IAN (XPB) AEX & IECEx Exd, Exi INDUSRIAL SWICHES INRODUCION he itn pressure, differentil pressure, temperture, level nd flow switches re designed for use in environments where explosive gses nd dust cn be present (e.g. Gs fields, Oil rigs nd Chemicl plnts etc.) nd hve been AEX nd IECEx certified s detiled overlef. (SIL 2 - IEC61508 proven relibility). hese switches re mnufctured from high qulity csting which offers robust construction nd protection to IP66 for use within hevily polluted industril nd mrine environments. A specil feture of the instruments is the seprtion of the flmeproof nd djustment comprtments llowing for sfe on-site djustment of the set point with power on nd the switch in opertion. he IAN Exd certified switches must be instlled in ccordnce with BS EN 60079-14. he certifiction llows for mounting ginst wll or bulkhed with the mininum flmepth distnces specified not being pplicble. CALIBRAION he design fetures simple form of clibrtion djustment ginst scle plte. his llows users to either order units with specific setting, or stock mid rnge setting nd then djust to suit the ppliction. his cn be set sfely with the switch supply live. On removl of the djustment cover the djusting ring cn be turned with smll ommy br or Allen key. he setting is red from the centre of the red pointer ring ginst the clibrted scle plte. Rottion to the left will increse the set point nd to the right decrese the set point. he djustment mechnism incorportes friction device to ensure set point will not chnge under vibrtion conditions.
