Using a resistance output sensor on MC43

A customer has purchased a resistance output level sensor (240-33 ohms). I have tried to find more information regarding converting this to a VIN, but couldn't find too much. I am wondering what else needs to be done other than incorporating a voltage divider in their circuit.

You can create a voltage divider with a suitable resistor which you feed from a Vref output and connect the other end of the sensor to ground.

Then just write a conversion table and it should work.
