They have several pressure transducers. They manufacture Weigh-in-Motion
equipment for weighing vehicles on the highway. They have two pressure
transducers that may fill your needs; capacitive and DYNAX(r) I think.
I've seen the DYNAX sensor, it can act as a pressure switch. They say
that it can also be set into a more linear transducer range. It is
supposed to be cheap, but I've never actually purchased it.
