0911472255The Eilersen BM series (standard industrial Non-ATEX versions) and BM-Ex series (intrinsically safe explosion-proof versions conforming to rigorous ATEX directives)—encompassing the specialized capacity variants BM 50, BM 70, and BM 80—represent a premier line of heavy-duty industrial weighing components meticulously engineered for harsh process environments demanding absolute mechanical structural integrity and uncompromised measurement precision. Developed by Eilersen Electric in Denmark, the global vanguard of capacitive electronic weighing systems, the BM/BM-Ex load cell architecture operates utilizing a patented, non-contact digital capacitive sensing mechanism. This cutting-edge engineering milestone completely completely bypasses the deployment of traditional glued foil strain gauges, which are inherently prone to mechanical fatigue, thermal drift, and irreversible zero-point calibration failures when subjected to severe shock overloads. The Eilersen BM capacitive sensors can withstand extreme mechanical overloads up to 1000% of their rated nominal capacities without sustaining internal hardware damage or sacrificing precision metrics.
The crucial distinctions across these specific model variants reside within their designated environmental safety accreditations and mechanical dimensions. While the standard "BM" series (BM 70, BM 80) is heavily implemented across general tough industrial automation frameworks, the "BM-Ex" counterparts (BM-Ex 50, BM-Ex 70, BM-Ex 80) feature state-of-the-art intrinsically safe electronic barriers certified under global ATEX and IECEx standards. This makes them entirely qualified for permanent installation within high-risk explosive environments categorized under hazardous Zone 1, 2, 21, and 22 directives. The entire enclosure of the BM/BM-Ex series is milled from a single block of high-purity, premium-grade stainless steel and hermetically sealed via advanced robotic laser welding, securing supreme environmental ingress ratings of IP68 and IP69K. Consequently, these sensors are completely impervious to corrosive chemical acids, saltwater environments, high-humidity atmospheres, and ultra-high-pressure clean-in-place (CIP) hot steam washdowns. The factory-calibrated digital signal output ensures absolute immunity to electromagnetic interference (EMI/RFI) produced by adjacent heavy-duty variable frequency drives (VFDs) or large industrial motors. Thanks to Eilersen's proprietary "Plug-and-Play" (Calibration-free) technology, deployment and future component hot-swapping can be executed instantly without using massive physical test weights to re-calibrate the entire tank or silo scale network, vastly reducing system overhead cost and operational plant downtime.
