DVE
Encoder Wind Direction sensor 0 ÷ 360°
DVRE
Encoder Heated Wind Direction sensor 0 ÷ 360°

DESCRIPTION

The 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).

FEATURES

  • Magnetic encoder measurement of wind direction, precise and linear

  • Resolution: <0.15°, accuracy: ± 0.3°
  • Sensitivity <0.21 m/s
  • Low power consumption (<0.1 W; <5W@12VDC with heater)
  • High dynamic response to wind
  • Output signal: 0÷2Vdc, 4÷20mA, RS485/Modbus
  • Operating conditions: -10 ÷ +70°C (35 ÷ +70°C heated version), 0÷80m/s (blasts)
  • Power supply: 10 ÷ 30Vdc

ACCESSORIES
