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-AMS 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.

PN 305804902, Rev A
Overview
The 3050-AMS Moisture Analyzer reliably measures low concentrations of
moisture in high purity gases at concentrations down to 0.035 parts-per-
million by volume (PPMV), using a quartz crystal microbalance (QCM) Sensor.
The calibrated range of the 3050-AMS is 0–100 PPMV with a trend indication
for measured concentrations to 1000 PPMV. The QCM-Sensor technology used
in this analyzer is compatible with inert gases, air, oxygen, nitrogen, hydrogen,
many Freons (12, 114, 116, etc.), and some specialty gases (e.g., sulfur hexa-
uoride). Carbon dioxide requires a custom Sensor assembly. Contact AMETEK
Service to conrm compatibility with other gases.

analyzer. These include:
 One (1) fully congurable analog output (4–20 mA) that can be self-pow-
ered or externally powered.
 Three (3) alarm contacts (data valid, concentration alarm, and system
alarm).
 One (1) RS-232 or one (1) RS-485 serial interface provides communication
between the analyzer and your recording or data acquisition equipment.
The 3050-AMS Analyzer is congured, and analyzer parameters are set, by us-
ing either the analyzer display, keypad and function keys, or using an external
PC.

Overview |1-3

PN 305804902, Rev A
Moisture Sensor
Quartz Crystal Microbalance (QCM)
The 3050-AMS Analyzer uses a QCM Sensor to measure water vapor concentra-
tion. 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 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 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-AMS Moisture Analyzer sample system enables the analyzer to make
reliable water vapor measurements at concentrations down to 0.035 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.
• The sample system’s design provides a means of challenging the analyzer
with a known source of dry gas to validate the baseline readings and to
compensate for any minor changes in background osets. As such, the
3050-AMS is designed to deliver reliable, long-term performance from the
QCM-based Sensor.
Overview |1-5

PN 305804902, Rev A
Sample Flow
In the normal operation of the 3050-AMS Analyzer, the Zero module (the sec-
tion enclosed in the dotted line in Figure 1-2) is turned o so that the Sample
gas enters the analyzer and passes through diaphragm valve 2 (DV2). After
exiting DV2, the ow splits into two (2) paths: the Sample gas path and the
Reference gas path. The sample path ows through the rst proportional valve
(PSV1) and the reference path ows through a dryer and PSV2. The two (2)
proportional valves (PSV1 and PSV2) control the ow rate of the gas streams.
They also determine which gas stream (Sample or Reference) passes through
to the QCM Sensor. By measuring the pressure drop across the capillary tube,
the 3050-AMS Analyzer provides a feedback signal (the ow rate of the Sample
gas) to the proportional valves. As a result, the 3050-AMS Analyzer alternately
exposes the QCM Sensor to a controlled ow of the Sample and dry Reference
gases.
