Pressure Meter
Sometimes it's good to monitor 2 pressures at the same time. For example when adjusting a FID=Flame Ionization Detector.
I built the meter around a Pic 16F876, which have a 10bit A/D. Not a high resolution, but sometimes it is enough.
The transducer used is a differential type, MPX5100DP with the range of +- 1000mbar. Linearity is 0.1% Fs.
This pressure tester has 2 transducers, which makes it possible to measure Air and Fuel at the same time. The red connector is for pressure the other for vacuum.
The next model should have a flowmeter as well, then it will become a complete FID test tool.
