Description
Output is proportional to the difference between 0psiA (Pmin) and pressure
applied to Port 1.
Output is proportional to the difference between Port 1 and Port 2. Output
swings positive when Port 1> Port 2. Output is 50% of total counts when
Port 1=Port 2.
Output is proportional to the difference between 0psiG (Pmin) and Port 1.
Output swings positive when Port 1> Port 2.
Output is proportional to the difference between -15psiG pressure (Pmin)
and pressure applied to Port 1.
