Hi everyone!
I am hoping that you will be able to suggest best practices for avoiding degraded specks in molded parts. We make a lot of clear parts so they are very apparrent. We have a lot of ideas floating around but are hoping to identify industry best practices that we can follow.

Thanks to everyone for you input so far!

This is not a batch process. It will have to run continuously for several hours before being taken down for cleaning.
The main purpose is prevent overfill (wasted resin) or underfill (air gets mixed into the resin catalyst mixture).
Since we...
@controlnovice,
Level is the concern for overfill. I though about weight too but this hopper would be attached to a ~300 pound mixer and there would probably be less than a pound of resin in the hopper. I worry about being able to get good data from it.
@danw2,
Thanks for the ultrasonic...
@IRstuff,
Thanks for your suggestions so far. Any ideas who I could talk to (vendor?) that would be able to work with me through this problem? I don't have much experience with lasers.
If anyone else still has ideas I am open to hear them. I'm still trying to find a solution. Thanks!!

@IRstuff,
Yes the powder floats in the air. When I said it makes things cloudy I meant that the inside of the vessel has powder floating all over the place. We have to keep the vessel covered so that powder doesn't get all over the place.
Now that I think about it, the resin becomes cloudy in...
Hello everyone!
I've been racking my brain for a bit trying to figure out the best option for this problem.
I have an application with a very viscous resin and a powder catalyst being mixed in a small vessel (a very small one I will elaborate later). I would like to know the level on this...
Hi everyone!!
I am writing to see what everyones opinion is on spring loaded thermocouples.
I have seen them used and not used. What do you all do?
My opinion is that they should be used in all situations. I don't think there is a reason to risk having bad contact with the thermowell, and...
Thank you both for your feedback. It gave me quite a bit to consider. I understand that there are a lot of engineering decisions that still need to be made based off of the specific process that I am dealing with.
Thanks!!

Hello all,
I am working on placing some LEL and H2S detectors in a petroleum refining process unit. I can think of several ways that I think would work. But I would like to know if there are any official or standard procedures for designing the location of these types of sensors.
Clearly I...
