Process connection thread G1\/2 … G2 or flange DN15 … DN250 to GB 9119-2000. Pressure grade 1.0 MPa, 1.6 or 2.5 MPa on request. Medium temperature -20 … +80 °C, high-temperature versions up to -40 … +350 °C, ambient -10 … +65 °C. A protection grade is not documented. A declaration of conformity is not documented in the data sheet. Before sizing, note: No protection grade is given in the sheet; it has to be requested. No protocol, baud rate or register map is documented for RS485. The pressure grade is given as 1.0 MPa, while the order code describes the flange version as PN16 with 1.6 MPa.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFlow, pressure and temperature in one device\u003c\/li\u003e\u003cli\u003eNo moving parts\u003c\/li\u003e\u003cli\u003eFor liquids and gases\u003c\/li\u003e\u003cli\u003e1.44\" colour TFT showing all three values at the same time\u003c\/li\u003e\u003cli\u003eEight-digit totalizer in litres\u003c\/li\u003e\u003cli\u003eOne freely settable alarm point each for flow, pressure and temperature\u003c\/li\u003e\u003cli\u003eThree analogue outputs 4 … 20 mA\u003c\/li\u003e\u003cli\u003eNominal sizes DN15 … DN250, thread or flange\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453658046790,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QEKH_produkt.webp?v=1790331840","url":"https:\/\/octogon-sensors.com\/en\/products\/qekh-flow-pressure-and-temperature-sensor","provider":"octogon GmbH","version":"1.0","type":"link"}
