SDP2000-R is a low-range analog differential pressure sensor from the Sensirion SDP1000 / SDP2000 series. It measures in the 0 … 3,500 Pa range and provides a square-root extracted 0.25–4.0 V analog output. The square-root characteristic gives a signal proportional to flow in airflow measurements with restrictors such as an orifice or venturi, reducing the need for extra calculation.
Key features
- Square-root extracted analog output (0.25–4.0 V)
- Fully calibrated and digitally temperature compensated
- No offset or hysteresis, insensitive to mounting orientation
- High accuracy and repeatability even below 10 Pa
- PPS housing, snap-on PCB mounting
