40H Hall Effect Anemometer - Connection Diagram

Download pdf (105 KB)

The 40H Anemometer uses a solid state Hall Effect transducer to convert the anemometer rotation into a square wave output. There are three terminals on the 40H indicated on the above drawing. Power must be applied to the 40H via the indicated positive (+) and negative (-) terminals. This voltage must be between 5 and 26 volts (+ 24V nominal). The output is an open collector transistor that when used with a pull-up resistor provides a square wave voltage signal output referenced to negative (-).
