2.1.1 Temperature/Humidity - Galltec/Mela KPC 1/6-ME

Function

Temperature and humidity are not only fundamental, but also crucial parameters,

within the measuring process of the BGC-FTIR-Container. So longterm recordings

outside the BGC-FTIR-Container are done to ﬁnd out possible discrepancies in solar

spectra. Furthermore, these measurements contribute to avoid condensation on the

mirror‘s surface of the solar tracker in case of humidity levels at high ranges.

Figure 2.2 shows the Galltec/Mela KPC 1/6-ME. This compact sensor has a rod-

type design with a high degree of accuracy. It has been especially developed for

meteorological applications and provides with its redundant use maximum reliability

for the system.

The sensor can be exposed to salt mist because of its location close to the sea. Thus,

it is used the version with the ZE21-type sintered high-grade steel ﬁlter in order to

protect the sensing element and to reduce maintenance. Therefore the dynamic

behavior changes as one can see in section 5.1.1 on page 52.

Measuring Principle

To measure temperature, the sensor uses a platin PT100 temperature probe whose

basis is a resistance varying according to its temperature.
