Details
- Series 902
The pressure to be controlled generates a force (bellows or diaphragm), which is compared by the measuring system with the force of an adjustable spring and generates the actuation pressure via a nozzle/flapper system. A feedback from the actuator stem is used to stabilize the controller. The pressure controller type 902 can be used e.g. for the control of steam or liquid pressure and as a pressure controller for gas in process plants.
