{"product_id":"qskp-inline-paddel-stromungswachter-medienberuhrt-edelstahl","title":"QSKP all-stainless in-line paddle flow switch","description":"\u003cp\u003eThe \u003cstrong\u003eQSKP\u003c\/strong\u003e is a mechanical in-line paddle flow switch with a through-bore body in which body, process connection, connecting rod and paddle are all stainless steel. 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 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 DN15 to DN50 with two paddles A and B each, from \u003cstrong\u003e4.2 … 18 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, numbered 3, 1 and 2 in the wiring diagram.\u003c\/p\u003e\u003cp\u003eAll four wetted parts in stainless steel, 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 … +120 °C, protection \u003cstrong\u003eIP33\u003c\/strong\u003e. A declaration of conformity is not documented in the datasheet. Before sizing, note: For DN15 with paddle A the table gives 4.2 … 18 L\/min, the same as DN20, and this has to be settled with an enquiry for DN15. The IP67 case shown in the photograph has no order field. The medium limit of 90 °C governs, not the higher ambient limit.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eAll wetted parts in stainless steel\u003c\/li\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\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453617348934,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKP_produkt.webp?v=1790331901","url":"https:\/\/octogon-sensors.com\/en\/products\/qskp-all-stainless-in-line-paddle-flow-switch","provider":"octogon GmbH","version":"1.0","type":"link"}
