You need a sensor that can be powered on 12VDC but has an Analog output of 0-5VDC over the pressure range you're trying to read. I've used sensors from Transducers Direct with my LM-2 with good success. They're around $100. Not to say you can't find a lower cost one on eBay, just make sure they are designed to have 12V input power.
