[Land-speed] Inexpensive Pressure Transducer

[neil at dbelltech.com]

Mayf, Jon;

Digi- Key is a great source for all sorts of electronic components. If you
can't find a pressure transducer there, try Omega Engineering-- they have
all sorts of transducers, sensors, etc. 

Here is one example:

To get a calibrated 5V output you need to provide it with an 8V source. This
can be a simple voltage regulator (not an automotive voltage regulator) that
is connected to your 12V system.

I get all my transducers at DigiKey. They have a comprehensive website for 
just about anything in that arena. They are great sensors have just about 
anything. I believe I spent about $80 on one for my fuel system. It was 
1/8" pipe and takes a 5v reference voltage. There are others that take a 12V

ref if that is what you need for your system. I think Mayf's application and

systems used are all a 5v reference.
