SFM3300-AW Datasheet, PDF (1/7 Pages) List of Unclassifed Manufacturers – Flow range: ± 250 slm (bidirectional)

Preliminary Datasheet SFM3300-AW
Digital Flow Meter for medical applications
 Flow range: ± 250 slm (bidirectional)
 Small dead space < 10ml
 Cleanable and autoclavable
 Very fast update time (0.5ms)
Product Summary
The SFM3300-AW sensor is Sensirion’s digital flow meter
designed for medical applications. It measures the flow rate
of air, oxygen and other non-aggressive gases with
superb accuracy. The special design of the flow channel
results in a very small dead space. Combined with its
ability to withstand autoclave procedures the SFM3300-
AW is extremely suited for proximal flow measurements in
medical ventilation and other respiratory applications.
The SFM3300-AW has been designed with the use by
medical professionals in mind. It features medical cones
for pneumatic connection to standard breathing circuits
and a mechanical interface for easy and reliable
electrical reconnection. The sensor element, signal
processing and digital calibration are on a single microchip
assuring very fast signal processing time, best-in-class
accuracy and superior robustness to rough handling
and adverse conditions.
The well-proven and patented CMOSens^® sensor
technology is perfectly suited for high-quality mass
production and is the ideal choice for demanding and cost-
sensitive OEM applications.
Applications
 Proximal Flow measurement
 Expiratory flow measurement
 For Ventilation & Anesthesia
 Respiratory measurements
 Metabolic Measurements
OEM options
A variety of custom options can be implemented for high-
volume OEM applications (custom flow rates, calibration
for other gases, different body form factor, disposable
option etc.). Contact us for more information.
Sensor chip
The SFM3300-AW flow meter features a fifth-generation
silicon sensor chip. 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. Due to seamless integration of
signal acquisition and processing on the single silicon die
significant performance and cost benefits are achieved.
