Hayashi Denko makes a Pt100 sensor about 3x7x1mm. It's a ceramic chip with
a film coating and wire leads. Model 2005 comes in a relaxed tolerance
class that is less expensive than the standard model. As Wagner noted,
precision may be more important than accuracy in your application. I think
their US distributor is CRZ, but no way to know who it would be in Brazil.
