I'm looking for sources of oxygen sensors ( 0 to 100% ) like used in gas
analysers. I know that these exist as semiconductor devices ( real small )
Want to make a nitrox analyser for scuba diving.
Most sensors for DIY analyser i find out there are big and bulky. Can be no
bigger then a transistor.
Second thing i'm looking for is a Pressure sensor ( Absolute pressure )
that can withtstand at last 4000 PSI ( 350 BAR ) and has a threaded
coupling. No strain gauge type ! has to be semiconductor or capacitive
type.Preferrable with compensatin electronics inside. Like 0 to 5 volts is
0 to 5000 PSI. I don't want to deal with non linearities and temperature
drift of these things. Motorola and Melexis make neat sensors but they
don't go that high in pressure..
Anyone know who makes the sensors used in dive computers from suunto /
Mares / Uwatec ? That is what i am looking for. Has the right connection
and everything.
