{"product_id":"qsko-inline-paddel-stromungswachter-paddel-messing","title":"QSKO in-line paddle flow switch, brass paddle","description":"\u003cp\u003eThe \u003cstrong\u003eQSKO\u003c\/strong\u003e is a mechanical in-line paddle flow switch with a through-bore body for sizes DN15 to DN50. It is particularly suited to liquids and gases in industrial automation, machinery, air compression, refrigeration and air conditioning in pipes up to 50 mm.\u003c\/p\u003e\u003cp\u003eA spring-loaded paddle sits in the through bore; the flow deflects it and a linkage operates a microswitch. Setting range fixed by the model, twelve models from six bores with two paddles A and B each, from \u003cstrong\u003e1.5 … 10 L\/min\u003c\/strong\u003e to \u003cstrong\u003e50 … 150 L\/min\u003c\/strong\u003e, fine setting by a knob. Repeatability \u003cstrong\u003e± 2.5 of the total range\u003c\/strong\u003e, without a per cent sign in the datasheet; an accuracy is not documented; hysteresis 2 … 8 L\/min by model, measured with water at 20 °C. Output \u003cstrong\u003emicroswitch, normally open and normally closed\u003c\/strong\u003e, switching capacity \u003cstrong\u003e250 V AC, 3 A\u003c\/strong\u003e. Connection via screw terminals.\u003c\/p\u003e\u003cp\u003eBody stainless steel, process connection, connecting rod and paddle brass, seal NBR, outer housing ABS. Process connection female thread \u003cstrong\u003eR1\/2, R3\/4, R1, R1¼, R1½ or R2\u003c\/strong\u003e at both ends. Pressure rating \u003cstrong\u003e16 bar\u003c\/strong\u003e, medium temperature \u003cstrong\u003e90 °C\u003c\/strong\u003e, ambient -25 … +85 °C, protection \u003cstrong\u003eIP33\u003c\/strong\u003e. A declaration of conformity is not documented in the datasheet. Before sizing, note: The IP67 case shown in the photograph has no order field. Three of the four wetted parts are brass, which with the stainless body forms a galvanic cell in conductive water.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eTwelve models from DN15 to DN50\u003c\/li\u003e\u003cli\u003eSwitching point set by a knob\u003c\/li\u003e\u003cli\u003eHysteresis documented for every model\u003c\/li\u003e\u003cli\u003eSPDT contact 250 V AC, 3 A\u003c\/li\u003e\u003cli\u003eMechanical and electrical parts completely separated\u003c\/li\u003e\u003cli\u003eFour mounting positions permitted\u003c\/li\u003e\u003cli\u003eSame female thread at both ends\u003c\/li\u003e\u003cli\u003eFactory setting to the wanted switching value offered\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453617316166,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKO_produkt.webp?v=1790331900","url":"https:\/\/octogon-sensors.com\/en\/products\/qsko-in-line-paddle-flow-switch-brass-paddle","provider":"octogon GmbH","version":"1.0","type":"link"}
