2. OVERVIEW There are two types of measurement cell packages available for the Courier analyzer:

Analyzer probe with Automatic Window Changer (AWC)

Analyzer probe with Sample Cell Assembly (SCA)

These measurement cell types are described in more detail in the following section.

Code Revision A Page 5 (30) 10000006053e

2.1 Analyzer probe with AWC The AWC is a mechanism that performs an automatic window change. When changing the window, the AWC automatically releases the measurement cell and the measurement cell window film, winds the window film forward approximately 10 cm, and tightens the measurement cell window film and the measurement cell.

The window film lasts up to 700 window changes, and therefore, the window film storage reel needs to be changed manually at approx. six month intervals. If there is a malfunction in the measurement cell mechanisms, e.g., the motor is down, you can also change the window film manually.

The analyzer probe with AWC is comprised of:

Measurement cell

Window film reels

Window film material

Capstan motor

Cylinders and their valves

Moisture leakage detection

Functionality

The AWC can either be used for a window change that is automatically repeated in a certain interval or for a window change that is triggered by using the commands on the Probe Control Set display. The default interval, which is the actual time the sample has flown through the measurement cell, for the automatic window change is 8 hours. The interval can be changed in the user parameters. You can also set the AWC not to do automatic window changes at all with an analyzer parameter.

Each window changing operation includes four different phases that are run automatically. The phases are:

The measurement cell is flushed

The measurement cell is drained

The measurement cell window is changed

The water test is run

The measurement cell window change is based on a pulse mechanism that stops the film winding when the proximity sensor has counted a certain amount of pulses for new window film. The measurement cell window change in itself includes five phases:

Releasing the measurement cell and the measurement cell window

Starting the window winding motor

Changing the window (winding the window forward)

Stopping the window winding motor

Locking the measurement cell window and the measurement cell

After the automatic window change and a successful water test, measurements are continued normally.

2.2 Analyzer probe with SCA In the SCA, the automatic window changing functions cannot be used and the measurement cell maintenance tasks must be performed manually.

The measurement cell area is comprised of:

Measurement cell

Discrete measurement cell window

Measurement cell window clamping ring

Protective window ring

Moisture leakage detection

3. RADIATION SAFETY The analyzer, and the measurement cell, meets all the radiation safety regulations of the European Union. No radiation can be detected inside or outside the probe covers. Radiation safety is guaranteed by using redundant fail-safe sensors with hard-wired interlock circuits that shut down the X-ray power.

Radiation in use indicator

The X-ray ON indicator lights are located on the roof of the analyzer probe and on the control panel of the Probe Control Set. The X-ray ON light indicates that the interlock circuit is closed and the high voltage power supply of the X-ray tube is on. The X-ray OFF lights indicate when the interlock circuit is open and the high voltage power supply is off.
