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-RM Moisture Analyzer should not produce, or fall victim to,
electromagnetic 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 pre-
vent or minimize 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 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
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.

Overview
The 3050-RM Moisture Analyzer reliably measures moisture concentrations in a
variety of industrial and UHP gases, using a quartz crystal microbalance (QCM)
sensor. The calibrated range of the analyzer is 0–2500 PPMV. The QCM Sensor
used in this analyzer is compatible with Air, argon, butane, carbon dioxide,
ethane, ethene, Freon 12, Freon 22, Freon 32, Freon 114, Freon 116, Freon 125,
Freon 134A, Freon 152, helium, hydrogen, krypton, natural gas, neon, nitrogen,
oxygen, propane, propene, SF6, and xenon. Carbon dioxide is also compat-
ible, but requires an alternate Sensor assembly (refer to the 3050-RM Analyzer
Replacement Parts list in Chapter 4 for ordering part number). Please contact
the factory to conrm compatibility with other gases.

Moisture Sensor
Quartz Crystal Microbalance (QCM)
The 3050-RM Analyzer uses a quartz crystal microbalance sensor to measure
water vapor concentration. This is a piezoelectric device that is capable of
extremely sensitive mass measurement. To make the QCM sensitive to water
vapor the surface is coated with a thin lm of hygroscopic material. When gas
ows through the sensor, the coating absorbs or desorbs moisture, changing
the natural resonance frequency of the crystal.
Gas Measurement Cycle
The gas measurement cycle is divided into two (2) periods.
During the rst period of the cycle, dry Reference gas ows through the
Sensor assembly and the frequency is recorded.
During the second period of the cycle, Sample gas ows through the Sen-
sor and a second measurement of the Sensor frequency is recorded.
The dierence between these two (2) frequency measurements is known
as the delta frequency (∆ƒ). The ∆ƒ value is a function of the moisture con-
centration in the Sample gas.

Gas Flow
Sample System
The 3050-RM Moisture Analyzer sample system enables the analyzer to make reli-
able water vapor measurements at concentrations down to 0.1 PPMV. The sample
system serves several purposes:
• It controls the sample conditions at the Sensor assembly (e.g., ow rate,
temperature, pressure). Hence, the QCM-based Sensor is isolated from
variations in the ambient conditions that would otherwise alter the re-
sponse characteristics of the Sensor.
• The sample system is designed to continuously switch the Sensor assem-
bly between the Sample gas and a dry Reference gas. This sample switch-
ing scheme yields both higher sensitivity and reduced drift in the Sensor
readings.
Overview |1-5

PN 305892901, Rev S
Sample Flow
Normal operation of the 3050-RM Analyzer uses an internal bypass, which
increases the response speed of the system. However, the 3050-RM is capable
of running in a gas-saver mode as well, which allows the analyzer to run on a
sample volume of approximately 150 SCCM.
There are four separate sample paths in the 3050-RM Analyzer manifold.
 The rst is a simple bypass that allows for an increased ow rate of sample
gas. This means that when you open the bypass valve (SV1), you reduce
the time required to equilibrate all portions of the sample system that
exist upstream of the bypass valve. A capillary tube, located immediately
downstream of SV1 (the coil shape in Figure 1-2), limits the ow rate to ap-
proximately 1 standard liter per minute (the exact value of the bypass ow
is a function of the inlet pressure to the analyzer).
