Openscale - Alternate Use of Ext Temp Input

Hello, I am trying to build a device that measures electrical resistance and weight at the same time. essentially I need to read the resistance of a fuel level sender as I add or remove fuel from a tank being weighed.

Can I use the external temperature sensor terminals to connect a voltage divider using my choice of fixed resistor? the resistance range needed to be measured is between 0 and 300 ohms. if anyone could help me out here I would be very grateful.

Once I have this connected, how would I create a calibration curve to read resistance in ohms rather than temperature. thanks for any help.

Unfortunately no, the external sensor connector is for a digital temperature sensor and is not setup for an analog reading. None of the analog capable pins on the board are broken out for use.
