Output Signal
(1)
Proportional-Only, Proportional-Plus-Reset, or
Proportional-Plus-Reset-Plus-Rate Range: 3 to
15 psig or 6 to 30 psig (0.2 to 1.0 bar or 0.4 to 2.0

Action: Field-reversible between direct(increasing
sensed process pressure increases output pres-
sure) or reverse(increasing sensed process pres-
sure decreases output pressure).
Process Scale
Standard scale is matched to the range of the sens-
ing element, with the exception of receiver control-
lers. Optional
