Good day all,
How does one go about scaling a pressure transmitter that indicates both Vacuum and pressure? The transmitter I have has a range of Vacuum to 75 PSI. I am trying to wrap my head around scaling this with an AllenBradley 1768-IF8 AI card. Application in which this transmitter is used, exposes it to both Pressure and vacuum conditions. So, if my Scale max value is 75psi what is my scale Minimum value? Instead of psi it will be mmHg is what I am guessing. Or, is it 0 psi? Can anyone point me in the right direction?
Thanks!
