It is particularly suited to liquids and gases in industrial automation, machinery, air compression, refrigeration and air conditioning.\u003c\/p\u003e\u003cp\u003eA magnetic piston on a spring is displaced by the flow, and the magnet closes a reed contact outside the wetted part. Setting range in four order fields: \u003cstrong\u003e0.6 … 8\u003c\/strong\u003e, 1 … 15, 2 … 25 and \u003cstrong\u003e27 … 70 L\/min\u003c\/strong\u003e. Scale on the body \u003cstrong\u003e1 … 13 L\/min\u003c\/strong\u003e, marked H2O 20 °C. Accuracy \u003cstrong\u003e5 % of the total range\u003c\/strong\u003e, hysteresis at least 0.6 L\/min. Output \u003cstrong\u003edry reed contact\u003c\/strong\u003e, normally open, \u003cstrong\u003eone or two switch points\u003c\/strong\u003e, switching capacity 24 V DC \/ 250 V AC, 100 mA.

Process connection female thread G1\/4 to G1. Pressure loss 0.3 bar at 25 L\/min, medium temperature \u003cstrong\u003e≤ 90 °C\u003c\/strong\u003e, protection \u003cstrong\u003eIP67\u003c\/strong\u003e. A declaration of conformity is not documented in the datasheet. Before sizing, note: The parameter table gives 40 L\/min as maximum flow for every model, including the 27 … 70 L\/min range. The scale is valid for water at 20 °C only; for other media the switching point has to be checked against a known flow. The parameter table gives 50 bar for every model; the housing material decides, and the plastic version holds 10 bar.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eScale in L\/min directly on the body\u003c\/li\u003e\u003cli\u003eMechanical principle with reed contact outside the medium\u003c\/li\u003e\u003cli\u003eAccuracy 5 % of the total range\u003c\/li\u003e\u003cli\u003eHousing in POM, aluminium or stainless steel\u003c\/li\u003e\u003cli\u003eOne or two switch points\u003c\/li\u003e\u003cli\u003eSupply 24 V DC or 230 V AC\u003c\/li\u003e\u003cli\u003eFor liquids and gases\u003c\/li\u003e\u003cli\u003eProtection IP67\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453615710534,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKJ_produkt.webp?v=1790331900","url":"https:\/\/octogon-sensors.com\/en\/products\/qskj-piston-flow-switch-with-l-min-scale","provider":"octogon GmbH","version":"1.0","type":"link"}
