Eilersen / Compression Load Cell DLC (DLC-Ex)

Eilersen / Compression Load Cell DLC (DLC-Ex)

Capacitive load cells with integrated lift-off protection (Patent Pending) for installations e.g. in areas with seismic activity, outdoor silos and high shear mixers. These robust digital compression load cells in EHEDG compliant design are produced in electropolished stainless steel and hermetically sealed to IP68. The load cells type DLC-Ex can be used in ATEX (Ex) and IECEx applications (Zone 1, 2, 21 and 22).

Type:DLC (Non-ATEX) DLC-Ex (ATEX)
Capacity (Emax):50, 100, 150, 250, 500, 1000, 1500, 2000, 3000, 4000, 5000 kg
Accuracy:Industrial 0.10%, Precision 0.05%, High Precision 0.025%
Overload Tolerance:Up to 300% of rated capacity
