The DPC200 differential pressure regulator is used to measure small differential pressures of non-aggressive gases, especially air. A signal of 0...10 V is available to the user as an analog output. Depending on the setting of the device, this signal has different meanings. If the instrument is used as a pressure sensor, the output signal is proportional to the measured pressure. As a volume flow sensor, the device provides a root-equipped output signal.

In pressure or flow rate control, the output signal represents the manipulated variable of the PI control.
