Inspeed Vortex Sensor

£ 70.00

Rugged wind sensor handles speeds from 5 to over 125 mph. Reed switch/magnet provides one pulse per rotation. Comes with exterior grade wire. It is designed to provide very accuracy at an affordable price - with a sapphire/tungsten carbide bearing system for super low friction and long life.

Supplied without any electronics, the Vortex sensor is ideal for "do-it-yourself" projects of all kinds.

The Vortex Wind Sensor includes the following major items:

  • a high quality 3-cup rotor pressed on a stainless steel shaft
  • a rugged Delrin body with bronze and Rulon bushings
  • a flat aluminum mounting bracket with 2 holes
  • reed switch and magnet providing one pulse per rotation
  • 25 feet of exterior grade wire (more available on request)

Converting pulses to wind speed is simple using the following formula:

2.5 mph per Hz (1 Hz = 1 pulse/second)

The Vortex Wind Sensor has been tested successfully on various electronic devices with over 1,500 feet (500 m) of wire.
