Sensirion SDP1000-R: offset-free low-range differential pressure sensor with 0–500 Pa range and square-root extracted 0.25–4.0 V analog output.
SDP1000-R is a low-range analog differential pressure sensor from the Sensirion SDP1000 / SDP2000 series. It measures in the 0 … 500 Pa range and provides a square-root extracted 0.25–4.0 V analog output. With CMOSens® technology the sensor element, amplification and A/D conversion are on a single chip. It has no offset or hysteresis, is insensitive to mounting orientation and is ideal for HVAC and medical OEM applications.
Key features
- Square-root extracted analog output (0.25–4.0 V)
- 0–500 Pa measurement range
- 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
