Connection via six-core PVC cable Ø 4 mm.\u003c\/p\u003e\n\u003cp\u003ePlastic housing, process connection Rc1\/2, G1\/2, Rc3\/4, G3\/4, G1, R1 or G1-1\/2 by size. Working pressure 0 … 1.0 MPa, pressure resistance 1.5 MPa. Medium and ambient temperature 0 … +50 °C without dew or ice. Protection grade IP40. The EMC standards IEC 61000-6-2 and IEC 61000-6-4 are named; a declaration of conformity is not documented in the datasheet. Before sizing, note: the 3000 and 6000 L\/min sizes appear only in the order code and the dimension drawings, no technical data exist for them. Whether NPN or PNP applies cannot be read unambiguously from the datasheet. The core assignment changes with the output version, so a cable does not fit every version.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour display, turns by 180°\u003c\/li\u003e\n\u003cli\u003eShows instantaneous flow, total and percentage of range\u003c\/li\u003e\n\u003cli\u003eTwo switch outputs with window, differential and cumulative modes\u003c\/li\u003e\n\u003cli\u003eAnalogue 1 … 5 V or 4 … 20 mA, alternatively RS485\u003c\/li\u003e\n\u003cli\u003eRepeatability ± 1 % F.S. ± 1 digit\u003c\/li\u003e\n\u003cli\u003eWorking pressure up to 1.0 MPa, pressure resistance 1.5 MPa\u003c\/li\u003e\n\u003cli\u003eEMC to IEC 61000-6-2 and IEC 61000-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453624099142,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QGKE_produkt.webp?v=1790331840","url":"https:\/\/octogon-sensors.com\/en\/products\/qgke-thermal-gas-flow-sensor-colour-display-ip40","provider":"octogon GmbH","version":"1.0","type":"link"}
