2.1 Introduction to Vaisala Radiosonde
RS41
Vaisala Radiosonde RS41 oers excellent data availability and accuracy of humidity,
temperature, pressure, and wind measurement. The radiosonde is fast and stable with
individual, SI-standard traceable calibration.
Vaisala Radiosonde RS41 temperature sensor utilizes linear resistive platinum technology.
The small size of the sensor results in low solar radiation error and guarantees fast response.
Robust design, Physical Zero Humidity Check and In-built Functional Temperature Check
ensure reliable performance in every situation. The radiosonde is also easy to use. For
example, there is no need for the user to connect the batteries to the radiosonde to activate
it. The radiosonde is automatically activated when placed on the ground check device. To
make it easier to check the status of the radiosonde, the radiosonde has LED light indicators
visible on the cover.
Radiosonde RS41-D is compliant with the European ETSI standard for radiosondes operating
in the 1680 MHz band, EN 302 054. RS41-D is not dependent on GPS wind
finding and can
be used with Radiotheodolite RT20 systems.
To further improve the design of Radiosonde RS41, the radiosonde now has EPS covers
with plastic fasteners. This makes the radiosonde's look and feel slightly
dierent from
before, but the radiosonde performance is still on the same high level. The plastic covers
have been removed to decrease the total plastic amount of RS41.
