Unlike mechanical paddle switches, it picks up very small direction changes quickly and without moving parts. The direction is passed as a potential-free contact to VA 500\/VA 520 consumption sensors or a building management system, and two LEDs show the direction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDetects changes below 0.1 m\/s (referred to 20 °C, 1000 mbar)\u003c\/li\u003e\n\u003cli\u003ePotential-free NC contact, max. 60 VDC, 0.5 A\u003c\/li\u003e\n\u003cli\u003eNo mechanical wear parts\u003c\/li\u003e\n\u003cli\u003eInstallation under pressure\u003c\/li\u003e\n\u003cli\u003eWith two VA 500\/VA 520 sensors, measures inflow and outflow in ring mains\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CS Instruments","offers":[{"title":"Default Title","offer_id":68045932363889,"sku":"VA 409","price":0.0,"currency_code":"AED","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/VA_409.b47c55f9.png?v=1793499073","url":"https:\/\/www.generaltechkuwait.com\/products\/cs-instruments-thermal-flow-direction-switch-va-409","provider":"General Tech Services LLC","version":"1.0","type":"link"}
