Closed loop control: differential pressure with 2 pressure sensors 4...20 mA
A constant differential pressure of 4 bar is needed. A 4…20mA pressure sensor on the high pressure side with a measurement range of 0-
6 bar is connected to analog input 1. A 4…20mA pressure sensor on the low pressure side with a measurement range of 0-2 bar is con-
nected to analog input 2. The set point is given by the display.
