Order # 4.3171.30.000, Wind Speed & Direction Transmitters

Base Price $169.00


  • Wind Velocity & Direction
  • Heating built-in for de-icing
  • 4 to 20mA outputs
  • Simple hook-up
  • Good price / performance


  • Our compact wind transmitters have the perfect price performance ratio for most commercial and industrial applications. Their built-in heaters make them serviceable in winter conditions and their standard 4-20mA output signal makes them simple to interface to building control panels or industrial chart recorders.

    Speed transmitter
    The wind velocity is measured by means of a low inertia plastic cup-star whose ball-bearing axis is connected to a slotted disk. This disk is scanned opto-electronically and supplies 11 pulses with every rotation. These pulses are converted in the instrument to 4 ... 20mA.

    Direction transmitter
    The wind direction is measured by means of a low inertia metallic wind vane whose ball-bearing axis is connected to a slotted disk. The code disk is scanned opto-electronically and has been built with a 5 bit Gray Code to give a resolution of 11.25 degrees. This Gray-Code is converted in the instrument to 4 ... 20mA.
