EVANE - Electronic Wind Direction Sensor

Zoom

3 in stock, immediate despatch

This electronic wind vane represents the latest technology in wind sensing: a balanced wind direction vane with a near-zero friction bearing and a high accuracy magnetic angle sensor to provide precision wind direction. Unique locking feature allows you to easily set North regardless of mounting orientation. 0-5V output for easy connection to third party acquisition systems or compatible with the Windworks Data logging system for the PC or MAC

Balanced wind vane connected to an active, non-contact, zero friction Hall Effect sensor
Zero dead band. Many potentiometer wind vanes have a dead spot of several degrees. This device has no dead band at all.
Near-zero friction. Since the magnet is not in contact with the Hall sensor, there is no friction from the sensor.
Full 360 degrees
Virtually infinite life. Unlike potentiometers that wear out, the magnetic Hall sensor is non-contacting and should theoretically last forever.
Output 5% to 95% of input voltage
3 wire flying leads.
Supply voltage 4.5 to 5.5 VDC at 15mA
The E-Vane is provided with an offset aluminum bracket with 2 mounting holes.
The mounting is compatible with Vortex wind speed Sensors (the 2 holes match).
Vane approximately 20cm across

The active element is a sealed Hall effect sensor. Wind direction is provided by a magnet attached to the vane, and which hovers over the sensor. The E-Vane requires an input of 5 VDC and provides an analog output of 0-5VDC.

It represents a number of advantages over potentiometer vanes, including:

    Zero dead band. Many potentiometer wind vanes have a dead spot of several degrees. This device has no dead band at all.
    Near-zero friction. Since the magnet is not in contact with the Hall sensor, there is no friction from the sensor.
    Virtually infinite life. Unlike potentiometers that wear out, the magnetic Hall sensor is non-contacting and should theoretically last forever.

The E-Vane requires 5 volts DC for power. It has three wires: ground, power, and signal.

The Inspeed e-Vane also includes a new locking feature which we should have patented but didn't so we could get it to market sooner. It is a way to lock the sensor so you can twist the vane and set "North" (or zero output) to where-ever you wish. That means that the offset bracket can be pointed in any direction you want, unlike other manufacturers that force you to point the bracket to North so it will read correctly. WIth the e-Vane, just mount the vane, lock the sensor when the software (or your device) says North, twist the vane until it points North, then release the sensor so it is free to rotate. Simple!
