Eilersen / Compression Load Cell DMC (DMC-Ex) 150

Eilersen / Compression Load Cell DMC (DMC-Ex) 150

Capacitive load cells with integrated lift-off protection (patented) designed for large capacities such as process weighing in areas with seismic activity and outdoor silos. The robust digital load cells are made of stainless steel and hermetically sealed (IP68) for hygienic installations as well as installations in harsh environments and general process weighing. The load cells are also made in hygienic (aseptic) design according to EHEDG guidelines. Load cell type DMC-Ex can be used in ATEX (Ex) and IECEx applications (zones 1, 2, 21 and 22).

Type:DMC 150 (Non-ATEX) DMC-Ex 150 (ATEX)
Capacity (Emax):30000, 40000, 50000 kg
Accuracy:Industrial 0.10%
Overload Tolerance:Up to 300% of rated capacity
