Inspeed’s “WS2R” Reed Switch Wind Speed Sensor – Anemometer

Inspeed’s rugged and affordable WS2 Anemometer is a high quality, Inspeed-designed, Made In America wind speed sensor a variety of options available so it will be sure to be a great fit for your application.  These options include:

  • Sensor type:  reed switch or non-contacting “infinite life” Hall chip
  • Mounting:  vertical bracket or 1/2″ tube mount
  • Rotor:  polycarbonate or metal
  • Wire length:  standard lengths or customized for you

The WS2 wind speed sensor uses either a zero power reed switch (WS2R) or a Hall chip (WS2H) as the active element, with a magnet on the shaft that causes one pulse per rotation.  (If you want 2 pulses per rotation we can do that too – let us know). The conversion factor from pulse rate to wind speed is in the specifications below.  This “WS2R” page is for the Reed Switch Version.  Visit the “WS2H” Hall Sensor page for the Hall sensor anemometer.

The difference between the two is as follows:

  • Power required:  Reed Switch:  0.  Hall Chip:  ~3mA
  • Life:  Reed switch:  depends on voltage/current applied (lower=longer).
    Hall chip:  basically infinite
    NOTE:  both the reed switch and Hall PCB are replaceable items

Battery-powered applications might be better off with a reed switch anemometer whereas the Hall chip might be a better choice for situations where power is available.

The base product has 25′ of wire for the reed switch, but we offer standard options for 50′, 100′, and 200′ feet.  If you need more, or less – reach out to us – we can do up to 1,000′ or more!

The shaft has a Tungsten Carbide ball pressed into the end, which rides on a small sapphire.  The result is very low friction – for low wind speed sensitivity, and basically zero wear – for long life.

The polycarbonate rotor is designed by Inspeed based on years of experience with some tough users (mainly storm chasers!). It is light and strong – to give you years of dependable service.  If you prefer a metal rotor, we can do that too.

The mounting bracket can be attached to just about anything so it is easy to get up and running.  the single-screw mount to the head means that you can pivot the head relative to the bracket if you need to make fine adjustments to make the rotor completely level.  Alternatively we offer a tube mount base so it can be mounted to a 1/2″ tube (available separately from Inspeed or customer-provided).

The Inspeed WS2R anemometer is based on simplicity, ruggedness, and a commitment to precision and accuracy.
