Fisher Controller and Instrument
Fisher 4194 Differential Pressure Controller
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.
- Fisher 4194 simple design and low mass of internal parts allow the controller to withstand vibration encountered in most plant environments.
- The controller can mount directly on the actuator or it can mount on a pipestand, on a wall, or in a panel.
