CMOSens
Introductory Description
The heart of the CMOSens
powered by Sensirion’s unsurpassed CMOSens
technology. The CMOSens
therefore provides unbeatable performance at very
attractive system cost. One single device covers a range
of 0.05 ln/min up to 200 ln/min .
The CMOSens
integration time of 5ms. This allows correct measurement
and display of fast changing signals. But very often a
precise total flow over a longer period is of higher interest
than a fast single measurement. For this purpose the
CMOSens
read out times (see
Table
slices and recognizes fast signal changes but for the read
out the total flow over the whole period is calculated. The
CMOSens
well suited for difficult measurement conditions when fast
changing gas flows must be monitored and summed up
precisely.
The CMOSens
mass flow independent of the ambient temperature and
pressure changes. You simply connect the gas to be
measured to the CMOSens
instantaneous gas mass flow integral with a selectable
integration time between 5 ms and 640 ms. Depending
on the type a flow range between 0.1 ln/min and up to
200 ln/min can directly be measured by connecting the
CMOSens
In addition to mass flow, the CMOSens
provides information about the temperature on the
CMOSens
temperature data are accessed through an RS232
interface. The RS232 interface allows you to directly
connect the CMOSens
If a special interface such as 4-20 mA current output or
other or another flow range is required, contact Sensirion
for a customer specific solution.

Please contact Sensirion before using any corrosive,
toxic or explosive gas types (see also section 1.6 and
1.7). However, the standard calibration gas is
nitrogen. Please contact Sensirion, if you would like to
use the sensor for applications with other gases.

multi sensor modules and sensor systems. The
unification of semiconductor chip and sensor
technology serves as a platform for highly integrated
system solutions with excellent sensor precision and
reliability. With CMOSens
element forms an integrated whole with a high-end
amplification and A/D converter circuit. Due to the
compact single-chip design, CMOSens
sensors are very resistant to electromagnetic
disturbances (EMC), another important technical
advantage of this state of the art sensor technology.
As a result, CMOSens
offer excellent sensor precision, fast response time
and a very large dynamic measurement range. In
addition, the digital intelligence of the CMOSens
sensor technology enables digital interfaces that
permit an easy link with the system of the customer, a
real advantage and benefit that results in ready-to-use
problem solutions.
