Air Suspension Gauge

yep, wabco ore knorr bremse sensors. Work with 8-32 V supply, wabco 441 040 101 0.

So you need to build small analogue-digital converter and calibrate it according load to pressure function (usually linear). You can use it with telemertic systems too.

 

ouh... really you can use microprocessor with built in analogue ports and use it.... But this is quation for electronic designers. It is not all, you have to make a chart PSI to LBS for every axels.

 

Maria, you can use one of these to collect the data.

It will do the job but requires some basic programming to make it work. I have used other convertyors like this in the past to collect data similar to what you are doing but I have done minor programming in the past and am quite good with computers. If you are in that catagory give it a try, you can do lots of fun things with a I/O board.

 

How about using a pen and paper. Seems a lot easier

 

Wow. So theoretically if you had a sensitive enough pressure sensor you could put it in the appropriate orifice with an airtight seal and collect data on flatulence.
