Application story – written from Teun Mulder (HITMA Instrumentatie B.V.):
At the new university in Amsterdam the Dutch installer Wolter & Dross installed a Priva Building Automation System to control the heating, ventilation, air conditioning and the sunscreens applications. Especially for automatic control of the sunscreens they installed the Lufft compact weather station WS600-UMB. They combined the compact weather station with three external Lux-sensors (with analogue outputs). Therefore, the system includes solar intensity, precipitation, wind direction and wind speed in its automatic control calculation.
Lufft WS600-UMB with 3 Lux-sensors
According to Wolter & Dross, the biggest advantages of the Lufft weather stations are…
» Easy compact installation
» Maintenance free ultrasonic wind meter
» Only 1 surge protection needed (for analogue systems you need to protect at least 20 wires)
» Ventilated temperature and relative humidity measurement
(more accuracy specially during warm days without wind/foggy conditions)
» Heated sensors (Normally only used on very expensive ultrasonic wind meters)
With this building automation solution the University of Amsterdam profits from better power usage with a real long-term profitability.
Hitma-application: Lufft WS600-UMB with 3 Lux-sensors
The Lufft-partner HITMA Instrumentatie B.V. placed also their first WS-600-UMB in combination with 3 sensors connected to a external Modbus-module. In the Netherlands it’s common to use a weather station on each (bigger) building with a Building Automation System. Specially when the building have sunscreens. The temperature and relative humidity measurement is used for controlling the burner, chillers andthe supply air temperature.
