Fisher 4194 differential pressure indicating controllers show process differential pressure and set point on an easy-to-read process scale. The controllers sense two different pressures and compare the difference between these pressures with an operator-adjusted set point. They are available for proportional only, proportional-plus-reset, and differential gap control. The controller is also.. A differential pressure controller consists of a valve and a pressure actuator. Differential pressure controllers in the primary system are mainly used to keep a constant and lower differential pressure across a motorized control valve or a total system/substation. As a rule of thumb, the differential pressure controller should be used whenever the ratio between maximum and minimum available.
