R.M. Young Prop & Vane Wind Sensor

R.M. Young Prop & Vane Wind Sensor



Order

Description

High Performance, Multi-Application Wind Sensor with Rugged, Light Weight, Corrosion-Resistant Construction


Feature

Improved reliability and lower cost thanks to rugged, light weight, sea air and pollutant corrosion-resistant construction

  • Construction of UV stabilized thermoplastic with stainless steel and anodized aluminum fittings
  • Injection-molded helicoid shape propeller
  • Propeller rotation produces AC sine wave voltage signal with frequency directly proportional to wind speed.
  • Slip rings and brushes are eliminated for increased reliability
  • Assures good fidelity in varying wind conditions
  • Vane position sensed by a precision potentiometer located in sealed chamber
  • Known excitation voltage applied to potentiometer element produces voltage directly proportional to azimuth angle.
  • Transient connections & cable terminations are in junction box on mounting post for ease in making sensor cable connections.
  • A 5 conductor cable is required for power and sensor connections.
  • Precision grade stainless steel precision ball bearings
  • Orientation ring for maintaining wind direction reference when the instrument is removed for maintenance
