	I am designing a unit where I need to monitor air pressure from 0-1 bar. This information will be fed to a micro controller. The ideal input to the micro, is a variable resistance and whilst this type of transducer is available for temperature, light etc. I can't find one for pressure. Not only are the available pressure transducers expensive and output to a Wheatstone Bridge, they require additional circuitry for input into a micro. Any help is appreciated. Does anyone know if a car oil pressure sender is resistive? __________________ The nice thing about Standards is there are so many to choose from.

	Perhaps you can find what your looking for here: http://www.emersonprocess.com/Rosemount/products/Pressure/index.html I use these in a simular range with a 4-20ma output, that most controllers can handle. __________________ I go into every human encounter expecting to be framed for a crime I didn't commit.

	Sensirion.com (Swiss) do ones with SPI and RS232 outputs... along with loads of other sensors... __________________ A little knowledge is a dangerous thing - Googling is far worse!
