SDP2000-L

P1-P3P4-P6P7-P8
www.sensirion.com Version 1 – April 2017 1/8
Datasheet SDP2000-L
Differential Pressure Sensor with Analog Output
Calibrated and temperature compensated
Excellent repeatability, no drift
Product Summary
The SDP2000-L differential pressure sensor for air covers a measurement range of 3500 Pa (14 inch H
2
O).
Mounted in a PPS housing the SDP2000-L differential pressure sensor features 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 device is supplied with 5 V and provides a 0.25…4 V output. Although the output of the SDP2000-L differential
pressure sensor is analog, the internal linearization and temperature compensation is performed digitally. This results in
superior accuracy, outstanding resolution, and lowest temperature dependence.
The outstanding performance of the sensor is based on Sensirion’s patented CMOSens® sensor technology, which
combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure
is measured by a thermal sensor element using flow-through technology. The well-proven CMOS technology is perfectly
suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.

1.1 Temperature Compensation
The SDP2000-L differential pressure sensor features a sophisticated built-in temperature compensation circuit. The
temperature is measured on the CMOSens chip by means of a bandgap reference temperature sensor. Its data is fed
into a compensation circuit which is also integrated on the CMOSens
®
sensor chip. No external temperature
compensation is therefore required.
1.2 Altitude Correction
The SDP2000-L differential pressure sensor achieves its unsurpassed performance by using a dynamic measurement
principle, i.e. an applied differential pressure forces a small air flow through the sensor. This results in a dependence of
the indicated differential pressure on the ambient air density. While the temperature effect is compensated (see
Paragraph 1.1) the altitude above sea level has an influence on the SDP2000-L output. If desired, this effect can be
compensated by a correction factor according to the following equation:
Dp
eff
= Dp
sensor
*
P
cal
/ P

where Dp
eff
is the effective differential pressure, Dp
sensor
the differential pressure indicated by the SDP2000-L, P
cal
the
absolute pressure during calibration (966 mbar) and P
amb
the actual ambient absolute pressure.
Note:
For more detailed information about temperature and pressure compensation, refer to the selection guide in the
differential pressure download center on the Sensirion website.
