hi kai,

i fully agrre with your point,

due to sensors own resistance (machanical,thermal or eletronic) to come back when action is reversed.

lets change this to make more expressive to:

due to sensors own resistance (machanical,thermal or eletronic) to come back to original state when action is reversed.

like PRTs, its is aasumed idealy that PRT does not has its own capacity to store heat, and no self heating. but in real when temprature increases PRT stores some energy it self which resists (when temprature decreases) change in temprature and in turn, the output value. could this be kept in hystrasis category.
