Product Description

WS503 Tiltable pyranometer, wind, temperature, air pressure, relative humidity, electronic compass

Compact all-in-one weather sensor from the WS-Series. Measurement of temperature, relative humidity, air pressure, wind direction, wind speed and radiation.

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.  Comes with 10m cable.

Parameters measured:
  • Temperature, relative humidity, air pressure, wind direction, wind speed, radiation
  • Measurement technology: Ultrasonic/Wind, NTC/T, Capacitive/RH, MEMS capacitive/Pressure, Tiltable Pyranometer Kipp&Zonen/Radiation
  • Product highlights: Compact all-in-one weather sensor, tiltable pyranometer, low power, heater, aspirated radiation shield, maintenance-free operation, open communication protocol
  • Interfaces: RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, XDR and optional SDI-12
Advantages of the Smart Weather Sensor WS503
  • All-in-one housing concept of a compact weather sensor combining 6 measurement parameters in one housing with only one cable connection
  • Tuiltable Kipp & Zonen CMP3 Pyranometer integrated into all in one housing
  •  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
