3.4 Functional description
Analysis of particles in
ambient air
Fine dust measurement devices in the series Fidas 200 are aerosol spec-
trometers certified in accordance with EN16450. These devices continu-
ously analyze fine dust particles from the ambient air and simultaneously
calculate the immission values PM2,5 and PM10, which require monitoring.
The values PM1, PM4, PMtot, the particle number concentration Cn and the
particle size distribution are calculated and recorded. The number of parti-
cles is determined by means of optical light scattering.
Sampling and drying The sampling head Sigma-2 draws in ambient air.
Volume flow rate: approx.0.3m3/h.
The aerosol passes through the sampling tube with drying section IADS and
into the aerosol sensor. The drying section dries the air that was sucked in,
thus preventing distortion of the measurement by any remaining moisture or
mist particles.
Weather data The following weather-related factors have an impact on and control the dry-
ing effect:
• Air temperature
• Air pressure
• Humidity
The weather station measures this data. Additional data can be measured
and taken into consideration with some models:
WS300 WS500 WS600
Air temperature Air temperature Air temperature
Air pressure Air pressure Air pressure
Humidity Humidity Humidity
- Wind direction Wind direction
- Wind speed Wind speed
- - Precipitation
Scattered light analysis The central element of the device is an optical aerosol sensor. Lorenz‐Mie
scattered light analysis of single particles is applied to determine the particle
size. The single particles move through an optically differentiated measure-
ment volume that is homogeneously illuminated with a polychromatic LED
light source. Each particle generates a scattered light impulse that is de-
tected at an angle of 85° to 95° degrees. The particle count is determined
based on the number of scattered light pulses. The level of the measured
scattered light pulse is a measure of the particle diameter.

Data processing The compiled data is processed in the controller and saved. The device can
be integrated into a higher ranking measurement system via the interfaces
(RS-232 and Ethernet).
The measured data can also be transferred via the USB port to an external
data medium. The data can then be analyzed or processed with the external
device. The software PDAnalyze should be used to process the data with an
external device. PDAnalyze is included in delivery.
Firmware The device is operated via a touch screen. The touch screen shows the user
interface of the firmware Fidas. The firmware Fidas runs on the operating
system Windows Embedded for Point of Service (WEPOS).
3.5 Environmental conditions
Environmental conditions affect the functionality of the device.
The following environmental conditions apply for the operation and storage
of the device:
• Temperature range for Fidas 200 and Fidas 200 E:
+5°C to +40°C
Temperature range for Fidas200S:
-20°C to +50°C
• Relative humidity: non-condensing, meaning that moisture in the air is
not permitted to condense as water on or in the device
• Air pressure: atmospheric pressure
Operation and storage under other environmental conditions, for instance in
corrosive or explosive environments, powerful electrical or electromagnetic
fields, areas with ionizing radiation or areas subject to shocks and vibrations
are prohibited.
