Application
The differential pressure controller DPC200 measures low pressure of non-aggressive gases, particulary of
air.
The customer can use an analog signal (0...10V). The device offers two different settings. On the one hand
the output signal stands for a pressure proportional signal during measuring mode or volume flow square root
signal.
And on the other hand the output signal stands for a PI closed-loop control signal for differential pressure
during control mode or volume flow during control mode.
This static pressure transducer with controller is primarily intended for air conditioning systems, room
pressure control and filter control with continuously varible speed fans.
The DPC has an additional alarm output (open collector) for limit value monitoring or for filter monitoring next
to the analog output.
