DIFFERENTIAL PRESSURE CONTROLER DPC200 Diaphragm element with differential transformer Measuring range from 0...50 Pa up to 0...6000 Pa Alphanumeric LCD-display Analogue output 0...10 V Controlling mode or measuring mode selectable Controlling mode with PI algorithm 2 set points adjustable Selectable measurements (differential pressure or volume flow) Selectable units (metric or imperial) Maximum output voltage adjustable Supply voltage 10...30 Vdc; 24 Vac (+/-15%) Compact plastic housing IP 54 The differential pressure sensor DPC200 serve for measuring low pressure of non-aggressive gases, particularly of air. The customer can use an analogue 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 the output is the square root signal during volume flow measurement. And on the other hand the output signal stands for a PI control signal during controlling mode. The device can control differential pressure and volume flow. This device is mainly for e.g. in air conditioning systems for fan controlling, for pressure control of rooms or filter controlling.
