It is particularly suited to liquids and gases in fire protection, chemicals, industrial automation, machinery, smelting and hydraulic lubrication.\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.

Connection via screw terminals and one cable entry.\u003c\/p\u003e\u003cp\u003eBody, process connection, connecting rod and paddle in stainless steel, terminal enclosure in stainless steel, weight 0.55 kg. Process connection \u003cstrong\u003eR1\u003c\/strong\u003e taper thread for pipes of DN25 and above. Pressure rating \u003cstrong\u003e16 bar\u003c\/strong\u003e per parameter table, pressure loss 0.08 bar at maximum flow, medium temperature up to 250 °C, ambient \u003cstrong\u003e-25 … +80 °C\u003c\/strong\u003e. A declaration of conformity is not documented in the datasheet. Before sizing, note: As explosion protection the datasheet names only “EX CT4”, without type of protection, gas group or certificate, and T4 does not match 250 °C, so explosion protection is not substantiated. The pressure is 100 bar in the data block and 16 bar in the parameter table. No protection grade is given.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWetted parts and enclosure in stainless steel\u003c\/li\u003e\u003cli\u003eMechanical principle, mechanical and electrical parts separated\u003c\/li\u003e\u003cli\u003eFive paddles supplied\u003c\/li\u003e\u003cli\u003eSetting range 20 … 1800 L\/min by bore and paddle\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\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453617283398,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKN_produkt.webp?v=1790331900","url":"https:\/\/octogon-sensors.com\/en\/products\/qskn-paddle-flow-switch-in-stainless-enclosure","provider":"octogon GmbH","version":"1.0","type":"link"}
