The DPCs are electromechanical differential pressure / volume flow controllers with a diaphragm measuring system and a comprehensive evaluation software. They are used to measure and control the smallest differential pressures of non-aggressive gases, in particular of air.

Their optimal application area can be found in the field of climatic technology for controlling fans, room pressure monitoring or filter control. The devices allow controlling of air flow or keeping up a constant pressure in a closed environment.

In addition to the analog output, an additional alarm output (open collector, max. 30 V / 30 mA or relay 250 Vac / 10 A) is available for limit monitoring or filter monitoring. The device provides a radiated output signal as a volumetric flow sensor. In the case of the pressure or volume flow control, the output signal is the manipulated variable of the PI control.
