Product Description

This chapter contains technical data, requirements and performance data.

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 disabled.

 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. 19 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 supplied by Swan only (other USB sticks can dramatically reduce battery life).

Signal Output

(optional)

One signal output programmable for measured values (freely scaleable, linear or bilinear) or as continuous control output (control parameters programmable).

Product Description

Relay Two potential-free contacts programmable as limit switches for measuring values, controllers or timer for system cleaning with automatic hold function.

Maximum load: 100 mA/50 VAC

Alarm Relay One potential free contact.

Alternatively:

 Open during normal operation, closed on error and loss of power.

 Closed during normal operation, open on error and loss of power.

Summary alarm indication for programmable alarm values and instrument faults.

Input For potential-free contact to freeze the measuring value or to interrupt control in automated installations (hold function or remote-off)

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

-

+ 2 H

-

O

2

+ 4e

This reaction creates a measurable current. There is a linear correlation between the oxygen concentration and the electrical current.

2

O --> 4 OH

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 compensation

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.

Maintenance

Maintenance frequency depends strongly on the water quality. The

AMI INSPECTOR Oxygen is designed for determination of low level of dissolved oxygen in high purity water.

It is not suitable for the measurement of dissolved oxygen in waste water.

6.1.

Maintenance Table

Monthly

Half-yearly

Yearly

If necessary, perform an air calibration.

Clean Swansensor Oxytrace G membrane with a soft tissue.

If necessary, replace filling electrolyte.

If the sensor is exposed to air frequently during long time intervals, the electrolyte and membrane may have to be changed earlier (see below*).

Clean flow cell and flow meter, if dirty.

Replace Swansensor Oxytrace G membrane by using a new, prefilled sensor cap.

Every 2nd year

*A change of membrane and electrolyte is recommended:

 if indicated in the maintenance list (remaining amount

<10%)

 if the response of the sensor is slow

 if the sensor can not be calibrated any more and/or the instrument shows a corresponding error message

 if the sensor signal is very unstable.

6.2.

Stop of Operation for Maintenance

1 Shut off power of the instrument.

2 Stop sample flow by closing the flow regulating valve.

Maintenance

6.4.

Calibration

The sensing part of the sensor must not be in direct contact with water!

In the wet flow cell, the atmosphere will be saturated with water vapor. This atmosphere will produce the most accurate calibration results.

The required time for a calibration depends mainly on the difference between temperature and oxygen content in the sample and in the air. It can take 15 – 20 minutes. This is also the case, if the electrolyte was exchanged.

As soon as the reading is stable, the microprocessor will store the calibration data in the memory. The end of the calibration is indicated on the display.

To perform a calibration proceed as follows:

1 Navigate to menu <Maintenance> /<Calibration>.

2 Press [Enter] to start the calibration and follow the dialog on the display.

1 Calibrate the sensor according to chapter Calibration, p. 32 .

2 Prepare a 5%-sodium sulfite solution with demineralized water.

3 Put the electrode into the sodium sulfite solution afterwards. Assure that there are no air bubbles in front of the sensor.

4 The measured value should now be < 1 ppb.

NOTICE: Depending on the state of the electrode this process can take several hours. In case of an electrode-refill, this can take days until the measured value is lower than 1 ppb.

6.6.

Quality Assurance of the Instrument

Quality assurance level

Every SWAN on-line instrument is equipped with integrated, autonomous quality assurance functions to survey the plausibility of each measurement.

For the AMI Oxytrace / AMI Oxytrace QED these are:

 continuous monitoring of sample flow

 continuous monitoring of the temperature inside the transmitter 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 Oxygen 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.

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.

34

A-96.250.701 / 140716


Maintenance

 Level 1: Trend; Measurement used as an additional information to follow the process indicating trends.

 Level 2: Standard; Monitoring of several parameters of a process (e.g. oxygen, 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, maximal deviation of temperature and measuring result.

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 deviation 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-controller allows a proper control of the process.

Parameters: setpoint, P-Band, reset time, derivative time.
