USA bluebook sells pres. transducer along with a ton of other stuff related to water. Their tech support is excellent too if you need help choosing the right one.
I've come to favor Omron sensors of all types over the years. The price point is certainly right, and the performance is on par with anything else. The E8AA pressure transducer is one I have used before and proved to me that it is quite linear. It goes 0 to one-million pascals, which is basically 0-150 psi.
I second the Hydac units. I use them in electrohydraulics extensively. The HDA4475 line is the lower price family and is available in the range you need. The link above is general; the one I suggest is at http://www.hydacusa.com/literature/electronics/hda4400_4700.pdf
I used to work for the local distributer, and have seen hundreds in service. It is available in both 4-20 and 10V versions.
