosemount
Analytical's NGA 200 Series of gas analysis components.
The PMD Analyzer Module is designed to continuously determine the concentration of
oxygen in a flowing gaseous mixture. The concentration is expressed in ppm or percent
volume O2.
The entire Analyzer Module is designed as a slide-in module (if configured in stand-alone
instrument fashion), removable from the front of the Platform, with gas connections made
from the rear. All electronics relative to sample detection and conditioning are included in
this module.
1.2 TYPICAL APPLICATIONS
1
PMD Analyzer Module applications include:
• process control
• continuous emissions monitoring systems (CEMS)
• industrial gas production
• fermentation process monitoring
1.3 THEORY OF TECHNOLOGY
Oxygen is strongly paramagnetic (i.e., capable of becoming a temporary magnet when
placed in a magnetic field) while most other common gases are weakly diamagnetic (i.e.,
tend to be non-magnetic). See Figure 1-1.
The Magnetic susceptibility of the flowing gas sample is sensed in the detector/magnet
assembly. As shown in Figure 1-2, a dumbbell shaped, nitrogen -filled, h ollow gas test body
is suspended on a platinum/nickel alloy ribbon in a non-uniform magnetic field.
Because of a "magnetic buoyancy" effect, the spheres of the test body are subjected to
displacement forces, resulting in a displacement torque proportional to the magnetic
susceptibility of the gas surrounding the test body.
Measurement is accomplished by a null-balance system, whereby the displacement torque
is opposed by an equal and opposite restorative torque. The restoring current is
automatically maintained at the correct level by an electro-optical feedback system. A beam

of light from the source LED is reflected off the square mirror attached to the test body onto
a bi-cell (dual photodiode).
The current required to keep the test body to the null position is a linear function of the total
magnetic susceptibility of the sample gas.
See Figures 4-1, 4-2, and 4-3 for component configuration.

1.4 FEATURES
Among the features incorporated into the PMD Analyzer Module is a flow splitter (≈2:1)
that allows for greater sample flow, decreased lag time and faster analyzer response.
The "Time Alignment" feature can be used to delay sending the Primary Variable from
the PMD Analyzer Module for up to 30 seconds in 0.1 second intervals. This feature
allows Primary Variables form more than one PMD Analyzer Module to be "time
aligned" if necessary.

INSTALLATION
2.1 UNPACKING
If the Paramagnetic Analyzer Module is received as a separate unit, carefully examine the
shipping carton and contents for signs of damage. Immediately notify the shipping carrier if
the carton or contents is damaged. Retain the carton and packing material until all
components associated with the Analyzer Module are operational.
2.2 ASSEMBLY
If the Analyzer Module requires assembly with other components (e.g., the Platform and
associated I/O Modules), do so at this time. Following the guides on the bottom left and
bottom center of the Platform, carefully slide the Analyzer Module halfway into place.

WARNING: HAND INJURY HAZARD
Do not place hands or fingers in the Platform front handles when front panel is
open. Dropping the front panel of the Platform while hand or fingers are inside
either handle can cause serious injury.

INSTALLATION
Lift the spring-loaded pins on the front of the Analyzer Module, and carefully slide it the rest
of the distance. Secure the module in position by releasing the pins, which seat in the
available holes in the bottom of the case (see Figure 2-1). If the module and Platform are
difficult to assemble, remove the module, ensure the top cover of the module is firmly
seated on the hold-down screws, and repeat the assembly procedure.
Install I/O Module(s) according to guidelines in the I/O manual. After startup and calibration
have been performed, secure the front panel with the six screws provided.
2.3 LOCATION
Install the Analyzer Module in a clean, non-hazardous, weather protected, vibration free
location free from extreme temperature variations. For best results, either install the module
near the sample stream to minimize sample transport time or supply a flow greater than
necessary and route only the appropriate amount through the Analyzer Module.
Observing these requirements are critical. Note the following:
• Excessive vibration can cause a noisy readout. To minimize vibration effects, the
detector/magnet assembly is enveloped in a shock-mounted compartment.
• The user should ensure, when making any internal electrical connections, that no
cables are placed in contact with the detector assembly or associated internal sample
inlet and outlet tubing.
• Magnetic susceptibilities and partial pressures of gases vary with temperature.
Permissible ambient temperature range is 32°F to 113°F (0°C to 45°C).
• The interior of the Detector Assembly is maintained at approximately 144°F (62°C) by
an electronically controlled heater. Prior to entering the detector assembly, the sample
is heated in a coiled tubing to match the detector's temperature.

2.4 GASES
INSTALLATION
2
2.4.1 R
Calibration Gases
Analyzer Module calibration requires the establishment of zero and span calibration points.
This requires a zero standard gas to set the zero point span gas to establish a calibration
point at or near the upper range limit.
An oxygen-free gas, typically nitrogen, is required for use as the zero standard gas.
Recommendations for span calibration gases, bases on various operating ranges, are
tabulated in Table 3-1. Air (20.93% oxygen) can be used as span gas regardless of the
ranges used for sampling, although very low ranges may lose accuracy.
Sample Gas
Sample gas should be non-flammable.
Temperature
Sample temperature at the inlet should be from 50°F to 150°F (10°C to 66°C). A maximum
entry temperature of 110°F (43°C) is recommended to prevent cooling of the sample and
possible internal condensation. Such condensation could damage some components of the
Analyzer Module. This recommendation can be ignored if a thoroughly dry sample is
examined.
EQUIREMENTS
Pressure
Sample exhaust pressure limits are -5 to 10 psig (-345 to 690 hPa-gauge). Normal
operation is in the positive range, between 0 and 10 psig (0 and 690 hPa-gauge). Negative
gauge pressures are not normally recommended, but may be used in certain special
applications.
To prevent over-pressurization, insert a pressure relief valve into the sample inlet line. A
check valve should also be placed in the outlet line if the Analyzer Module is connected to a
manifold associated with a flare or other apparatus that does not operate at atmospheric
pressure.
The outlet port is commonly vented to the atmosphere. Any change in barometric pressure
has a directly proportional effect on the indicated percent of oxygen, and should be
neutralized through manual or computer correction of data. Note the following example:
Range = 0% to 5% oxygen
Barometric pressure change after calibration = 1%
748419-B
June 2000
Paramagnetic Detector Analyzer Module
Rosemount Analytical NGA 2000

2
INSTALLATION
Analyzer Module measurement = 5% oxygen
Measurement error = 0.01 x 5% oxygen
Fullscale span = 5% oxygen
0.05% oxygen error = 1% of fullscale
The error is more significant for suppressed range 99% to 100%.
An optional barometric pressure compensation board is available to automatically perform
this correction.
A general rule regarding calibration gas pressure is that it should be the same as the
expected sample gas pressure during routine operation.
The above requirement increases the difficulty of operation at negative gauge pressure. A
suction pump can be connected to the outlet port for drawing sample through the Analyzer
Module. Such operation necessitates special precautions to ensure accurate readout,
including the following:
The need for equilibrium between sample and gas calibration pressures.
Any leakage in the sample handling system will decrease readout accuracy.
Flow Rate
Recommended sample flow rate is 800 to 1400 ml/min., ±40 ml/min. Optimum flow rate is
1100 ml/min.
If flow is held to within tolerance and operating pressure remains constant, zero and span
drift will meet specified limits.

3.6 STARTUP PROCEDURE
Introduce a suitable on-scale gas (NOT actual sample) into sample inlet.
Apply power to the PMD Analyzer Module. If it is associated with a Platform, do this by
plugging in the Platform to a power source. The Platform has no ON/OFF power switch.
Once power is supplied to the Platform, the PMD Analyzer Module will be energized.
If the user's system contains only one Analyzer Module, all system components, the
Controller Board and the network "self-install" (bind together) during initial startup. If the
system contains more than one Analyzer Module, the startup sequence will interrogate the
network to locate and identify all components on the network. The u ser will have to bind
appropriate combinations of components after the startup sequence.
After the warm-up period, approximately one hour for PMD Module, all modules are
completely functional.
Enter appropriate data in the Calibration Gas List (by making the following display
selections: Main Menu, Expert Controls and Setup [enter security code, if necessary],
Analyzer Module setup, Calibration Gas List). Also, enter appropriate values in the
Calibration Parameters menu (by making the following display selections: Main Menu,
Expert Controls and Setup [enter security code, if necessary], Analyzer Module Setup,
Calibration Parameters), particularly data related to which ranges are to be zeroed together
and how the Analyzer Module is expected to calibrate ranges (separately or otherwise).
The Analyzer Module will not allow the user to increase the upper limit of a range beyond
the "maximum range" software setting. To change the "maximum range" value, select the
748419-B

STARTUP AND OPERATION
following from the Main Menu: Technical Configuration Menu, Service Menu, Manufacturing
Data, Analyzer Module Data. Select Maximum Range, and use the arrow keys to scroll the
indicated value. The same applies for "minimum range" settings.
3.7 BINDING
To achieve full coordination between Analyzer Modules and associated I/O Modules, the
user must bind those components together in the System Setup portion of the Technical
Configuration Menu in software.
3.8 CALIBRATION
Calibration consists of establishing zero and span calibration points. Generally, zero and
span calibration should be performed on the range that will be used during sample analysis.
To calibrate the PMD Analyzer Module, introduce zero gas into the SAMPLE INLET, and do
the following:
1. If the Multi-Analyzer Module, split Run Mode display is shown, press the DISPLAY
softkey until the desired Analyzer's Run Mode display is acquired.
2. Press the MENUS softkey to enter the Main Menu.
3. Press the ENTER key to enter the Basic Controls menu.
4. Press the ZERO softkey to enter the Analyzer Zero menu.
5. Press the ZERO softkey and wait.
6. Introduce span gas (Table 3-2) into the SAMPLE INLET.
7. Press the SPAN softkey to enter the Analyzer Span menu, press SPAN again and wai t.
8. Press the HOME softkey to re-enter the Main Menu.
9. Press the DISPLAY softkey for the Run Mode display.

If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is initiated,
nothing happens), a possible solution relates to the use of an incorrect gas for zeroing or
spanning (e.g., using a high concentration gas to zero or a zero gas to span the Analyzer
Module). Recalibrating with the appropriate gas(es) WILL NOT correct the problem
because the ZERO OFFSET or SPAN FACTOR has been set to an extreme value in the
process.

STARTUP AND OPERATION
To remedy the problem, do the following:
1. Select the following from the Main Menu: Expert Controls and Setup (enter security
code if necessary), Analyzer Module Setup, and Calibration Parameters.
2. Using the down arrow, select Zero Ranges, press ENTER and, using the up/down
arrows, toggle to SEPARATE. Do the same for the Span Ranges selection. Do not
press ESCAPE at any time unless retention of prior settings is desired.
3. Return to the Main Menu (HOME) and make the following selections: Expert Controls
and Setup (enter security code if necessary), Expert Analyzer Controls, CAL softkey,
FACTORS softkey, and Range 1 (2, 3, 4) Factors. (Do steps 4 and 5 for each range.)
4. Select Zero Offset, press ENTER, adjust the value to 525000 with the up/down arrow
keys, and press ENTER. Do not press ESCAPE at any time unless retention of prior
settings is desired.
5. Select Span Factor, press ENTER, adjust the value to 0.000015 with the up/down arrow
keys, and press ENTER. Do not press ESCAPE unless retention of prior settings is
desired.
6. Attempt to recalibrate the Analyzer Module according to the procedure outlined at the
beginning of Section 3.8. If re-calibration fails, return to the Range Factors menu,
readjust factors, and attempt calibration again.
3.9 BACKGROUND GAS COMPENSATION
Any gas having a composition other than 100% oxygen contains background gas, that is,
non-oxygen components. Sometimes, the PMD Module response to background gas is
significant, depending largely on the span and range used.
If the operator uses zero and span gases that contain the same background gas as the
sample, calibration procedures automatically compensate. No adjustments are necessary.
If the background gas in the sample is different from that in the zero and/or span gases, the
operator must take into consideration background effects to ensure correct readout. During
entry of zero and span gas values in the Calibration Gas List, the instrument is not set to
indicate the true oxygen content of the zero and span standard gases. It is set to indicate a
slightly different value, relative to background gas, calculated to provide correct readout
during subsequent analysis of sample gas.

Oxygen Equivalent Values of Gases
Paramagnetic Detector Analyzer Module
Rosemount Analytical NGA 2000
748419-B
June 2000
STARTUP AND OPERATION
For computation of background corrections, the analyzer's response to each component of
the sample must be known. Table 3-4 lists the percentage oxygen equivalent values for
many common gases. For a more comprehensive list of oxygen equivalent values, refer to
a resource text such as the Handbook of Chemistry and Physics for tables of magnetic
susceptibility of substances. The percentage oxygen equivalent of a gas can be determined
by the following equation, assuming both gases are supplied at the same pressure:
Analyzer Response to Gas
% O2 Equivalent of Gas =
Analyzer Response to O
For example, if the analyzer's response to oxygen is +100%, the response to xenon would
be -1.34%.
The oxygen equivalent of a gas mixture is the sum of the contribution of the individual gas
components.
Example: Zero Based Range
X 100%
2
3
At lower range limit (i.e., 0% O2), composition of sample is: 80% CO2, 20% N2.
From Table 3-4, the percent oxygen equivalents are: CO2 -0.623%, N2 -0.358%.
The percent oxygen equivalent of the mixture =
0.8(-0.623) + 0.2(-0.358) = (-0.4984) + (-0.0716) = 0.570% O2.
Computing Adjusted Values for Calibration Gas List
Before calibrating the Analyzer Module, values in the Calibration Gas List must be adjusted
to correct for magnetic susceptibility of background gas. In the equation that follows, the
quantities are defined as follows:
• BGGst = oxygen equivalent of background gas in standard gas (Table 3-4).
• BGGs = oxygen equivalent of background gas in sample (Table 3-4).
• OP = operating pressure. Unless special pressure corrections are to be made,
the zero standard, span standard and sample gases must all be admitted at the
same pressure.
Use the following equation to compute the adjusted settings for the Calibration Gas List:
Adjusted percent oxygen for standard gas =
(A)[100 + (B-C)]-100[B-C]
100
Where:
748419-B
June 2000
A = true percent oxygen of standard gas
B = BGGs
C = BGGst

STARTUP AND OPERATION
Example:
Background gs in sample is CO2, oxygen equivalent = -0.623%.
Zero gas is 100% N
Span standard gas is air: 21% O2, 79% N
2.
2.
Background gas in zero and span standard gases is N2, oxygen equivalent = 0.358%.
With N2 zero standard gas flowing, zero gas value in the Calibration Gas List would be
0.265% O2 (as determined by the following):
0[100+(-0.623-(-0.358))] - 100{-0.623-(-0.358)]
100
= 0.265% O
2
With air flowing, span gas value in the Calibration Gas List would be 21.21% oxygen (as
determined by the following):
21(100 - 0.265) - 100 (-0.265)
100
= 21.209% O2 ≅ 21.21 O
2
In two limiting cases, the general equation is reduced to simpler forms.
1. If the span standard gas is 100% oxygen, the adjusted oxygen value is the same as the
true value (i.e., 100% O2).
2. If the zero standard is an oxygen-free zero gas, the adjusted value for setting the ZERO
Control = BGGst-BGGs. (If the oxygen-free zero gas is more diamagnetic than the
background gas in the sample, this difference is negative. The negative value may be
entered in the Calibration Gas List.)
22
Alternately, the user can avoid these compensation calculations by using zero and span
gases which have been specially prepared to contain the expected amounts of background
gas. Calibration of the analyzer module will then factor in background gas effects in the
same proportions as normal run mode measurement.

STARTUP AND OPERATION
3.10 BAROMETRIC PRESSURE COMPENSATION
Although normally calibrated for readout in percent oxygen, the PMD Analyzer Module
actually responds to oxygen partial pressure. The partial pressure of the oxygen
component in a gas mixture is proportional to the total pressure of the mixture. Thus
readout is affected by pressure variations.
For instance, assume that an instrument is calibrated for correct readout with a standard
gas containing 5% oxygen, admitted at the normal sea level atmospheric pressure of 14.7
psia (1013 hPa). If the operating pressure now drops to one-half of the original value (i.e.,
to 7.35 psia/506 hPa and the calibration controls are left at the previously established
settings, the display reading for the standard gas will drop to 2.5%.
It is therefore necessary to calibrate the in strument at the same pressure that will be used
during subsequent operation, and to maintain this pressure during operation.
Alternatively, an optional Barometric Pressure Compensation Board, typically used for
suppressed range applications, can perform signal corrections automatically.

ENERAL PRECAUTIONS FOR HANDLING AND
G
TORING HIGH PRESSURE GAS CYLINDERS
S
Edited from selected paragraphs of the Compressed
Gas Association's "Handbook of Compressed Gases"
published in 1981
Compressed Gas Association
1235 Jefferson Davis Highway
Arlington, Virginia 22202
Used by Permission
1. Never drop cylinders or permit them to strike each other violently.
2. Cylinders may be stored in the open, but in such cases, should be protected against
extremes of weather and, to prevent rusting, from the dampness of the ground. Cylinders
should be stored in the shade when located in areas where extreme temperatures are
prevalent.
3. The valve protection cap should be left on each cylinder until it has been secured
against a wall or bench, or placed in a cylinder stand, and is ready to be used.
4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be
moved by using a suitable hand-truck.
5. Never tamper with safety devices in valves or cylinders.
6. Do not store full and empty cylinders together. Serious suckback can occur when an
empty cylinder is attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 125°F (52°C). A
flame should never be permitted to come in contact with any part of a compressed gas
cylinder.
8. Do not place cylinders where they may become part of an electric circuit. When electric
arc welding, precautions must be taken to prevent striking an arc against the cylinder.
