Hello experts,
I have a question regarding measuring very small pressure with SITRANS 7MF4332-1D transmitter.
I have read how this transmitter works in general manual. However I'm not sure about one thing. I have read that this transmitter has a measuring span from 8.3 mbar to 250 mbar. This is below normal atmospheric pressure. Is it possible to calibrate transmitter in the following way: LRV: -50, URV 50 mbar? I have heard of this but don't know how to interpret it. I suspect that this value of -50 mbar means 50 mbars below normal atmospheric value of P = 1.013 bar.
I think that this transmitter has reference vacuum which is very small pressure (smaller than 8.3 mbar), and that it measures actual pressure. Can someone explain this in more detail?
