NOTES:
– Connection with up to 4 load cells of 350 ohm each.
– The combination of two or more Zener barriers (1) GD [Ex ia] implies that the Atex marking of the barriers assembly must be update to (2) GD [Ex ib], as required by the EN 60079-14 standard.
Available versions:
- KMB4 – Kit of 3 ATEX zener barriers for load cells, in an ABS box. For up to 4 load cells of 350 ohm, for intrinsic protection weighing systems in an hazardous area. Marking of the whole box with three Zener barriers: ATEX II 3(1)G Ex nA [ia Ga] IIC T4 Gc (-20°C ≤ Ta ≤ +40°C) for gas, ATEX II 3(1)D Ex tb [ia Da] IIIC T130°C Dc IP65 (-20°C ≤ Ta ≤ +40°C) for dusts.
- ZBPW – Intrinsic protection Zener barrier for load cell supply, for mounting on DIN bar in a safe area, or in a hazardous-proof case. Marking: ATEX II (1) GD [Ex ia Ga] IIC [Ex ia Da] IIIC.
- ZBSG – Intrinsic protection Zener barrier for load cell signal, for mounting on DIN bar in a safe area, or in a hazardous-proof case. Marking: ATEX II (1) GD [Ex ia Ga] IIC [Ex ia Da] IIIC.
- ZBSN – Intrinsic protection Zener barrier for load cell sense, for mounting on DIN bar in a safe area, or in a hazardous-proof case. Marking: ATEX II (1) GD [Ex ia Ga] IIC [Ex ia Da] IIIC.
