[PSUBS-MAILIST] Pressure Transducer

[Jon Wallace via Personal_Submersibles]

 Turns out this issue was nothing more than miscalculating the 1ATM point of the sensor because it is an absolute gauge.  I got that sorted out and was able to do some real world testing from 100psi to 1psi and the sensor is spot on with the calculated values for the transducer, as well as two other analog gauges used for comparison.  Quite happy with it now.

 One obvious error source is that barometric pressures reported by weather sources correct the local pressure readings back to sea level (WGS 84 0'). You need to correct the reported pressure for your local altitude, or measure it directly using your own instrument.
