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!
| SENSOR TYPE | Balanced wind vane connected to an active, non-contact, zero friction Hall Effect sensor |
| SENSOR RANGE | Full 360 degrees , zero deadband |
| ACCURACY/LINEARITY | +/-0.3 to 0.5% of signal range |
