SFM3200-AW Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – Low pressure drop

Preliminary Data Sheet – SFM3200-AW
Digital Flow Meter for medical applications
 Low pressure drop
 Expiratory flow sensor
 Flow range: -100 slm to +250 slm (bi-directional)
 Superior performance at low flows
 Autoclavable & cleanable
Product Summary
The SFM3200-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. A special design of the flow channel results in a
very low pressure drop through the flow body of the
sensor. Combined with its ability to withstand autoclave
procedures, the SFM3200-AW is extremely suited to
expiratory flow measurements in medical ventilation and
other respiratory applications.
The SFM3200 has been designed with the medical
professionals in mind. It features medical cones for
pneumatic connection to standard breathing circuits and a
mechanical interface for an 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
 Ventilation
 Anesthesia
 Respiratory measurements
 Expiratory flow measurement
 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 etc.). Contact us
for more information.
Sensor chip
The SFM3200 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.
