* 110 : Pt100 with 1kΩ pullup (atypical)
* 147 : Pt100 with 4.7kΩ pullup
* 1010 : Pt1000 with 1kΩ pullup (atypical)
* 1022 : Pt1000 with 2.2kΩ pullup
* 1047 : Pt1000 with 4.7kΩ pullup (E3D)
* 20 : Pt100 with circuit in the Ultimainboard V2.x with mainboard ADC reference voltage = INA826 amplifier-board supply voltage.
* NOTE: (1) Must use an ADC input with no pullup. (2) Some INA826 amplifiers are unreliable at 3.3V so consider using sensor 147, 110, or 21.
