That sounds like a job for a simple microcontroller, although there are other methods that would probably work out more complex and more expensive.
Can you say:
What is the part number of the sensor - a link to a datasheet would be good?
What accuracy, precision, range and resolution do you need? For instance, 0-1kPa in 1Pa increments, or 90kPa-110kPa displayed on 3.5 digits... Be realistic, say what you need, not what would be nice. The more you need here, the more it costs!
It might help to tell us the application. It's probably simple enough from the electronics point of view, once we know the details.
...
The simple, first-pass solution is an MCU like a PIC18F, a standard wall-wart power supply to feed the on-board regulators, and probably a few op-amps to condition the sensor signal. Oh, and an LCD display.
Does the system have to do anything other than just display the pressure?
