Differential pressure sensor with a wide selection of ranges for unidirectional (0 to 1000 Pa) and bidirectional measurements (up to ±500 Pa), ideal for accurate low-pressure monitoring. Pressure units (Pa, mmH₂O, mbar, inWG, mmHG, daPa, kPa, hPa) and response time (0.5 / 1 / 2 / 4 s) are selectable via DIP switches, with ±1% accuracy. 4–20 mA output (2-wire) with 12–30 VDC supply, IP54 protection and 15 kPa overpressure tolerance, operating temperature -10°C to +60°C, and storage temperature -10°C to +70°C.
