Connecting a PT100 RTD

Controllers Smoothie
1

The E3D PT100 amplifier board has three outputs connections - +ve, ground and signal.

So, I assume that ground goes to ground. +ve goes to a +3.3V supply. Signal goes to the thermistor pin and will vary between 1 and 3.3V

Is this a reasonable assumption? Any advice appreciated.
