The ED-DVE Encoder Wind Direction sensor for wind direction measure (Gonio-anemometer), is made of materials with high reliability and durability, that maintain for long time the characteristics of sensitivity and precision. The mechanical body shape allows to resist at high wind speed or squalls (up to 300km/h). Using a special magnetic encoder that ensures very high resolution and accuracy by eliminating any mechanical friction in a full operating angle of 360°. The output signal is normalized in voltage or current (4÷20mA or 0÷2Vdc) or digital on RS485/Modbus, available with heater at low power (5W@12Vdc). The sensor is manufactured according to standard WMO (World Meteorological Organization) and to EN 15518- 3:2011 normative.
The measurement principle is a magnetic encoder transducer (Hall effect) with very high accuracy and stability over time, whose sensitivity allows an easy discrimination of tenths od degree of angular displacement. The absence of friction of the vane and the perfect balance, ensures the highest performance. Also available with heater (code DVR) for areas subject to snow or ice with the same performance.
Calibration of the sensor
The static characteristics of the wind direction sensors are detected by a goniometric system and a specific calibration sofware, in order to compare the angle measured by the sensor, with the fixed position of a certificated goniometer. The dynamic characteristic is determined by the speed of response of the sensor, to sudden changes in wind direction and is tested for batch production.
Make sure there are no obstacles to the rotation around the vane. Periodically (once a year), control manually the rotation by checking that there are no delays or jams.
