The SA 209 diameter is 130 mm.\u003c\/p\u003e\n\u003cp\u003eThe purpose of the windscreen is to attenuate the wind noise during outdoor measurements. Downwind propagation conditions for the noise measurement method specified in ISO 9613-2 and ISO 1996-2 take into account the wind speed between approximately 1 m\/s and 5 m\/s, measured at a height of 3 m to 11 m above the ground.\u003c\/p\u003e\n\u003cp\u003eMost of the outdoor measurement techniques follow ISO recommendations therefore the noise measurements are carried out in conditions up to the wind speed of 5 m\/s.  The higher readings of the wind speed are often measured at wind farms, as mentioned in the IEC 61400 standard, which for this purpose recommends the use of windscreens with a diameter at least of 90 mm.\u003c\/p\u003e\n\u003cp\u003eThe windscreen plays an important role in outdoor noise measurements, therefore it should be examined regularly and replaced in case of any surface damage.\u003c\/p\u003e\n\u003cp\u003eWindscreen (130 mm) for SV 200 and SA 27x\u003c\/p\u003e\n\u003c!----\u003e","brand":"Svantek","offers":[{"title":"Default Title","offer_id":54502057345357,"sku":"SA 209","price":640.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9344\/9805\/files\/SvantekSA209Picture1.webp?v=1786538199","url":"https:\/\/gomeasure.dk\/products\/svantek-sa-209-windscreen-130-mm","provider":"GOmeasure.dk","version":"1.0","type":"link"}
