Table 20 WXT530 operating environment
Property Description/Value
Operating temperature −52 … +60 °C (−60 … +140 °F)
Storage temperature −60 … +70 °C (−76 … +158 °F)
Relative humidity 0 … 100 %RH
Pressure 600 … 1100 hPa
Wind
1)
0 … 60 m/s (0 … 134 mph)
IP rating IP65, with mounting kit: IP66
1) Due to the measurement frequency used in the sonic transducers, RF interference in the
200 ... 400 kHz range can disturb wind measurement.
