This chapter introduces the features and advantages of the radiosonde.
Introduction to Vaisala RS92-SGP
The digital Vaisala Radiosonde RS92-SGP offers excellent data
availability, accuracy of humidity, pressure, temperature, and wind
measurement.
This radiosonde type features a GPS receiver for wind finding. The
RS92-SGP has a silicon pressure sensor, heated twin humidity sensor
and a small, fast temperature sensor. The RS92-SGP features easy
additional sensor capability. The synthesizer-based transmitter is stable
and uses a narrow bandwidth. The RS92-SGP is compliant with the
European ETSI standard for digital radiosondes operating in the 400
MHz band, EN 302 054.
In addition to regular soundings, the RS92-SGP radiosondes can be
used to conduct ozone and radioactivity soundings. When conducting
an ozone sounding, an ozone sensor with an interface unit is connected
to the radiosonde. When conducting a radioactivity sounding, an
integrated interface and radioactivity sensor unit is connected to the
radiosonde. Follow the procedures and guidelines in the relevant User’s
Guides to conduct additional sensor soundings.
The Vaisala Radiosonde RS92-SGP can be used with the Vaisala
Sounding Systems MW32, MW31 and MW21, and the Vaisala
Sounding Systems MW11, MW12, or MW15.
This chapter contains information that is needed to operate this product.
General
It is essential that you carry out the pre-launch steps as instructed and
always in the same way. Follow the instructions in the sections below
and refer to Appendix A on page 49 for proper and safe balloon
preparation.
The workorder for a sounding is as follows:
1.Prepare the balloon and optional sounding accessories.
2.Unpack the radiosonde.
3.Prepare the sounding.
4.Connect the battery.
5.Launch the radiosonde.
6.Monitor the sounding with the sounding system.
When conducting additional sensor soundings (ozone or radioactivity
soundings), follow the procedures and guidelines in the relevant User’s
Guides.
Preparing the Balloon and Optional Sounding
Accessories
The balloon and the optional sounding accessories must be prepared
before connecting the radiosonde battery and thereby activating the
radiosonde. This is necessary because the radiosonde should be
launched within 15 minutes of battery connection.
WARNING
WARNING
Read the safety instructions in Appendix A before proceeding.
Normally the balloon-lifting gas (hydrogen or helium) is supplied in
gas bottles, but hydrogen can also be produced with a hydrogen
generator. Carefully study the operation and safety instructions for the
gas bottle facilities or the hydrogen generator.
Take extreme caution when handling the inflated balloon.
Balloon Preparation
It is recommended that the balloon be prepared in a balloon filling
shed. The balloon filling shed must be well ventilated so that possible
gas leaks do not remain inside the shed, even in situations when there
is no electricity.
Follow these steps to prepare the balloon:
1.Load weights that are needed to obtain the required lift onto the gas
nozzle.
