The Lufft WS500-UMB S85900H Compact Weather Station is a professional all-in-one meteorological sensor combining 2D ultrasonic wind speed and direction, air temperature, relative humidity and barometric pressure in one compact, maintenance-friendly instrument. Wind is measured without moving mechanical components across a 0–75 m/s range, while integrated sensors provide temperature measurement from -50°C to +60°C, relative humidity from 0–100% RH and barometric pressure from 300–1200 hPa. Environmental data is transmitted through a two-wire RS485 interface using Modbus communication, while standardized UMB architecture, integrated 20 VA heating, IP66 protection and a standard connector system simplify installation and integration into automatic weather stations, renewable-energy monitoring systems and remote meteorological networks.
Key Features
- 2D ultrasonic wind measurement
- No moving parts for wind sensing
- Wind speed range: 0–75 m/s
- Wind direction range: 0–359.9°
- Wind direction accuracy: <3° RMSE above 1 m/s
- Barometric pressure: 300–1200 hPa
- Pressure accuracy: ±0.5 hPa
- Temperature: -50°C to +60°C
- Temperature accuracy: ±0.2°C in primary range
- Relative humidity: 0–100% RH
- Humidity accuracy: ±2% RH
- RS485 two-wire half-duplex interface
- Modbus communication
- 20 VA integrated heating
- 12–24 VDC power
- IP66 housing
- 10 m standard cable
Because WS500 combines ultrasonic wind, temperature, humidity and pressure inside a single UMB instrument, a monitoring station can replace several individually mounted sensors and reduce the number of separate cables, mounting brackets and logger interfaces that must be installed and maintained.
