What do the camera shutter auto ranges represent for Solo/Reflex?
These ranges affect the minimum and maximum allowed shutter speed for the camera. However, these values are not represented in any units of time. Unfortunately, these ranges for the shutter speed cannot be easily converted to milliseconds (the conversion changes depending on many factors). Therefore, you will need to use trial and error by increasing/decreasing the values and taking note of the resulting shutter speeds displayed directly above these range values. To try and further explain, below is an example of its behaviour. However, the below numbers are NOT necessarily correct and are used only for demonstration.
Let’s say a system has the shutter limits set to 10-100.
You introduce a lot of light and find the shutter never goes below 0.3ms (while the image remains too bright), then 10=0.3ms.
You take away light and the shutter never goes above 3ms (while the image remains too dark), then 100=3ms.
However, the entire shutter range of the camera cannot be expressed with a linear equation and you will probably find that solving for values outside of this range will be incorrect. For example, you may expect 1=0.03ms, but you should expect to find that this is incorrect once you actually enter these values into the software.
Can Reflex be calibrated?
Reflex cannot be accurately calibrated.
Can WipFrag Momentum be Calibrated?
WipFrag Momentum can be calibrated. The process does take some time and requires multiple analyses and sieve samples.
Stop belt with the material present.
Manually capture an image with Momentum, analyze the image and save results.
Remove the section of material from the belt (that was in the image) and sieve.
Repeat this procedure at least 5 times to get adequate representation of the material. Email all of the results to firstname.lastname@example.org. We will use our calibration tools to get a Rosin-Rammler or Swebrec calibration target and email you back the figures. You can then set these values by connecting to the system using WipFrag 3.
Edge Detection Parameters
Note to online system users:
Please remember that if you change the zoom on your cameras or alter the lighting, you will most likely need to reset your EDP. Take 20-30 images over a day and find an EDP that works well on all of them. Recheck the EDP after 1 week to verify it is still working well. EDPs should not be altered during studies, projects, etc. Unlike scaling errors, EDP mistakes cannot be corrected for when post-processing the data. EDPs will not work perfectly for all images. A few small fusion and disintegration errors are common in all photo analysis software.
Do we need another system to monitor more feeds?
WipFrag Momentum systems are designed to accept up to 6 cameras into a solitary workstation.
We are looking for an online analyzer for an alumni export plant.
WipFrag Momentum would allow you to monitor material on as many as 6 conveyor belts at one time in real time. If you need to measure anything from prills and pellets to fines and boulders, WipFrag Momentum may be what you are looking for. Please contact us and we can send you more information on the topic.
