SDP2000-L is a low-range analog differential pressure sensor developed by Sensirion for air and non-aggressive gases. It measures in the -100 … +3,500 Pa range and provides a 0.25–4.0 V linear analog output. Although the output is analog, linearisation and temperature compensation are done digitally. It has no offset or hysteresis, is insensitive to mounting orientation and mounts directly on the PCB.
Key features
- -100 … +3,500 Pa measurement range (calibrated 0–3,500 Pa)
- 0.25–4.0 V linear analog output
- Fully calibrated and temperature compensated
- No offset or hysteresis, insensitive to mounting orientation
- Chemically resistant PPS housing, snap-on PCB mounting
