look in the Summit or Jegs catalog -- they sell isolators.

also check out the pressure transducers in the Digi-Key
catalog (p. 454 in May-June).  The Measurement Specialties
SS xducer costs ~ $85 and will work, but you're going to
have to have some electronics (i.e. op-amp signal
conditioning) to make it work
