Introduction to Vaisala Radiosonde RS92-D
The digital Vaisala Radiosonde RS92-D offers excellent accuracy in
humidity, pressure, temperature, and wind measurement.
The radiosonde features digital data transmission, which offers
important advantages over analog data transmission. Data availability
during a sounding is excellent, and telemetry errors are always detected.
The digital transmitter also consumes less power than an analog
transmitter, and more channels are available in the meteorological
frequency band.
The sounding system used with RS92-D reads the calibration
coefficients stored in the radiosonde memory via a cable or telemetry
link. The humidity sensors can be reconditioned to remove any
chemical contaminants to ensure excellent humidity measurement
accuracy.
The RS92-D is compliant with the European ETSI standard for digital
radiosondes operating in the 1680 MHz band, EN 302 054. The
radiosonde transmitter frequency can be set electronically.
