CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features and advantages of the radiosonde.
Introduction to Vaisala RS92-K and RS92-KL
The Vaisala Radiosonde RS92-K and RS92-KL offer excellent
accuracy in humidity, pressure, and temperature measurement. These
radisondes feature a heated twin humidity sensor, a silicon pressure
sensor, and a small, fast temperature sensor.
The RS92-KL uses Loran-C windfinding. The RS92-K is used for PTU
measurement, and, for example, a radar can be used for windfinding.
The RS92-K and RS92-KL are tuned at the factory to the default
frequency of 403 MHz. The frequency can be adjusted within the
400.15 to 406 MHz telemetry band.
