Question #1, and most time-critical question:
Could I fill this signal conditioner with potting to make it effectively water proof?
It is mounted in a box outdoors and every time the weather changes, the box sweats, and the conditioner quits working. It is a load cell strain gauge amplifier. I got a quote for a "fully potted, waterproof" conditioner to replace it but it's real expensive and I've already got plenty of these non-potted units I could pot. I was thinking just shoot the plastic case full of potting and cover everything except for the ajustment pot screws. What'ya think?
Question #2 - just out of curiosity - Does potting things thermally insulate them? For example, If I filled an entire Variable Freq Drive with potting, would it cause it to overheat? I mean, all of the heat generating components are already attached to a giant heatsink which wouldn't be covered in potting... or how about if I snaked a tube all around through it and then potted, and then ran coolant through it... just brainstorming
...but why the heck would you want to do that?... which leads me to
question #3 - Does potting things protect them against physical shock (vibration, g-forces)? At some point I want to mount a VFD in a car, but they have a shock rating which is lower than what you'd find on a bumpy street, so could I effectively "ruggedize" a drive by shooting it full of potting?
Thanks,
Charlie
