module before operating it. Read this instruction manual completely.
To avoid explosion, loss of life, personal injury and damage to this equipment
and on-site property, all personnel authorized to install, operate and service the
this equipment should be thoroughly familiar with and strictly follow the
instructions in this manual. SAVE THESE INSTRUCTIONS.
If this equipment is used in a manner not specified in these instructions, protective
systems may be impaired.
DANGER is used to indicate the presence of a hazard which will cause severe
personal injury, death, or substantial property damage if the warning is ignored
WARNING is used to indicate the presence of a hazard which can cause severe
personal injury, death, or substantial property damage if the warning is ignored.
CAUTION is used to indicate the presence of a hazard which will or can cause minor
personal injury or property damage if the warning is ignored.
NOTE is used to indicate installation, operation, or maintenance information which is
important but not hazard-related.

WARNING: POSSIBLE EXPLOSION HAZARD
This equipment is not designed for and should not be used in the analysis of
flammable samples. Use of this equipment in this way could result in explosion
and death.
Note
Apply leak test liquid to cell or detectors only as a last resort.
WARNING: POSSIBLE EXPLOSION HAZARD
Verify that all gas connections are made as labeled and are leak free. Improper
gas connections could result in explosion or death. See Section 2.4.3 for Leak
test procedure.
WARNING: PARTS INTEGRITY
Tampering or unauthorized substitution of components may adversely affect
safety of this product. Use only factory documented components for repair
WARNING: OVER-VOLTAGE SPIKING
If this Analyzer Module is used with a non-Rosemount Analytical power supply,
adding Rosemount Analytical PN 90331 Current Protector in series with the 24 V
positive line will prevent over-voltage spiking and resultant fuse blowing when
powering up the instrument.
CAUTION: PRESSURIZED GAS
This module requires periodic calibration with a known standard gas. See
General Precautions for Handling and Storing High Pressure Gas Cylinders in
the rear of this manual.

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.
