WS504-UMB Smart Weather Sensor - discontinued
Compact all-in-one weather sensor with measurement of temperature, relative humidity, air pressure, wind direction, wind speed and radiation.
DISCONTINUED
DISCONTINUED
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, air pressure, wind direction, wind speed and radiation. One external temperature or rain sensor is connectable.
IMPORTANT: WS504 is discontinued
- Temperature, relative humidity, air pressure, wind direction, wind speed, radiation
- Ultrasonic/Wind, NTC/T, Capacitive/RH, MEMS capacitive/Pressure, Tiltable Pyranometer Lufft/Radiation
- Wind detection with birdproof construction. Compact all-in-one weather sensor, tiltable pyranometer, low power, heater, aspirated radiation shield, maintenance-free operation, open communication protocol.
- RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, XDR and SDI-12
Advantages of the Smart Weather Sensor WS504
- Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
- All-in-one housing concept of a compact weather sensor combining 6 measurement parameters in one housing with only one cable connection
- Tuiltable pyranometer unit
- Built-in data pre-processing, universal interfaces and selectable output protocols
- Compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol
- Maintenance-free operation – no moving parts that can wear out
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
- Ventilated temperature and humidity measurement according to WMO guidelines
- Integrated heater that can be switched on if there is danger of frost
Examples of use of the Smart Weather Sensor WS504
The robust and maintenance-free smart weather sensor WS504 is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.
Examples of use:
- PV-Monitoring / Solar Monitoring on photovoltaic farms
- Automatic weather station / Automatic weather sensor (AWS)
- Hydro-meteorological stations
