2.1. Description of the System
The portable AMI INSPECTOR instrument is a complete monitoring
system mounted on a small panel with supporting stand and a rechargeable battery for stand-alone operation (>24h), designed as
an inspection equipment for quality assurance of online process
monitors.
Features General Features of AMI INSPECTORs are:
Battery life after full charge:
– >24h at full load (
use of 3 relays, USB, signal output, logger
)
– >36h at minimum load (use of logger only)
Charging time: approx. 6 hours
Controlled shut-down if battery is empty.
Display of remaining battery life in hours.
For longer battery life the back light of the LC Display is dis-
abled.
Continuous operation using power adapter. The battery
should be discharged at least once a month (normal usage
until the monitor automatically shuts down).
Battery The Li-Ion battery is located in the housing of the AMI transmitter.
See chapter Power Supply, p. 18 regarding power supply and
charging of the battery.
Safety features No data loss after power failure, all data is saved in non-volatile
memory. Over voltage protection of in- and outputs.
Galvanic separation of measuring inputs and signal outputs.
USB interface Built-in USB interface for logger download. Use the USB stick sup-
plied by Swan only (other USB sticks can dramatically reduce battery life).

Measuring
principle
Hydrogen is measured by an amperometric method. A small voltage, called polarization voltage, is applied between two electrodes.
If a hydrogen molecule hits the positively charged platinum electrode (anode) it will be oxidized. This means that two electrons are
removed under the influence of the positive voltage and the catalytic properties of the platinum. This leaves two (charged) protons and
two electrons behind.
(1) H2 ––> 2 H
+
+ 2 e
-
The two electrons are transported by the polarization voltage
source to the negatively charged silver-silver chloride electrode
(cathode), causing the following reaction:
(2) AgCl + 2 e
-
––> Ag + 2 Cl
-
Finally the two kinds of ions produced will combine into a small
amount of hydrochloric acid:
(3) 2 H+ + 2 Cl
-
––> 2 HCl
If the hydrogen concentration in the sample increases more hydrogen molecules will hit the platinum anode within a given time.
Therefore more electrons will be transported within a given time
which corresponds actually to an increased electrical current. This
current can be measured by the electronics. It is directly proportional to the concentration of hydrogen in the sample. Formula (2) indi-

cates that in the course of the hydrogen measurement the silver
chloride is reduced to elemental silver. If all silver chloride has been
converted to silver the hydrogen sensor has to be refurbished in the
factory. However there is enough silver chloride provided to keep
the sensor operational during two years under normal conditions.
The actual SWAN hydrogen-sensor design is based on the wellknown Clark principle. Clark-type oxygen sensors have been successfully in use for many years.

6.3. Maintenance of the Hydrogen Sensor
6.3.1 Hydrogen Sensor Handling
Never attempt to open the hydrogen sensor.
Always store the sensor in water or in the wet flow cell.
Always keep the sensor connected to the AMI INSPECTOR
Hydrogen.
Always keep the sensor polarized. Without polarization the
sensor suffers a loss of sensitivity.
The AMI INSPECTOR Hydrogen has a buffered polarization
source which will keep the hydrogen-sensor polarized for
some days, even if the AMI INSPECTOR Hydrogen is
switched off.
However, it is a good idea to keep the AMI running all the
time. The AMI INSPECTOR Hydrogen should be connected
to the power supply and switched on even if it is not in use.
During calibration do not expose the sensor to 100 % Hydro-
gen longer than 6 minutes. Otherwise the extremely dry gas
might dry out the capillary layer of electrolyte between platinum anode and plastic membrane, which makes the sensor
response unstable.
The hydrogen molecule is very small and migrates into al-
most any material including electrolyte, plastics and even
metals and will remain there for some time. After a calibration
it may take a few hours until the residual current of the sensor
has dropped enough to measure very low levels of hydrogen
again.
The hydrogen-sensor shows usually a small positive offset,
which means there is a small positive value in air (without hydrogen, normally below one ppb). This value can be set to
zero: <Installation > Sensors > Miscellaneous > Offset. Use
with care!

6.4. Quality Assurance of the Instrument
Every SWAN on-line instrument is equipped with integrated, autonomous quality assurance functions to survey the plausibility of each
measurement.
For the AMI Hydrogen these are:
continuous monitoring of sample flow
continuous monitoring of the temperature inside the transmit-
ter case
periodic accuracy test with ultra high precision resistors
Further a manual, menu driven inspection procedure can be carried
out using a certified reference instrument. Running at the same
sampling point as an inspection equipment, the AMI INSPECTOR
Hydrogen verifies the measuring results. After enabling the quality
assurance procedure by defining the quality assurance level, the
instrument reminds the user periodically to run the procedure and
results are stored in a history for review.
Quality
assurance
level
Central feature of the quality assurance function is the assignment
of the monitored process to a Quality assurance level.
There are three predefined levels plus a user level. Hereby the inspection interval, the deviation limits of temperature and measuring
result between the inspection equipment and the monitoring instrument are defined.
Level 1: Trend; Measurement used as an additional informa-
tion to follow the process indicating trends.
Level 2: Standard; Monitoring of several parameters of a pro-
cess (e.g. hydrogen, saturation). In case of instrument failure,
other parameters can be used for process monitoring.
Level 3: Crucial; Monitoring of critical processes, value is
used for control of another part or subsystem (valve, dosing
unit, etc.).
Additional level:
Quality level 4: User; User defined inspection interval, maxi-
mal deviation of temperature and measuring result.

6.4.2 Pre-test
Reference instrument: AMI INSPECTOR Hydrogen:
– Check certificate; reference instrument certificate not older
than one year.
– Check battery; Battery of the AMI INSPECTOR Hydrogen
should be completely charged. Remaining operating time
on display minimum 20 hours.
– Sensor is in working condition
On-line instrument: Monitor AMI Hydrogen:
– Good order and condition; Flow cell free of particles,
Sensor surface free of deposits.
– Check message list; Review the message list in menu 1.3
and check for frequently alarms (as for example flow
alarms). If alarms occur frequently remove cause before
starting the procedure.
6.4.3 Connect the sample lines
See corresponding chapter in the manual of the process monitor
which shall be checked with a reference instrument.
The choice of sampling depends strongly on local conditions on
site. Possible sampling:
via sample point,
via T-fitting or
via piggyback/ downstream
NOTICE:
• avoid ingress of air, use screwed fitting,
• sample as near as possible to the process monitor,
• wait approx. 10 minutes, whilst measurement is running, until
measurement value and temperature are stabilized.
Example As an example following picture shows the connection of the refer-
ence instrument via T-fitting to the process monitor.

As control
output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
Ziegler-Nichols method for the optimization of a PID controller:
Parameters: Setpoint, P-Band, Reset time, Derivative time
The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and
programming details. Choose control upwards or downwards.

5.2.1.43.5 Control timeout: If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value
does not come closer to the setpoint, the dosing process will be
