{"product_id":"qskl-paddel-stromungswachter-anschluss-messing","title":"QSKL paddle flow switch, brass connection","description":"\u003cp\u003eThe \u003cstrong\u003eQSKL\u003c\/strong\u003e is a mechanical screw-in paddle flow switch for pipes from DN25 to DN150. It is particularly suited to liquids and gases in industrial automation, machinery, air compression, refrigeration and air conditioning.\u003c\/p\u003e\u003cp\u003eA spring-loaded paddle (baffle) stands across the pipe; the flow deflects it and a linkage operates a microswitch. Setting range across the product \u003cstrong\u003e20 … 1800 L\/min\u003c\/strong\u003e, set by the pipe bore and the paddle fitted. Five paddles (31 … 132 mm long) are supplied. Repeatability \u003cstrong\u003e± 2.5 % of the total range\u003c\/strong\u003e; an accuracy is not documented; hysteresis 8 … 80 L\/min by bore and paddle.

Pressure rating \u003cstrong\u003e16 bar\u003c\/strong\u003e, pressure loss 0.08 bar at maximum flow, medium temperature \u003cstrong\u003e90 °C\u003c\/strong\u003e, ambient -25 … +80 °C, protection \u003cstrong\u003eIP33\u003c\/strong\u003e, IP67 with the optional case. A declaration of conformity is not documented in the datasheet. Before sizing, note: As supplied the switch is only IP33, and the IP67 case is needed for outdoor or washdown duty. Stainless steel and brass in the same wetted path form a galvanic cell in conductive water. The data block (90 °C) and the rating plate (120 °C) give different temperatures.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMechanical principle, mechanical and electrical parts separated\u003c\/li\u003e\u003cli\u003eFive paddles supplied\u003c\/li\u003e\u003cli\u003eOne device for pipes from DN25 to DN150\u003c\/li\u003e\u003cli\u003eRepeatability ± 2.5 % of the total range\u003c\/li\u003e\u003cli\u003eSPDT contact 250 V AC, 3 A\u003c\/li\u003e\u003cli\u003eLow pressure loss 0.08 bar\u003c\/li\u003e\u003cli\u003eFactory setting to the wanted switching value offered\u003c\/li\u003e\u003cli\u003eOptional IP67 protective case\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453615776070,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKL_produkt.webp?v=1790331901","url":"https:\/\/octogon-sensors.com\/en\/products\/qskl-paddle-flow-switch-brass-connection","provider":"octogon GmbH","version":"1.0","type":"link"}
