Pump pid control by pressure and temperature

varan_1270 Posts: 10 Rating: (0)	Hello Dears I want to control a pump by a temperature sensor and a pressure sensor at the same time. In fact, for example, the temperature set point is 50 degrees Celsius and the pressure set point is 120 bar. How can I control the device? I have given output PID_temp to inlet PID_compact but my pressure set point always keeps the pump on its set point

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
