Hi all,


I have an issue with a high level switch in a vessel that activates periodically when we charge powder into the vessel.


It is a vibrating tuning fork design.


Is there any other model types that could be used that might be more suitable at not falsely activating when powder charging?


The vessel already has a radar probe installed and this high level is additional protection against overfill.

Hi ,

My experience with fork on powder is similar to yours . How big is your silo?

By chance can you install load cells or a second radar ? more expensive but works.


Note : Take a look at the link underneath , you may contact them for your application :



Good luck

Or maybe you could give the tuning fork a shade?
