Sect. 1.3.1 Part A System installation and start-up1.3 Electrical connection of flow sensors1.3.1 General remarks on signal lines A and B and field current line CProper operation of the equipment is ensured when KROHNE signal lines A and B are used withfoil screen and magnetic shield.• Signal lines must be firmly installed.• Shields are connected via stranded drain wires.• Underwater or underground routing is possible.• Insulating material flame-retardant to IEC 332.1 / VDE 0742.• Low-halogen, unplasticized signal lines which remain flexible at low temperatures.Signal line A (type DS) with double shielding1 Stranded drain wire, 1st shield, 1.5 mm² or AWG 142 Insulation3 Stranded wire 0.5 mm² or AWG 20 (3.1 red/3.2 white)4 Special foil, 1st shield5 Insulation6 Mu-metal foil, 2nd shield7 Stranded drain wire, 2nd shield, 0.5 mm² or AWG 208 Outer sheathSignal line B (type BTS) with triple shielding (bootstrap line)The bootstrap technology always controls the individual shields (3) of the signal converter exactlyto the voltage which is supplied to the signal conductors (5). As this prevents voltage differencesbetween the individual shields (3) and signal conductors (5), no current flows via the linecapacitances between 3 and 5. The line capacitance seems to become ”zero”.This allows greater cable lengths in case the electric conductivity of the liquid to be measured islow.123456789101112Dummy glider wireInsulation (2.1 red/2.2 white)Special foil, 1st shield (3.1/3.2)Insulation (4.1/4.2)Stranded wire 0.5 mm² or AWG 20(5.1 red/5.2 white)Stranded drain wire, 1st shield, 0.5 mm² orAWG 20 (6.1/6.2)Special foil, 2nd shieldStranded drain wire, 2nd shield, 1.5 mm² or AWG 14InsulationMu-metal foil, 3rd shieldStranded drain wire, 3rd shield, 0.5 mm² or AWG 20Outer sheathField current line C1Line 2 x 0.75 mm² (18 AWG) Cu or 2 x (4 x) 1.5 mm² (14 AWG) Cu (Cu = copper cross section)The cross section depends on the required cable length.For max. permissible cable lengths please refer to Section 1.3.4IMPORTANT!For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.Only the EEx flow sensor may be installed in the hazardous area. The EExcertified signal converter must be installed outside the hazardous area!8 IFC 110 F 05/2003
