The Sensors - Test Series
It is a basic need to test the sensors for their functional capability and accuracy in
advance. This is also meant to prevent possible differences in readings due to the
redundant sensor principle.
The following sections will give an overview of the sensors which have been properly
tested. Some of the sensors measuring temperature, humidity and pressure have
been tested in the climate and pressure chamber at the Max Planck Institute for
Biogeochemie Jena. Wind speed was tested in the air duct of the University of
Applied Science Jena. The sensors which are not enumerated were just tested for
their operability.
5.1 Climate and Pressure Chamber
5.1.1 Temperature/Humidity - Galltec/Mela KPC 1/6-ME
The compact sensor KPC 1/6-ME has been testet for his operability, accuracy and
dynamic behavior in comparisson to a reference device. Additionally booth sensors
were compared in order to determine possible differences in the measurement re-
sult. Therefor readings in temperature and relative humidity varying according to
a programmable logic control were done.
Temperature and Humidity Mesurement as a Function of Time
The base for further interpretations are the time responsed measurements. Figure
