SDP600 Datasheet, PDF (1/10 Pages) List of Unclassifed Manufacturers – Accuracy better than 0.2% FS near zero

SDP600 Series (SDP6xx/5xx)
Low-cost Digital Differential Pressure Sensor
 Accuracy better than 0.2% FS near zero
 Digital output (I²C)
 Excellent repeatability, even below 10 Pa
 Calibrated and temperature compensated
 Excellent long-term stability
 Flow measurement in bypass configuration
Product Summary
The SDP600 sensor family is Sensirion’s series of digital
differential pressure sensors designed for high-volume
applications. They measure the pressure of air and non-
aggressive gases with superb accuracy and no offset drift.
The sensors cover a pressure range of up to ±500 Pa
(±2 inch H2O / ±5 mbar) and deliver outstanding accuracy
even at the bottom end of the measuring range.
The SDP600 series operates from a 3.3V supply voltage
and features a digital 2-wire interface, which makes it easy
to connect directly to a microprocessor. The signal is
internally linearized and temperature compensated.
The outstanding performance of these sensors is based
on Sensirion’s patented CMOSens^® sensor technology,
which combines the sensor element, signal processing
and digital calibration on a tiny microchip. The differential
pressure is measured by a thermal sensor element using
flow-through technology. Compared with membrane-
based sensors, the SDP600 features an extended
dynamic range, better long-term stability, and improved
repeatability, especially near zero.
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.
Applications
 Medical
 HVAC
 Automotive
 Process automation
 Burner control
Sensor chip
The SDP600 series features a fourth-generation silicon
sensor chip called SF04. In addition to a thermal mass
flow sensor element, the chip contains an amplifier, A/D
converter, EEPROM memory, digital signal processing
circuitry, and interface. The highly sensitive chip requires
only a minuscule amount of gas flow through the sensor.
OEM options
A variety of custom options can be implemented for high-
volume OEM applications. Ask us for more information.
