− For cost sensitive HVAC and medical OEM applications
− Unsurpassed performance thanks to CMOSens
− Offset and hysteresis free
− Excellent accuracy and reproducibility even below 10 Pa
− Fully calibrated and temperature compensated
− Linear or square root extracted output characteristics available
− Not sensitive to the mounting orientation
− Direct PCB mounting with simple snap-on system
The SDP1000 / SDP2000 differential pressure sensors
for air cover the following measurement ranges: –5 to
125 Pa (0.5 inch H
100 to 3500 Pa (14 inch H
Mounted in a rugged, chemically inert PPS housing the
SDP1000 / SDP2000 differential pressure sensors
feature a unique dynamic range, zero offset and
unsurpassed long term stability. This makes it an ideal fit
for demanding yet cost sensitive OEM applications in
HVAC and medical equipment.
The devices are supplied with 5.0 V and provide a
0.25…4.0 V output. Although the output of the
SDP1000 / SDP2000 differential pressure sensor is
analog, the internal linearization and temperature
compensation is performed digitally. This results in a
superior accuracy, outstanding resolution (up to 0.05
Pa), and lowest temperature dependence. The SDP1000
is available with a linear or square root extracted output
characteristics at the same price. Since fully
exchangeable just a few external electronic components

around the SDP1000 / SDP2000 make a high quality
differential sensor transmitter with e.g. an 0...10 V output
or other interfaces (see Figure 8).
Its leading performance is based on Sensirion’s
proprietary CMOSens
combines the sensor element with amplification and A/D
conversion on one single silicon chip. The differential
pressure is measured by a thermal sensor element. In
contrast to other thermal differential pressure sensors
only a very small amount of air is required (see
Figure 6). This leads to a reliable operation even under
harsh conditions. In comparison to membrane based
sensors the SDP1000 / SDP2000 differential pressure
sensors show an extended measurement range, better
offset stability and improved reproducibility even at
lowest pressure ranges (see Figure 1 and 2). In addition
the SDP1000 / SDP2000 is robust against pressure
bursts and shows no sensitivity to the mounting
orientation.
SDP1000 / SDP2000 is fully RoHS compliant.
