VV1
First Class wind speed sensor
VV1R
First Class Heated wind speed sensor

DESCRIPTION

Sensor "First Class" to measure the wind speed at low power consumption also available in a heated version (model VV1R), compact and sturdy, made of aluminum alloy with anodized to protect against salt air and oxidizing agents. Extremely linear and precise, with high dynamic response even in strong gusts, easy to interface with any data logger. The sensor uses specific arrangements including special self-lubricating bearings, which allow the MeasNet certification and make it ideal for Eolic monitoring applications (Wind power), guaranteeing maximum performance. The sensor is equipped with electrical protections and is available with various signal outputs.

FEATURES

  • Measurement of wind speed with very high precision (<0.1 m/s)
  • Calibrations: wind tunnels MeasNet and ACCREDIA
  • Classification according to IEC 61400-12-1 and "First Class" , Class A 1.96, Class B 3.05 Class S 2:42
  • Instrument according to standard WMO
  • Rotor with high performance ball bearing (MIL-L-6085 C)
  • Low power consumption (<0.1W; <5W@12VDC with heater)
  • Typical measuring range: 0.28 to 50m/s (0 ...150 Hz) up to 100m/s
  • Linearity: R> 0.99998 with a standard error of <0.02 m/s
  • Output signal: pulses (150Hz), 4-20mA, 0÷2Vdc or digital RS485/Modbus
  • Operating conditions: -10 ÷ +70° C, heated version -35 ÷ +70°C, 0 to 100m/s (burst)
  • Power supply: 10 ÷ 30Vdc (<5w 12vdc="" with="" heater="" li="">
