Notes: (1) Differential pressure models can be used to measure gage pressure by leaving
the reference port open to atmosphere.
(2) Line pressure refers to pressure applied to both high and low sides of the sensing
device simultaneously. Refer to the product data sheet to determine maximum
differential pressure and overpressure limits.
