SDP1000 / SDP2000 Product Summary

The SDP1000 / SDP2000 differential pressure sensors

for air cover the following measurement ranges: –5 to

125 Pa (0.5 inch H₂O), -20 to 500 Pa (2 inch H₂O), and -

100 to 3500 Pa (14 inch H₂O).

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^®sensor technology which

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.
