Tenth part, amendments to previous parts and tying up some lose ends …
↓↓↓ Complete description, time index and links below ↓↓↓

In the ninth video I’ve discovered – far too late – that capacitive liquid level sensors work differently for conductive and non-conductive liquids – my deepest apologies for that (link below). So I have to make some amendments now.

First we go over the first eight parts and have a look at what was applicable, respectively, inapplicable, for conductive, respectively, non-conductive liquids. Then we tie up some lose ends. Just some stuff we didn’t cover in the previous videos.

00:00 Intro – errata, amendments and lose ends
01:25 Errata and amendments – to parts one through eight
04:37 Coax cables – good shielding, but add a lot of capacitance
06:22 Polar and non-polar – material choice for isolation
11:37 Optimizing parameters – for RC charge curve measurements
15:17 Wrap-up – enough of that, bye
