Products Description
This wind direction sensor uses a Hall chip as the active element, with a magnet on the shaft that rotates just above it. Unlike resistive type vanes, the Hall chip is 100% contactless, so it will not wear out over time. This also means there is zero resistance to rotation, so sensitivity to changes in wind direction is very high.
The electronic core of the sensor accepts 3 to 5VDC as input, with the output ranging from 5% to 95% of the input - with virtually zero deadband. And since you may want to set the minimum or maximum output at "North", there is a unique locking screw that allows you to stop the magnet and rotate the vane until the output is just right.
The vane is is balanced - which is very important for any installation that may not be 1100% vertical. Unbalanced vanes will rotate to where the center of gravity is lowest - and only the wind can move it away - a balanced vane always points in the proper direction.
Product Features
●Wire length variants to suit different applications
●Non-contacting, zero-friction Hall chip for excellent sensitivity and long life
●Low power to operate
●Adjustable "North" locking feature
●Balanced vane for consistent, accurate readings
Product Specification
