Electromagnetic Compatibility (EMC)
Read and follow the recommendations in this section in order to avoid perfor-
mance variations or damage to the internal circuits of this equipment when
installed in harsh electrical environments.
The various congurations of the 3050-OLV Analyzer should not produce, or fall victim to, electromag-
netic disturbances as specied in the European Union’s EMC Directive. Strict compliance to the EMC
Directive requires certain installation techniques and wiring practices be used in order that erratic
behavior of the Analyzer, or its electronic neighbors be prevented or minimized. Below are examples
of the techniques and wiring practices to be followed:
In meeting the EMC requirements , the various Analyzer congurations described in this manual
rely heavily on the use of metallic shielded cables used to connect to the customer’s equipment
and power. Foil and braid shielded I/O and DC power cables are recommended for use in otherwise
unprotected situations. In addition, hard conduit, exible conduit, and armor around non-shielded
wiring also provides excellent control of radio frequency disturbances. However, use of these shield-
ing techniques is eective only when the shielding element is connected to the equipment chassis/
earth ground at both ends of the cable run. This may cause ground loop problems in some cases.
These should be treated on a case-by-case basis. Disconnecting one shield ground may not provide
sucient protection depending on the electronic environment. Connecting one shield ground via a
0.1 microfarad ceramic capacitor is a technique allowing high frequency shield bonding while avoid-
ing the AC ground, metal connection. In the case of shielded cables, the drain wire or braid connection
must be kept short. A two inch connection distance between the shield’s end, and the nearest ground-
ed chassis point, ground bar or terminal is highly recommended. An even greater degree of shield
performance can be achieved by using metallic glands for shielded cable entry into metal enclosures.
Expose enough of the braid/foil/drain where it passes through the gland such that the shield materials
can be wrapped backwards onto the cable jacket and captured inside the gland, tightened up against
the metal interior.
Inductive loads connected to the low voltage“Alarm Contacts”is not recommended. However, if this
becomes a necessity, proper techniques and wiring practices must be adhered to. Install an appropri-
ate transient voltage suppression device (low voltage MOV,“Transzorb”, or R/C) as close as possible to
the inductive device to reduce the generation of transients. Do not run this type of signal wiring along
with other I/O or DC in the same shielded cable. Inductive load wiring must be separated from other
circuits in conduit by the use of an additional cable shield on the oending cable.
In general, for optimum protection against high frequency transients and other disturbances, do not
allow installation of this Analyzer whereby its unshielded I/O and DC circuits are physically mixed with
AC mains, or any other circuit that could induce transients into the Analyzer or the overall system.
Examples of electrical events and devices known for the generation of harmful electromagnetic dis-
turbances include motors, capacitor bank switching, storm related transients, RF welding equipment,
static, and walkie-talkies.

PN 305200901, Rev YT
Overview
The 3050-OLV Moisture Analyzer measures trace concentrations of moisture in
a process gas stream. The 3050-OLV is compatible with He, Ar, Ne, Xe, Kr, O2, H2,
N2, NO, CO, CO2, light hydrocarbons, natural gas, refrigerants, air, and specialty
gases. Refer to Figure 1-3 for a Gas List. The analyzer is calibrated to measure
moisture contents from 0.1–2,500 PPMV. Data output can be in units of PPMV,
PPMW, dewpoint Centigrade, dewpoint Fahrenheit, (required process pressure
input) lb/mmscf, and mg/Nm3.
The heart of the 3050-OLV is a quartz crystal microbalance (QCM) sensor that is
sensitive to moisture. The QCM moisture sensor is simply a quartz crystal oscil-
lator, in which the quartz crystal has been coated with a proprietary hygro-
scopic coating. This coating selectively, and reversibly, absorbs moisture from a
Sample gas stream. As the crystal is exposed to a gas stream containing water
vapor, the hygroscopic coating absorbs moisture from the gas stream, chang-
ing the mass of the coating. Changes in the mass are detected as changes in
the natural resonance frequency of the oscillator.
In the analyzer’s normal operating mode, the QCM sensor is alternately ex-
posed to the Sample gas and a dry Reference gas. A dry Reference gas is
produced by passing a portion of the Sample gas through a Dryer to remove
any moisture present (i.e., the moisture content of the dry Reference is less
than 0.025 PPMV). The dierence in the resonant frequency of the QCM sensor,
as measured when exposed to each of the two gas streams, is a function of the
moisture content of the Sample gas. Thus, the moisture concentration of the
Sample gas is determined from this frequency dierence. The calibration data,
which relates the moisture concentration of the gas stream to the measured
frequency dierence, are stored in an EEPROM within the QCM sensor module.

Controller Communication
All analyzer functions are controlled by a microprocessor housed within the
analyzer. Communication with the analyzer is achieved through the following
connections:
• One analog input, 4–20 mA.
• One analog output, 4–20 mA, isolated. Can be either loop powered or
powered by the analyzer.
• Two alarm contacts (dry relay contacts).
• One RS-232 serial port.
• One RS-485 serial port.
The 3050-OLV has no local user programming functions. It requires serial
communication with an external PC for conguration. Once congured, the
analyzer is capable of standalone operation. The analyzer is factory congured
and packaged with Congurator Software for initial setup of operating param-
eters. For enhanced interface and process monitoring, AMETEK oers optional
System 2000 Software with graphical user interface to record and process your
data in a Windows environment. User provided software may also be used with
the 3050-OLV serial ports.
Overview | 1-3

PN 305200901, Rev YT
Verication
The 3050-OLV has a built-in Moisture Generator for onboard Verication. A
portion of the dry Reference gas ows through the Moisture Generator where
a known amount of moisture is added. When Cell Verication is initiated, the
QCM sensor is alternately exposed to gas from the Moisture Generator and dry
Reference gas. The moisture value is compared to a stored value. The sensor
can make an adjustment if the value is within a tolerance band. If the value is
outside the tolerance band, an alarm will activate.
Since the Moisture Generator uses a dried portion of Sample gas, sensor
Verication is preformed on a sample of the process gas. This yields the most
realistic test of the sensors performance under process conditions.
Gas Flow
The 3050-OLV Moisture Analyzer requires 150, ±20 SCCM sample volume to
operate. The ow is split between Sample, Reference, and Moisture Generator
sections of the sample system. The ow through the sample cell is maintained
at 50 SCCM with the remaining gas vented to exhaust. There is a bypass valve
in the analyzer that vents the inlet to exhaust through a ow restrictor. Activa-
tion of the bypass will increase total ow by approximately 1 SLPM. Note that
the bypass valve will improve system response time.
Internal Timing
The analyzer operates in two timing modes. The Normal mode consists of
short intervals of Sample and Reference gas. The Sensor Saver mode reduces
the exposure of the sensor to the Sample gas by increasing the time spent on
the dry Reference.
If the analyzer detects abnormal degradation of sensor performance over time
in the Normal mode, the analyzer will automatically switch to Sensor Saver
mode. Once the analyzer switches to Sensor Saver mode, it will not switch
back on its own.
The Sensor Saver mode extends the life of the sensor, but provides slower re-
sponse time. The analyzer updates every 2.5 minutes instead of one (1) minute.

PN 305200901, Rev YT
Dewpoint Conversions
The 3050-OLV Analyzer is capable of outputting the moisture concentration in
units of dewpoint (Centigrade or Fahrenheit). Dewpoint values are calculated
from the moisture concentration measurements (PPMV) and the sample (i.e.,
process) pressure. For temperatures below 0 °C the 3050-OLV uses equations
to determine the water vapor pressure over ice, rather than over super-cooled
water. Thus, the 3050-OLV reports a “frostpoint” temperature, which is consis-
tent with the physical form of the condensed phase in a real process stream.
Water in super-cooled liquid state will only exist as a transient species, as the
rst bit of condensate starts to form on a smooth-chilled surface (i.e., the true
method of measuring a “dew”point). Given more time, the“dew” layer will turn
to ice, if the temperature is below the freezing point. While the“frostpoint”
temperature will be higher than the“dewpoint” temperature, the exact mag-
nitude of the dierence will be a function of both the pressure and dewpoint/
frostpoint temperature.
A second consideration, when using the 3050-OLV Analyzer to calculate
dewpoint/frostpoint temperatures, is the sample (i.e., the process) pressure.
The range of process pressures allowed by the 3050-OLV is restricted for many
sample gases. Many gases liquefy at relatively low pressures, so calculating a
dewpoint/frostpoint temperature for these compounds has no value. There-
fore, the 3050-OLV is designed to report an error condition (i.e., process-pres-
sure alarm), to alert the user of conditions that result in ambiguous dewpoint/
frostpoint values.
Denition of Natural Gas
The composition of natural gas streams varies greatly from application to
application. Normally, the methane content of these gas streams is approxi-
mately 90 %, and the concentration of the heavier hydrocarbons falls o with
increasing molecular weight. Because the 3050-OLV Analyzer uses a thermal
mass ow meter as part of its ow control system, it is necessary to dene
the composition of the gas stream to calculate the appropriate Flow Control
parameters. A methane content of 80–90 % has been used to dene the Flow
Control parameters for the“natural gas”listed in the 3050-OLV Analyzer Gas
List (Figure 1-3). If the methane content is above 95 %, AMETEK recommends
selecting methane from the Gas List. In the event that the methane content is
below 80 %, please contact AMETEK for instructions on selecting the appropri-
ate gas from the listing.

Calculation of Dewpoint Values for Hydrocarbon
Streams
The calculation of dewpoint values for hydrocarbon streams is covered by
several standards. Because there are dierences between the dewpoint values
calculated with the older North American standard (ASTM D1142, which is
based on the work published in IGT Research Bulletin #8) and the new Europe-
an standard (ISO 18453, which is based on the work presented in GERG-Water
Correlation: GERG Technical Monograph TM14, 2001), AMETEK has provided a
means of using either method in the 3050-OLV product. Specically, in the Gas
List we have cited two separate entries for natural gas. The rst entry is labeled
“Natural Gas”, and will provide dewpoint/frostpoint values consistent with
ASTM D1142. The second entry is labeled “Natural Gas GERG”, and will provide
dewpoint/frostpoint values consistent with ISO 18453. All other aspects of ana-
lyzer performance are identical for both of the two natural gas listings.
