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. They are available for proportional only, proportional-plus-reset, and differential gap control. The controller is also available with anti-reset windup, internal auto/manual station, and remote set point adjustability. 4194 controllers are used in industries where process monitoring and accurate measurement of differential pressures are required.
Features
1.Simple design of the controller allows fast, easy maintenance and minimal spare parts inventory.
2.Adjusting the set point and the zero and span of the process pointer and switching between direct and reverse action are accomplished quickly and without special tools.
3.Relay and nozzle design reduces steady-state air consumption to as low as 0.09 normal m3/hr (5 scfh).
4.The controller can mount directly on the actuator or it can mount on a pipestand, on a wall, or in a panel.
