ATEX

The Laumas CE41ATEX and CE81ATEX are AISI 304 stainless steel IP67 ATEX-certified equalization junction boxes for use in explosive atmospheres, connecting up to 4 or 8 load cells respectively with M16×1.5 cable glands and 4/6-wire compatibility. They protect load cell signals in gas and dust hazardous areas across a working range of −20°C to +60°C (−4°F to +140°F).

PRODUCT DETAILS

The CE41ATEX and CE81ATEX are ATEX-certified stainless steel equalization junction boxes, purpose-built for weighing systems installed in explosive or flammable atmospheres. Certified to ATEX zones 0, 1, 2 (gas) and 20, 21, 22 (dust) under classifications II 1G Ex ia IIC T4 and II 1D Ex ta IIIC T85°C.

The CE41ATEX accepts up to 4 load cells via 4+1 M16×1.5 cable glands; the CE81ATEX scales to 8 cells with 8+1 M16×1.5 glands. AISI 304 stainless steel construction with IP67 sealing provides full resistance to dust ingress, temporary immersion, corrosive atmospheres, and aggressive washdown. An equalization board with per-cell 20 Ω potentiometers enables on-site signal balancing, and both 4-wire and 6-wire load cell connections are supported.

Most Common Applications: Chemical plant weighing, petroleum and refinery vessel weighing, grain silo and bin systems, pharmaceutical batch weighing, paint and solvent production, any multi-cell scale in a classified hazardous area.
