User manual Accuraspray4.0
The different measurements provided by the Accuraspray are described in
details in the table below.
Parameters Description
Temperature Average particles temperature that are passing
through the sensor’s measurement volume
(bullseye).
Velocity Average particles speed that are passing through the
sensor’s measurement volume (bullseye).
Intensity Intensity of the spray plume.
This measurement is very sensitive to minute
changes in the spray conditions. The parameters that
have the strongest effect on the plume intensity are:
•
Particles temperature;
•
Average particles diameter;
•
Feedstock emissivity;
•
Feed rate.
Plume density Provides an indication of the particles flow rate.
Part temperature Temperature of the substrate on which the coating is
applied.
Plume deviation Deviation of the plume position against the bullseye.
Plume width Width of the spray plume.
3.2.1.1 Zoom in / out
It is possible to zoom in on the center of the image where the bullseye is
located.
To do so, click on the magnifying glass icon. This will enlarge the image so
that the sampling line, the dotted vertical line overlaid on the camera image,
takes 50% of the screen. To return to the full screen click on the magnifying
glass again.
This feature is especially useful for HVAF/HVOF where the plume is quite
narrow and can be difficult to see when viewing the full camera frame.
3.2.1.2 Recording a video sequence
Sequences can be recorded and recalled using the icons on the top left
corner of the video. The camera icon is used to launch a recording.
Once the Accuraspray is recording, the letters in the camera will turn red to
indicate that the Accuraspray is recording.
To stop recording, click on the square icon next to the camera. This will
automatically download the sequence to your computer in your web browser
default download directory.
