I am developing a ROV and I’m using the Bar30 Pressure Sensor. I’m having some issues for measuring low depths with adecuate accuracy. Also, I’m experiencing the same drift problem as other users describe in other posts.
I have some doubts about the pressure sensor datasheet. I think that solving them, may help me.
First, in the pressure and temperature calculation chart there are some notes at the bottom which says:
“min and max have to be defined” for the variables dT, OFF and SENS.
I don’t understant it. Can I define min and max for those variables? How do I do that? Would that help in the absolute accuracy? I think that in your library you don’t define it. Does it have some thing to do with the OSR selected?
Another question: In the pressure output characteristics, What does it mean the note (1) “Whit autozero at one pressure point” for the absolute accuracy?
Thank you in advance for your help!
