0911472255The Eilersen CL series (standard industrial Non-ATEX configurations) and CL-Ex series (intrinsically safe explosion-proof variants accredited under severe ATEX/IECEx directives) represent a premier lineup of digital capacitive compression load cells meticulously engineered in Denmark by Eilersen Electric. Completely bypassing conventional strain-gauge technologies—which are inherently susceptible to micro-structural deformations under excessive stress limits and frequently experience zero-point calibration drifts due to insulation aging—the CL/CL-Ex architecture operates utilizing Eilersen's proprietary patented digital capacitive sensing principle. This mechanism measures minuscule alterations in electrical gap dimensions between internal capacitive plates under compressive loads without demanding substantial physical structural flexing. Consequently, Eilersen CL/CL-Ex load cells possess unmatched mechanical durability, withstand safe overloads up to 1000% of their nominal rated capacity, and exhibit exceptional resistance against extreme side-loads and torsional stresses without sustaining functional hardware damage or calibration inaccuracies.
Regarding hardware architecture, the entire sensor enclosure of the CL/CL-Ex series is precision-machined from a single block of high-purity, heavy-duty stainless steel alloy and hermetically sealed utilizing advanced robotic laser-welding to attain maximum environmental ingress ratings of IP68 and IP69K. The instruments are entirely impervious to water submersion, high-pressure hot steam washdowns, industrial chemical detergents, and processing oils. The core operational distinction between the two model series lies within their approved application atmospheres: the standard CL series is optimized for conventional high-capacity tank, silo, and truck scales; whereas the CL-Ex series features specialized intrinsically safe electronic barriers certified under ATEX/IECEx standards for explosive hazardous atmospheres classified under Zone 1, 2, 21, and 22 guidelines—widely present in petrochemical refineries, paint blending facilities, and manufacturing cleanrooms. Measurement data packages are digitized instantly directly on the internal embedded electronic board and transmitted as high-speed digital signals with extensive internal resolution, achieving 100% immunity against electromagnetic interference (EMI/RFI) emitted by adjacent large industrial motors or variable frequency drives (VFDs). Furthermore, owing to complete pre-calibrated factory metrics, systems incorporating Eilersen CL/CL-Ex load cells operate via an absolute "Plug-and-Play" (Calibration-free) deployment mechanism, allowing maintenance personnel to hot-swap sensors seamlessly on-site without requiring massive physical dead-weights to re-calibrate the entire industrial weighing infrastructure, thereby drastically reducing production downtime and generating superior long-term economic dividends for enterprises.
