0911472255The Eilersen CH series (heavy-duty standard industrial Non-ATEX configurations) and CH-Ex series (intrinsically safe explosion-proof models certified under rigorous international ATEX/IECEx directives)—encompassing the specialized high-capacity designations CH 100, CH-Ex 100, CH 500, and CH-Ex 500—represent a premier line of high-capacity digital load cells meticulously engineered and constructed in Denmark by Eilersen Electric. Specially designated for the most hostile heavy industrial automation ecosystems, this series stands apart by incorporating Eilersen's proprietary, patented digital capacitive sensing technology. Unlike traditional foil strain-gauge configurations—which rely heavily on substantial mechanical structural flexing of the metal substrate and vulnerable adhesive bonding matrices that are highly prone to insulation fatigue, zero-point calibration shifts, and catastrophic failure under sudden transient shock loads—the Eilersen capacitive architecture measures infinitesimal distance variations between embedded internal dielectric micro-plates without demanding physical structural deformation. This ultra-rigid structural design enables the CH/CH-Ex series to endure extreme mechanical overloads up to 1000% of their rated nominal capacities without experiencing any structural failure or sacrifice in calibration metrics, fully safeguarding heavy tank installations, raw material silos, or steelworks ladle weighing scales from severe physical impacts, dynamic forces, or heavy structural plant vibrations.
Regarding hardware architecture, the entire sensor chassis of the CH/CH-Ex series is precision-machined from a single block of heavy-duty, high-grade stainless steel alloy and hermetically sealed utilizing advanced robotic laser-welding to attain maximum environmental protection ratings of IP68 and IP69K. The instruments are entirely impervious to deep water submersion, high-pressure hot steam clean-in-place (CIP/SIP) washdowns, concentrated acidic chemical atmospheres, industrial processing lubricants, and offshore maritime environments. For explosive atmospheres, the specialized "CH-Ex" variants feature integrated intrinsically safe electronic barriers certified under global ATEX/IECEx standards, qualifying them for safe, continuous operation within hazardous areas classified under Vùng/Zone 1, 2, 21, and 22 directives—widely present in petrochemical refineries, paint blending facilities, chemical manufacturing plants, and agricultural storage facilities prone to explosive organic dust clouds. Measurement data packages are digitized instantly directly on the internal embedded microprocessor board and transmitted as high-speed digital signals with extensive internal resolution, achieving 100% absolute immunity against electromagnetic interference (EMI/RFI) produced by adjacent high-power variable frequency drives (VFDs) or large dynamic industrial motors. Furthermore, owing to complete pre-calibrated factory specifications, systems incorporating Eilersen CH/CH-Ex load cells operate via a true "Plug-and-Play" (Calibration-free) deployment matrix, allowing maintenance personnel to execute quick sensor hot-swapping on-site without requiring massive physical dead-weights to re-calibrate the entire heavy weighing infrastructure, thereby drastically minimizing production line downtime and generating exceptional long-term economic dividends for modern enterprises.
