The economical model for acquisition of meteorological measuring data in theWSC11

• Building technology
• Building automation
• Greenhouse control

• integrable into existing control systems
• with digital interface
• precise and reliable
• wear-free
• easy installation

The weather station compact WSC11 was designed for the varied requirements of the building control technology.
The instrument combines precision of the measuring value acquisition with a very compact construction. A smooth integration into new as well as in existing installations is guaranteed.
The acquisition of a total of 11 meteorological parameters on a minimum space characterizes this device. The wind measurement occurs without moving parts. The thermal anemometer measures wind velocity and wind direction without mechanical wear. A costly maintenance is not necessary.
The integrated GPS module receives automatically date, time, station height, and the geographic position. A manual setting of time is not necessary. The WSC11 determines the azimuth and the elevation of the sun position from the GPS parameters. The reduced air pressure is calculated by means of the altitude above sea level, and the measured air pressure. All parameters are output with the data telegram.
The WSC 11 is mounted on a mast or, by means of a wall holder, directly at the building.
