0911472255The Eilersen BL Series Digital Beam Load Cells (encompassing the standard BL Non-ATEX and the high-end explosion-proof BL-Ex ATEX variations) are meticulously researched, engineered, and manufactured directly in Denmark, representing the absolute pinnacle of modern industrial electronic weighing architectures. Departing fundamentally from conventional strain-gauge load cell principles—which remain highly vulnerable to physical mechanical trauma and signal degradation caused by material fatigue over prolonged runtimes—Eilersen implements a patented non-contact digital capacitive technology. This operational methodology facilitates force registration without direct electrical-mechanical contact inside the measurement chassis, eliminating plastic structural deformation parameters. Consequently, the BL and BL-Ex load cell families achieve extraordinary mechanical resilience, tolerating extreme dynamic overloads of up to 1000% of their nominal rated capacities without sustaining structural damage or zero-point calibration drift (Zero-drift). This standard remains unmatched by any strain-gauge configuration available on the market, making the series the ideal technical choice for severe process networks characterized by sharp kinetic impacts, high-frequency physical vibrations, and intensive mechanical shocks.
The product lineup is strategically segmented into two specialized layouts matching localized facility demands: the standard BL variant intended for deployment in regulated safe areas, and the high-specification BL-Ex variant independently certified to stringent global explosion-proof standards like ATEX and IECEx directives. This authorization ensures uncompromised runtime safety inside hazardous zones (Zones 1, 2, 21, and 22), where combustible gas mixtures, volatile chemical solvents, or fine ignitable powders are present within petrochemical, pharmaceutical, and food processing facilities. The external envelope of the Eilersen BL/BL-Ex load cell is precision-machined from high-grade industrial stainless steel and incorporates advanced hermetic laser welding sealing treatments to secure rigorous IP68 and IP69K ingress ratings. This enables the load cells to seamlessly withstand Clean-in-Place (CIP) high-pressure hot water washdowns using aggressive chemical sanitizers, meeting the most demanding hygiene codes required by food, beverage, and medical cleanrooms. Furthermore, the analog measuring values are digitized directly within the rugged sensor body, permitting lossless data transmission over specialized interconnecting cables extending up to 100 meters without signal attenuation or electromagnetic interference (EMI) degradation. The embedded smart electronics support Plug-and-Play swap outs and feature comprehensive factory digital calibration metrics, enabling rapid, weight-free field balancing routines that cut plant commissioning timelines and optimize systemic operational uptime.
