{"product_id":"qgkm-messumformer-fur-luftgeschwindigkeit","title":"QGKM air velocity transmitter","description":"\u003cp\u003eThe \u003cstrong\u003eQGKM\u003c\/strong\u003e is an air velocity transmitter with probe; it measures a flow velocity in m\/s, not a flow. It is particularly suited to measuring air velocity, for example in ducts; a volume flow additionally needs the duct cross-section and a profile factor, which the datasheet does not give.\u003c\/p\u003e\n\u003cp\u003ePer datasheet heat dissipation or pitot tube, both principles are named in one sentence. Velocity range \u003cstrong\u003e1, 2, 5, 10, 20, 30, 40 or 50 m\/s\u003c\/strong\u003e.

Probe length 220 mm, below 1500 mm to order, up to 5000 mm as a special length. Ambient temperature -5 … +70 °C, humidity 0 … 90 % RH without condensation. Protection grade, dimensions, mounting, display and wiring diagram are not documented. A declaration of conformity is not documented in the datasheet. Before sizing, note: which measuring principle the device uses, heat dissipation or pitot tube, is not stated. The order code contains only the range, no field for output, probe length or connection. The supply is given as alternating and direct voltage in one entry.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEight ranges from 1 to 50 m\/s\u003c\/li\u003e\n\u003cli\u003eAccuracy ± 0.2 m\/s + 3 % of reading\u003c\/li\u003e\n\u003cli\u003eResolution 0.05 m\/s\u003c\/li\u003e\n\u003cli\u003eOutput 0 … 10 V or 4 … 20 mA\u003c\/li\u003e\n\u003cli\u003eDigital linearisation and temperature compensation\u003c\/li\u003e\n\u003cli\u003eProbe 220 mm standard, special lengths up to 5000 mm\u003c\/li\u003e\n\u003cli\u003eSupply 13 … 24 V AC or DC\u003c\/li\u003e\n\u003cli\u003eCable length up to 300 m with 1.5 mm²\u003c\/li\u003e\n\u003cli\u003eAmbient temperature -5 … +70 °C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453631963462,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QGKM_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qgkm-air-velocity-transmitter","provider":"octogon GmbH","version":"1.0","type":"link"}
