Glad to hear that you got it sorted out. Sensor gremlins can be frustrating.

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.
