Pressure sensor/transducer 0 -> 100psi

[jmumby]

Does any one know of a sensor that will measure pressure up to 100PSI, not fussed on output preferably digital. I have seen a few out there but they are hugely expensive!

It will used to measure pressure within a water bottle rocket.

Thx,

Jason

I just bought a unit from ebay $28. ppd - in stainless steel package 1/8" MPT thread -5volts in .5 to 4.5 v 0-100 psi out linear +/- 2% FS so less accurate. I haven't fully tested it yet... looks ok... http://www.ebay.com/itm/261260635816?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Not clear to me how the one referenced above is hooked to the pressure source...

This website : http://meas-spec.com/application-notes.aspx has lots of info on using pressure sensors, including how to use these type of devices.

( Unfortunately the website keeps locking up for me. YMMV )
