A 4 wire PT100 sensor. Let's be honest, this is excessive. It's Class A as well.
- Class A ± (0,15+0,002 * t), ±0,15 °C (0 °C), ±0,35 °C (100 °C), defined on range -100…+450 °C (wire wound resistor)
With an Octopus Pro, you need no additional hardware. This is, literally, the most accuracy possible on a 3D printer hotend.
You'll need all 4 wires back to the board, so if you're running a toolhead PCB you'll likely need an additional couple of runs for this. If you really want, you can just use one white and one blue wire and use it in 2 wire mode, but why would you do that?!
