SAFETY SUMMARY

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 Model 340
Trace Moisture Analyzer should be thoroughly familiar with and strictly follow the
instructions in this manual. Save these instructions.

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: ELECTRICAL SHOCK HAZARD

Do not operate without doors and covers secure. Servicing requires access to
live parts which can cause death or serious injury. Refer servicing to qualified
personnel.

For safety and proper performance this instrument must be connected to a
properly grounded three-wire source of power.

Alarm switching relay contacts wired to a separate power source must be
disconnected before servicing.

WARNING: POSSIBLE EXPLOSION HAZARD

This analyzer is of a type capable of analysis of sample gases which may be
flammable. If used for analysis of such gases, the detection section of the
analyzer must be either in an explosion proof enclosure suitable for the hazard
classification of the gas, or protected by a continuous dilution purge system in
accordance with Standard ANSI/NFPA-496-1986 (Chapter 8) or IEC Publication
79-2-1983 (Section Three).

If explosive gases are introduced into this analyzer, the sample containment
system must be carefully leak checked upon installation and before initial
startup, during routine maintenance and any time the integrity of the sample
containment system is broken, to ensure that the system is in leak proof
condition. Leak check instructions are provided in Section 4.2.

Internal leaks resulting from failure to observe these precautions could result in
an explosion, causing death, personal injury or property damage.

WARNING: HIGH PRESSURE GAS CYLINDERS

Fuel, air and calibration gas cylinders are under pressure. Mishandling of gas
cylinders could result in death, injury or property damage. See General
Precautions for Handling and Storing High Pressure Cylinders, in the rear of this
manual.

CAUTION: PARTS INTEGRITY

Tampering or unauthorized substitution of components may adversely affect
safety of this product. Use only factory documented components for repair.

NTRODUCTION

1

The Model 340 Trace Moisture Analyzer automatically and continuously measures water
vapor concentrations, up to a maximum of 1000 ppm, in a gaseous sample stream. The
determination is based on the simultaneous absorption and electrolysis of water. The
instrument has a wide range of applications, in monitoring many gases used in
manufacturing processes. (Suitable and unsuitable sample gases are listed in Section 1.2.)

Permissible sample pressure range for the standard instrument is 10 to 100 psig. Optional
sampling accessories permit monitoring gas streams at atmospheric or sub-atmospheric
pressures.

The analyzer provides direct readout on a front panel meter and a selectable output for an
accessory potentiometric recorder. With all AC operated versions of the analyzer, a
selectable output for a current type recorder is obtainable through use of an optional plug in
the circuit board.

1.1 INSTRUMENT CONFIGURATIONS

The Model 340 Analyzer is made in the following configurations:

1. Panel Mounted Analyzer, Figure 1-1, with detector, electronic circuitry, and operating
controls housed in a single purgeable case. Available with internal flow system of either
stainless steel (193000 Analyzer) or brass (193001 Analyzer).

2. The 193004 Explosion Proof Analyzer, Figure 1-2. Designed for use in the chemical,
petrochemical, and petroleum industries, in applications where the sample stream
contains flammable gases, or where explosive vapors may be present at the installation
site. Control section is similar to that of the Panel Mounted Analyzer. Detector section is
contained in an explosion proof housing that meets the requirements for installation
under hazardous conditions specified as Class 1, Group D, Division 1, in the National
Electrical Code. Flow system is of stainless steel.

3. Portable Analyzer, Figure 1 -3. Available for operation on either 115 VAC, 50/60 Hz
(193005 Analyzer) or ±15 VDC from a self contained battery pack (193006 Analyzer).

Except where specifically stated otherwise, information in this manual applies to all versions
of the instrument.

1.2 SAMPLE GASES

WARNING: POSSIBLE EXPLOSION HAZARD

This analyzer is of the type capable of analysis of sample gases which may be
flammable. If used for analysis of such gases, the detection section of the analyzer
must be either in an explosion proof enclosure suitable for the hazardous
classification of the gas , or, protected by a continuous dilution purge system in
accordance with Standard ANSI /N FPA-496 -1986 (Chapter 8) or IEC Publication
79-2-1983 (Section Three).

If explosive gases are introduced into this analyzer, the sample containment system
must be carefully leak checked upon installation and before initial startup, during
routine maintenance and any time the integrity of the sample containment system is
broken, to ensure that the system is in leak proof condition. Leak check instructions
are provided in Section 4.2.

Internal leaks resulting from failure to observe these precautions could result in an
explosion causing death, personal injury or property damage.

Determination of whether a sample stream of a particular composition is suitable for
monitoring depends on its compatibility with the construction materials in a) the detector
cell, and b) the instrument flow system. In all instruments, the detector cell utilizes a thin film
of phosphorous pentoxide (P2O6) on rhodium electrodes. Depending on the intended

081854-P Rosemount Analytical January 2001

NTRODUCTION

application of a given instrument version, its internal flow system is constructed of either
stainless steel (for corrosion resistance) or brass (for non-corrosive sample gases only).

1.2.1 S

UITABLE SAMPLE GASES

Elemental Gases

Argon, Helium, Neon, Nitrogen, Oxygen, Hydrogen.

Inorganic Gaseous Mixtures and Compounds

Air, Carbon Dioxide, Carbon Monoxide, Sulphur Dioxide, Sulphur Hexafluoride.

Organic Gaseous Compounds

Butane, Ethane, Freon 12 , Methane, Propane, Halogenated Hydrocarbons.

1.2.2 U

NSUITABLE SAMPLE GASES

Gases that react with P206 to produce additional water

Example: alcohols, HF.

Gases that react with construction materials of the instrument
Gases that react with P2O6 to alter required absorption characteristics of the P2O

film

6

Examples: ammonia, amines.

Gases that polymerize to form a solid or liquid phase (they gradually desensitize the
detector cell by coating or clogging)

Example: Unsaturated hydrocarbons - alkynes, alkadienes and alkenes.

Gases that contain particulate solid or liquid materials such as dust and dirt found in
furnace atmosphere gases.

These must be avoided or filtered out upstream; oil mist or dust from some types of dryers
can clog the detector cell or desensitize the P2O6 film by forming a layer over the film.

Detector Section: Criteria for installation site are proximity to sample point, protection from
environment, and accessibility for servicing. Protect the unit adequately against shock and
extreme vibration.

Control Section: Principal criteria for the installation site is that it must be outside the
hazardous area. Hazardous locations are defined in Article 500 of the National Electrical
Code. An additional consideration is convenience in taking readings and servicing the unit.
