WS-Series Meteorological Sensors

WSseries_w520

The compact meteorogical sensors of Lufft, called the WS-series offer full flexibility to measure all meteorological parameters. Different interfaces are available to convert the measured parameter into a analoque or digital signal. The Standard SDI-12 bus interface allows serial data transfer over two lines to any measurement device compatible.
