Use an analog amplifier with gain = -1.25 and offset = +1250, Regards, Scorp |

Then you have to better explain where your problem is .... |

Why set you the gain in the PI Controller to 10? That make no sense... Let it be by 1. |

i don't know how to program the part to keep the pressure at 3bar |

If I understand you correctly, you want to prevent the pressure from dropping below 3 bar. I have created a program proposal for you. To get a better control range, I set the analog amplifier for a higher resolution (with two decimal places). The setpoint for the controller can be entered on the display. The controller is set for upward regulation. This means that if the actual value is greater than the setpoint, the analog output outputs 0 volts. The further the pressure drops below 3 bar, the more the voltage of the analog output rises to a maximum of 10Volt. AttachmentPI control_V2.zip (153 Downloads) |
