2. Product Description
This manual describes the functions of the following monitors
AMI Oxytrace
AMI Oxytrace QED
Both monitors are mainly identical except that AMI Oxytrace QED
includes a faraday verification.
2.1. Description of the System
Application AMI Oxytrace is used to measure low levels of oxygen in high-puri-
ty water. Especially in power plant water cycles (e.g. feedwater), a
very low level of oxygen is needed to prevent corrosion.
Measuring
principle
Clark principle:
The sensor consists of one noble metal electrode (e.g. platinum or
gold), a reference electrode (mostly Ag/AgCl) and optionally a metal guard electrode.
The Clark-type electrode is the most widely used oxygen sensor for
measuring oxygen dissolved in a liquid. The basic principle is that
there is a cathode and an anode submersed in an electrolyte and a
voltage is applied between the two parts. Oxygen enters the sensor
through a permeable membrane by diffusion, and is reduced at the
cathode according to
O
+ 4e- + 2 H2O --> 4 OH
2
This reaction creates a measurable current. There is a linear correlation between the oxygen concentration and the electrical current.
The guard electrode is on the same voltage level as the cathode
but there is no current measurement. Oxygen which diffuses from
the electrolyte to the cathode is consumed by the guard electrode.
As a consequence, residual oxygen in the electrolyte will no more
disturb the measurement signal and the response time to low oxygen levels will be shorter.
-
Temperature
compensa-
tion
The measuring signal depends on temperature, but is automatically
compensated to 25 °C. The sample temperature is determined continuously by a temperature sensor inside the oxygen electrode.

For AMI Oxytrace QED only.
When a direct current is passed through water by means of two
electrodes, electrolysis of the liquid takes place, according to the
laws of Michael Faraday. Water is converted to molecular oxygen
and hydrogen.
Thus, by controlling the current, a fixed, known amount of oxygen,
which is independent of temperature and pressure, may be generated. If the sample flow is known, an exact oxygen concentration
increment can be generated at low levels. This increment is used to
verify the flawless operation of the whole system. Thereby the response characteristics (incremental change and response time) of
the sensor are taken into account. Sensor failures (loss of electrolyte etc.) can be detected very easily as shown in the plot below.

Time [Sec]
Unusual sensor performance is recognized immediately and gives
also a maintenance indication to the operator/user. The faraday
verification is therefore an excellent QA/QC tool.

Connect the power cord, do not switch on power until all external
devices are connected.
The Swansensor Oxytrace G is delivered with prefilled electrolyte
chamber. A transport protection cap filled with water keeps the
sensor wet during transport and storage. Before installation,
remove the transport protection cap and clean the sensor surfaces with water. Afterwards install the oxygen sensor and connect the cable.

First, the analyzer performs a self test, displays the firmware version and then starts normal operation
Leave the sensor at the air. The sensor has to run-in for at least
30 min, better 1 h. During this time it has to be at air with a dry and
clean membrane and has to be connected to the powered instrumenty. Calibrate the sensor after this time, see Calibration, p. 47.

3.2. Mounting of Instrument Panel
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation
material is available:
– 4 Screws 8x60 mm
– 4 Dowels
– 4 Washers 8.4/24 mm
Mounting re-
quirements
The instrument is only intended for indoor installation.

3.3. Connecting Sample Inlet and Outlet
3.3.1 Swagelok Fitting Stainless Steel at Sample Inlet
Preparation Cut the tube to length and deburr it. The tube must be straight and
free from blemishes for approximately 1,5 x tube diameter from the
end.
Lubrication with lubricating oil, MoS2, Teflon etc. is recommended
for the assembly and reassembly of bigger sized unions (thread,
compression cone).
Installation 1 Insert the compression ferrule [C] and the compression
cone [D] into the union nut [B].
2 Screw on the union nut onto the body, do not tighten it.
3 Push the stainless steel pipe through the union nut as far as it
reaches the stop of the body.
4 Mark the union nut at 6 o’clock position.
5 While holding the fitting body steady, tighten the nut union 1¼
rotation using an open ended spanner.

WARNING
Risk of electrical shock.
Do not perform any work on electrical components if the transmitter is switched on. Failure to follow safety instructions could
result in serious injury or death.
Always turn off AC power before manipulating electric parts.
Grounding requirements: Only operate the instrument from
an power outlet which has a ground connection.
Make sure the power specification of the instrument corre-
sponds to the power on site.

WARNING
External Voltage.
External supplied devices connected to relay 1 or 2 or to the
alarm relay can cause electrical shocks
Make sure that the devices connected to the following con-
tacts are disconnected from the power before resuming in-
stallation.
–relay 1
–relay 2
– alarm relay
WARNING
To prevent from electrical shock, do not connect the instrument
to the power unless the ground wire (PE) is connected.
Do not connect unless specifically instructed to do so.
WARNING
The mains of the AMI Transmitter must be secured by a main
switch and appropriate fuse or circuit breaker.
