ANEMOMETER

This is' my collection of equipment meteorologiche.La Most tools work 24 hours on 24, the remaining part of a small private museum where my house are original instruments dating from 50 and 60 from various parts of the world.

AEROVANE QUALIMETRICS

Until recently it was installed on the truss to the station but then because of that honor and has 'been replaced by a more' modern wind vane of MRI-Young.

It 'a tool unavailable on the market because the model I own and' was produced in 70-80 years and that the American parent is one of the few Europeans and happy owners of this particular airplane.

For all the details I refer you wing special section dedicated to him.

MR YOUNG-WIND VANE

And 'the instrument that has replaced the previous airplane.

This is a modern, lightweight model made entirely of plastic and resin, which ensures speed reading 'by a magnetic pickup system and a classic potentiometer endless race for the leadership.

Observatory and 'connected with a conversion signal to translate the frequency generated by the rotating propeller speed' wind and an analog console.

MECHANICAL ANEMOGRAFO MONTHLY LAMBRECHT 1482

            

This completely mechanical and anemografo 'was produced until the year 1990 by the renowned German company located Lambrecht Gottinghen.E' a tool of independent in the sense that his recordings do not require any power elettrica.E 'features a complex system transducer mechanical linkage that allows the "translation" of the movement produced by wind and subsequent registration on the special paper in advance and 'provided by a manual winding watch with a monthly period.

All mechanisms that comprise it are contained within a metal enclosure in which 'applies to a support (usually a pole) and e' through an inspection hatch frontale.Per what 'regarding its characteristics there' s only be noted that unlike the component direction is recorded instantaneously, rate 'is played on a graph as the value medio.Successivamente with the superposition of a particular "rule" transparent,' can determine the speed 'average wind over a given period . It 'a very valuable tool if only for the fact that not' more 'in production because' supplanted by a semi-electronic and that is still popular stations in operation.

ANEMOMETER SIAP VT 0705B

   

 

This is a 3-cup anemometer type Robinson entirely of aluminum with transduction of the horizontal component of the wind through encoder ottico.In practice rotation of the reel disk drives multihole interposed an optical encoder which provides a frequency signal proportional to speed ' then converted into a current signal 4 to 20 mA.

1458 COMBINED ANEMOMETER LAMBRECHT

It is a leading professional model, manufactured by German Lambrecht horse 80s. Manufactured and up to 90 'was probably the first to adopt a special optical receiver to measure the velocity' of the wind, and an encoder WINKEL with gray code 256 to the component of direction.

Since both Sezon there was no sliding contact such as a voltage source for speed 'and a potentiometer without end for the direction, adjustable minimum value was very low and not exceeding 0.5 m / s.

Remarkable value, considering the generous dimendioni above the reel to 3 cups with 24 cups centimetri.Costruito with anticorrosive aluminum and die counterweight vane turned by hand cost then more than 6 million lira, also because 'although there they were produced different versions and variants, it was a very versatile tool, because 'according to the electronic interfaces to which was attached to allow the needs of far more' complex and diverse.

Versions were produced more 'economical with electric transducer (generator) for speed' and potentiometer classic course performance differed depending on the used electronic content.

Weather 6 possesses two models for the transduction of equal speed 'with various types of interfaces for analog outputs at different ranges and two different control modes' for the direction, as I mentioned before, with endless classic potentiometer and digital encoder.

Both models are equipped with electrical heaters in order to ensure a perfect and smooth sliding bearings under conditions of extreme cold temperatures.

ANEMOMETER Fsg GENERATION

Manufactured by a German company known the FUESS and ' a curious self anemometer generator continua.In current practice requires no external power, but generates a voltage proportional to the speed-power 'of rotation of a unique three-reel type of flexible cups Robinson.I technical data reported mentioning the following values: continuous voltage proportional to speed 'of 3.7 vcc lines up to 500 ohms to 40 m / secTensione constantly proportional speed wing' amounts to 3.4 Vcc lines up and more than 1000 ohms at 40 m / Secine practice simply connect any galvanometer and Taral on a scale from 0 to 40 m / sec at 3.4 or 3.7 volts depending on the distance between receiver and transmitter, and the game and 'Indeed, since the scale and' perfectly lineare.Per that concerns the unusual and indestructible reel, I can say that it 'consists of three chrome steel hemispherical cups, mounted on spring arms of steel, this allows the tool be almost 'insensitive to shock accindentali and small and medium-sized hail.

U.S. MILITARY ANEMOMETER TMQ34

Actually 'is a real portable station with electronic sensors transduction because' only detects mechanical component velocity 'and wind direction, provides data on temperature, humidity,' and the dew point temperature raddreddamento wind.

It 'a combination instrument reserved for the military market statunitense.Non there are business models and especially in Italy and not' reperibile.L 'copy which I have and I' was a gift from a friend because 'according to the rules in force in their country and 'can commercilizzarli even on e-bay type auctions.

ANEMOMETER PORTABLE

They are classics like Robinson anemometers which detect the speed 'with 3 cups and ball of anemometers.

From left, the first and 'an anemometer analog Deut house with double index, according to a wind speed sensor with digital reading and the remaining two instruments ball very similar to those that were once used in marine applications.

This is the same pair (only changes the color) for the truth 'are little known and used, as pretty cheap and imprecise compared to traditional models in pairs.

The operating principle is based on bottom-up driven by a lightweight polystyrene ball perfectly spherical by the pressures exerted by vento.L 'practice air enters through two small holes at the bottom and moves the ball down' a tube of inner diameter just above the bead.
