Can't beat Rosemount pressure transducers. Kind of pricy but you get what you pay for. If you want less expensive goto Omega.com. They have a wide variety of pressure transducers from various manufactures (including Rosemount) sold under their own brand. You probably want one with a built in amplifier to provide a ma or voltage source for your logger. For a logger, the easiest would be something from NI that would plug into your computer. if you want an external logger the NI field point is good and I really utilize the Fluke 34970A logger. Lots of channels, very inexpensive and will accept many types of inputs from dc voltage to thermocouples and RTDs. There is a driver available from NI for the 34970A and it uses the RS232 port. It's a multiplexed instrument so it won't be as fast as say a PLC or field point. That is, it has one measuring circuit and each channel is multiplexed in one at a time. Still you can scan 20 channels a second with reasonable resolution.
