Electromagnetic Compatibility (EMC)
Read and follow the recommendations in this section to avoid performance
variations or damage to the internal circuits of this equipment when installed
in harsh electrical environments.
The various congurations of the 3050-DO 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 that certain installation techniques and wiring practices are used to prevent or mini-
mize erratic behavior of the Analyzer or its electronic neighbors. 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 pow-
er. Foil and braid shielded I/O and DC power cables are recommended for use in otherwise unprotect-
ed 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 shielding 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 protec-
tion depending on the electronic environment. Connecting one shield ground via a 0.1 microfarad ce-
ramic capacitor is a technique allowing high frequency shield bonding while avoiding 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 grounded 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 so that the shield materials can be wrapped
backwards onto the cable jacket and captured inside the gland, and tightened up against the metal
interior.
Inductive loads connected to the low voltage“Alarm Contacts”are not recommended. However, if
this becomes a necessity, adhere to proper techniques and wiring practices. Install an appropriate
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 using 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 where 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.

xii | 3050-DO Moisture Analyzer

PN 305725901, Rev YF
Overview
The 3050 Moisture Analyzer is a smart sensor that measures trace concentra-
tions of moisture in a process gas stream. At the heart of the 3050-DO Analyzer
is a 3050-OLV, which has been modied for operation at moisture concentra-
tions below 100 PPBV. The 3050-DO Analyzer 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 1-4 for a Gas List. The analyzer is calibrated to
measure moisture content from 1–2500 PPMV. Data output can be in units of
PPMV, PPMW, lb/mmscf, and mg/Nm3.
The heart of the 3050-DO Analyzer is a quartz crystal microbalance (QCM) Sen-
sor that is sensitive to moisture. The QCM Moisture Sensor is simply a quartz
crystal oscillator, in which the quartz crystal has been coated with a propri-
etary hygroscopic 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, changing the mass of the coating. Changes in the mass are detect-
ed as changes in the natural resonance frequency of the oscillator.
In the analyzer’s Normal operating mode, the QCM Sensor is alternately
exposed 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 0.010 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
smart Sensor. Communication with the smart Sensor 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.
• Three alarm contacts (dry relay contacts).
• One RS-232 serial port.
• One RS-485 serial port.
The 3050-DO Analyzer has no local user programming functions. It requires se-
rial 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 95/NT format. User provided software may also be used
with the 3050 serial ports.
Verication
The 3050-DO Analyzer has a built-in Moisture Generator for onboard Verica-
tion. 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 initiat-
ed, 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 performed on a sample of the process gas. This yields the most
realistic test of the sensors performance under process conditions.
Overview | 1-3

PN 305725901, Rev YF
Gas Flow
Normal operation of the 3050-DO Analyzer includes an internal bypass, which
increases the response speed of the system; however, the 3050-DO Analyzer is
capable of running in a Gas Saver mode which allows the analyzer to run on a
sample volume of 150 SCCM.
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
response time. The analyzer updates every 2.5 minutes instead of 1 minute;
however, the analyzer still responds within specications. Refer to analyzer
specications in Chapter 5.
