Weather sensor WST6000 GTB
The weather sensor WST6000GTB is an essential part of any automated energy saving system dedicated to building automation. This sturdy device measures in a permanent way :
- the wind speed
- the wind direction
- the ambient air temperature
- the atmospheric pressure
- the relative humidity
- solar radiation incident on each facade of the building
- external light intensity
- calculation of dew point
The high precision weather sensor WST6000GTB answers quickly the variations of wind and measures from the slightest breath. The measurements provided by the weather sensor are transmitted by a MODBUS RTU protocol on RS-485.
With four integrated pyranometer, the WST6000GTB provides direct measures of the strength of solar radiation with its angle of incidence on each façade. This ensures an entire consideration of solar energy incident on the building of the summer to the winter solstice. The installation of this compact weather sensor is easy, thanks to the integrated mast adapter for mast Ø 50 mm. The connection is made through an IN/OUT water tight connector.
