By integrating weather sensors, data loggers, communication modules, and power systems, AWS can operate around the clock, collecting key weather data such as wind speed, wind direction, temperature, humidity, rainfall, atmospheric pressure & radiation. The data is automatically uploaded to a data center using GSM & remote data display using radio waves for analysis and application.

]]> Wind Speed and Direction Senser https://hssenterprises.lk/product/wind-speed-and-direction-senser/ Wed, 08 Jul 2026 15:40:23 +0000 https://hssenterprises.lk/?post_type=product&p=1230 Wind Direction Sensor; heavy duty design. Special rugged design with improved dynamic features basing on high precision bearings and optimised balancing.

This sensor is designed for the acquisition and electronic transmission of wind direction data. It is suitable for applications in the field of meteorology and environmental monitoring, e. g. for automatic weather stations, at airports, on research vessels, at industrial sites, for mobile measuring systems etc.

The instrument’s rugged construction and its dust- and water repellent surface, as well as the optional high performance heating enable heavy duty applications like wind energy measurement or operation under severe climatic conditions.

Thanks to various outputs and further options there is a wide range of measuring tasks (refer to Varations).

Electrical design and principle of operation
A rotating magnet at the shaft consist of a magnetic north- and south pole, which venerates a rotating field vertical to the shaft. This rotating field will be detected by an encoder chip on a PCB. The chip has 1024 segments. A full turn of the wind vane equals to 360°.

An electronic circuitry provides an analogue data output.

The application range of the series DB-X are the measurements of pressure in
meteorological stations, aviation use and in laboratories.
Depending on the technical requirements and of the needed redundancy the user can
select the specific model of DB-X, namely DB-1 with one, DB-2 with two or DB-3 with
three independent working pressure transducers. The implemented software allows the
convenient calculation and presentation of the measured pressure values according the
specific application, as QNH, QFE, pressure tendence and historical values.

industry and in laboratories. (for aviation use, see model DB-X series.) Beside the display of the local
pressure the QNH value can be indicated by using the front panel-switch.
The display employ a bright 0.56" LED display with a red sunlight readable LED. The intensity of
display can be adjusted from dark room applications up to sunlight readable, making it ideal for
viewing in bright light applications. The used barometric pressure sensor is designed for measurements
that require excellent accuracy, fast dynamic response and long-term stability and reliability. The
barometer is operable in temperatures from -20°C to +50°C. But for using the excellent high accuracy
the ambient temperature should be between +10 and +30°C.
The Model DB278 D is using an extremely accurate and stable transducer which has a long term
stability of less than 0.1 hPa per year. The DB278 D is compared at 16 measuring points with the
Standard Mercury Barometer EB-3 and corrected, which is confirmed by a work certificate. By means
of this procedure the accuracy is +/-0.15 hPa over the total measuring range.
To use DB278 D for a process controlling, there are options as RS 232 and RS 485 interfaces and
analogue outputs 0...10 V and 0/4...20 mA.

Response Time : < 2 s (standard)
Proof Pressure : 1500 hPa
Burst Pressure : 2000 hPa
Long Term Stability : 0.1 hPa / Year
Operating temperature : -20...+50°C, +10 ... +30°C recommended
