I am a bit in trouble with finding a double insulated 10k NTC sensor and I am questioning what double insulation really means.
Does double insulation mean, that there are really two different isolation materials on top of each other or is it enough, that the insulation material has double the thickness and so double the insulation resistance that is necessary for single insulation?
I contacted several manufacturers and the answere is mostly, that there is no breakdown at a specific voltage, for example 1500V.
Here is also an example from an NTC datasheet I found. Can one say from there if this NTC is double insulated?
