Anyone got any experience with pressure and integrated components. Does the produsers make sure the components don't contain small air pockets so it won't implode, or do I have to pressure test everything.
The datasheet for this hall sensor doesn't say anything about this condisions.
Anyone got experience with this?
why? I want to up it underwater, 50 bar. Will it survive?

I just talked to the manufacturers, it had never been tried, but the material will absorb some water so it's not sutible for long term use. But for a short amount or time, it will do the job.
you might try this: cast the entire circuit in water clear epoxy. It is absolutely water tight, and small air enclosures shouldn't matter at 50 bar. Small pressure tanks with a maximum pressure of 300 bar (~4,800psi) and a volume of max 3 liters are allowed for use without x-raying the welding spots. So I guess 50 bar is a pretty low pressure value compared to that.
The lesser the air enclosures in the epoxy the more will be the usable depth. If there is nothing to compress (gases) the depth is unlimited.
