WSD-PB Dual Wind Speed/Direction Sensor
WDSM
The Model 034A Wind Sensor combines wind speed and direction measurements into a single remote sensing unit. The 034A Wind Sensor installs in minutes and will provide accurate, long term, continuous monitoring in hostile environments.
  • Wind speed and direction in a single sensor.
  • Durable aluminum and stainless steel construction.
  • Low starting threshold.
  • Stainless steel bearings.
  • Low power.

Operation:
The 034A is designed to operate within a temperature range of -30°C to +70°C and with wind speeds up to 155 mph. Wind speed is measured using a sealed reed switch which provides a series of pulses at a rate proportional to wind speed. Aluminum cups are used for durability. Wind direction is measured using an aluminum vane directly coupled to a precision potentiometer. Variations in wind direction produce a corresponding change of voltage, which lends itself to both digital and analog measurement systems.

Construction:
High quality aluminum and stainless steel components, and high gloss white powder coating insure long life with minimal maintenance. Cable length may extend hundreds of feet without affecting measurement performance.
