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 standalone 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
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, nitrogenfilled, hollow gas test body is suspended on a platinum/nickel alloy ribbon in a nonuniform 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.
748330-E Rosemount Analytical June 2000
NGA 2000 Paramagnetic Detector
1-1
NTRODUCTION
I
Measurement is accomplished by a
null-balance system, whereby the
displacement torque is opposed by an
equal and opposite restorative torque.
T he 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 samp le 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.

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 Analyz er Modul e are operati onal.
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 Analyz er Modul e halfway into pl ace.
CAUTION: 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.

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
2.4.1 R
EQUIREMENTS
ALIBRATION GASES
C
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.
2-2
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 should be non-flammable.
EMPERATURE
T
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.
RESSURE
P
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%
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.
LOW RATE
F
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.

(See Figure 2-3) Connect inlet and outlet lines for sample gas to appropriately labeled
fittings on the rear panel. Both connections are 1/4 inch ferrule-type compression
fittings.
Zero and span gases use the same inlet and outlet as the sample. Figure 2-4 shows
a typical external sample handling manifold for gas selection. Particulates must be
filtered down to two microns, gases generally require pressurization, and flow
measurement metering MUST be present.
2.4.3 L
EAK TEST
The Analyzer Module is thoroughly tested at the factory for gas leakage. The user is
responsible for testing for leakage only at the inlet and outlet fittings on the rear panel.
The user is also responsible for internal leak testing periodically and if any internal
pneumatic components are adjusted or replaced (with a test procedure selected by
the user).

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
user 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 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. See Figure 3-10 of this manual and
Section 1.5 of the I/O Modules Manual for binding instructions.
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.

ALIBRATION RANGE FOR VARIOUS SUPPRESSED RANGE OPERATIONS
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.
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.

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.
XYGEN EQUIVALENT VALUES OF GASES
O
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 ma gnetic 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:
% O2 Equivalent of Gas =
Analyzer Response to Gas
Analyzer Response to O
2
X 100%
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
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.
OMPUTING ADJUSTED VALUES FOR CALIBRATION GAS LIST
C
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
3-8
June 2000 Rosemount Analytical 748330-ENGA 2000 Paramagnetic Detector
TARTUP AND OPERATION
S
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:
A = true percent oxygen of standard gas
B = BGGs
C = BGGst
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.)
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
748330-E Rosemount Analytical June 2000

background gas. Calibration of the analyzer module will then factor in background gas
effects in the same proportions as normal run mode measurement.

XYGEN EQUIVALENTS OF COMMON GASES
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 instrument at the same pressure th at will be
used during subsequent operation, and to maintain this pressure during operation.
