Engine condition monitoring diagnostic tester project

		I have seen engine pressure transducers that can measure
combustion pressure used in stationary industrial engines. This application
measured the pressure every 2 degrees of crankshaft rotation on all
cylinders (4000hp natural gas compressors). This information was collected
and sent to a central location in Salt Lake City for logging and analysis. 

		Try looking in an industrial supplier catalog like
Graingers.

I am building an compression tester/Leak down tester to interface to a
PC and log the compression curve and leak down curve to enable piston
and vavle condition to be monitored and compared.  Anybody got any ideas
on suitable low cost pressure sensors.
