Differential pressure / Volume flow controller DPC200R - 1

DIFFERENTIAL PRESSURE / VOLUME FLOW CONTROLLER DPC200 Electromechanical diaphragm measuring system Measuring range from 0...50 Pa (0.5 mbar) up to 0...6000 Pa (60 mbar) Alphanumeric LCD-display Analogue output 0...10 V Selectable measurements (differential pressure or volume flow) Selectable units (metric or imperial) Adjustable k-factor for volume flow calculation Controlling mode or measuring mode selectable Measuring mode with adjustable limit value Control mode with adjustable: - 2 setpoints - PI parameters for PI algorithm - maximum output voltage Supply voltage 10...30 Vdc; 24 Vac (+/-15%) Compact plastic housing IP 54 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.
