Classic Wind Speed Transmitter
wind speed measurement
The low-inertia light metallic cup star and opto-electronic
pick-up combine to give a starting threshold of only 0.3 m/sec
(0.7 mph). An electronically regulated heating system keeps
the ball bearings and rotating parts frost and ice free down
to -35°C (-31°F). The instrument is rated for 60 m/sec
(135 mph) and 85°C (185°F). The Classic is ideal for
process plants required to measure wind conditions. Standard
analog outputs connect easily to data aquisition systems.
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.
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
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.
