Topic: PT-100 Interface Circuit ?? (Read 10686 times) previous topic - next topic


Hi All,

Does anyone have a simple circuit-diagram for an interaface ... Arduino - PT-100 ...

I would like to build such on a proto-board, and be able to measure temps in the range -10 to +100 Deg C, resolution is less important than repeatability, and accuracy to within a degree or so will be o.k.

I would prefer to use PT-100s, since these will be in an industrial environment.



I would like to understand this circuit. Does it give an output voltage that does linearly increase with temperature?
Can you give the source, application note or the like?
Thanks, Matze
