Catalog excerpts

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. Specifications Measuring medium: Measuring principle: air or non-aggressive gases silicon diaphragm with spring and differential transformer approx. 10 mA @ 10 Vdc, approx. 12 mA @ 24 Vdc 0...10 V (Imax = 0,5 mA @ 10 Vdc, Imax = 2 mA @ 20 Vdc) Open Collector, max. 30 V / 30 mA Display: Mode: Controlling algorithm: Set points: 0...50 Pa 0...6000 Pa 0,2 bar max. 0,2 bar hose liners 5 mm ø and 6 mm ø UL 94 HB; Case polyamid, cover ABS 10...30 Vdc or 24 Vac ± 15 % Electronic protection against faulty polarization Current consumption: Output: Lowest span: Highest span: Overpressure protection: Static pressure: Pressure Connections: Case: Supply voltage: LCD-Display, 2x16 characters measuring mode or controlling mode PI 2 set points adjustable within software, set points are selectable with floating contact input Protection class: Ambient temperature: Weight: Mounting: Interference emission: IP 54 according EN 60529 0...+50 °C approx. 90 g vertical, position dependence by turning of 90°: approx. 25 Pa tested according EN 61000-6-2, EN 61000-6-3, CE mark Influences limits: zero error: sum of linearity and hysteresis (depends on measuring range): temperature drift, zero point: temperature drift, span:
