Overview
The pneumatic pressure control stages monitor the preset limit values. As soon as outlet pressure gets close to these limits during operation, the pneumatic pressure control stages take over and keep the pressure constant. The transition from electronic control to pneumatic control is done automatically and is operated smoothly in both directions.
The following operation modes may be realized between the two pressure limits:
Remote setpoint adjustment
The following operation modes may be realized between the two pressure limits:
Remote setpoint adjustment
- Adaptation of setpoints due to frequently changing operating conditions
- Integration with process control systems
- Gas storage in networks and tanks
- Meter protection by means of actual flow limitation
- Meter protection by means of actual flow limitation
- According to defined pressure curves throughout a day or week
- To improve regulating accuracy and stability due to electronic PI or PID control
- CE registration according to PED in combination with HON gas pressure regulators
- According to DIN EN 334, the pilot is an integral component of this device
