{"product_id":"femb-einperl-druckmessumformer","title":"FEMB Bubbling-through pressure transducer","description":"\u003cp\u003eA hose pump builds up a pressure in a bubbling-through tube. At the bevelled end of the tube air escapes as soon as the hydrostatic pressure is reached — density times filling height — and exactly that pressure stands in the tube, where the sensor reads it. The sensor itself never touches the medium, which is the advantage over a diving probe and the reason aggressive and abrasive media are no problem; foaming has no influence either, unlike with ultrasonics, and no connection below the tank is needed. The bubbling point may be up to 50 m away. The transducer gives 4 … 20 mA and 0 … 10 V at once, shows the value on an LCD display with four keys, and carries an RS232 interface; CANopen or Profibus are available as options. Twenty calibration points linearise irregular tank shapes into a volume. The housing is either die-cast aluminium or plastic, both IP65.\u003c\/p\u003e\n\u003ch3\u003eMeasurement and output\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePositive relative pressure, hydrostatic\u003c\/li\u003e\n\u003cli\u003eSensor 0 … 50 … 1000 mbar, five ranges\u003c\/li\u003e\n\u003cli\u003eOutput 4 … 20 mA and 0 … 10 V at once\u003c\/li\u003e\n\u003cli\u003eCombined error ± 1 % of full scale\u003c\/li\u003e\n\u003cli\u003eResolution 12 bit, TC \u0026lt; 50 ppm\/K\u003c\/li\u003e\n\u003cli\u003e20 calibration points for the volume\u003c\/li\u003e\n\u003cli\u003eLCD display and four keys\u003c\/li\u003e\n\u003cli\u003eRS232; CANopen or Profibus optional\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDevice and mounting\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCasing aluminium 160 × 90 × 60 mm, 1.1 kg\u003c\/li\u003e\n\u003cli\u003eOr plastic 162.2 × 92.2 × 60.2 mm, 0.7 kg\u003c\/li\u003e\n\u003cli\u003eProtection class IP65, EMC coating optional\u003c\/li\u003e\n\u003cli\u003ePressure connection for 6 mm plastic tube\u003c\/li\u003e\n\u003cli\u003eTwo cable glands M20 × 1.5, terminals to 2.5 mm²\u003c\/li\u003e\n\u003cli\u003eExternal pump fed with 24 V DC, 250 mA\u003c\/li\u003e\n\u003cli\u003eBubbling point up to 50 m away\u003c\/li\u003e\n\u003cli\u003eOperation −10 … +60 °C, supply 24 V DC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAll technical data, dimensions and available versions are listed in the datasheet for download.\u003c\/p\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57504498680134,"sku":"FEMB","price":1265.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/FEMB_produkt.webp?v=1790930550","url":"https:\/\/octogon.org\/en\/products\/femb-bubbling-through-pressure-transducer","provider":"octogon GmbH","version":"1.0","type":"link"}
