CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features and advantages of the radiosonde.
Introduction to Vaisala Radiosonde RS41-SG
Vaisala Radiosonde RS41-SG offers 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. Wind data, height and
pressure are derived from Vaisala Radiosonde RS41-SG GPS data
combined with differential corrected GPS data from MW41 ground
station.
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 Ground Check Device RI41
or GC41. To make it easier to check the status of the radiosonde,
Radiosonde RS41-SG has LED light indicators visible on the cover. See
Figure 1 on page 15 for an illustration of RS41 with unwinder.
