CO Stainless Steel Column Load Cell
The Laumas CO is a 17-4PH stainless steel column load cell rated at 25,000 kg (55,116 lb) with OIML R60 C4 certification, FM HazLoc approval (on request), and IP68 protection. With combined error ≤ ±0.017% and a wide operating range of −30°C to +65°C, it is engineered for high-accuracy certified weighing in hopper, silo, tank and truck scale applications in various industrial locations.
PRODUCT DETAILS
The CO is a premium 17-4PH stainless steel column load cell engineered for high-accuracy legal-for-trade and hazardous-area industrial weighing at 25,000 kg (55,116 lb) capacity. OIML R60 C4 certification (combined error ≤ ±0.017%) covers the most demanding certified weighing requirements, making CO the choice for high-accuracy certified column weighing in classified industrial environments. IP68 full-immersion sealing and 17-4PH stainless steel construction deliver long-term corrosion resistance in outdoor and washdown-duty industrial installations.
The CO millivolt/volt output connects directly to load cell indicators and amplifiers, and is compatible with 4–20 mA transmitters for PLC and SCADA integration. The KITCO stainless steel mounting accessory (to be ordered separately) provides a self-centering anti-rotation system with upper and lower bases and an O-ring for optimized load transfer and lateral stability. PIACO load distribution plates are available for applications requiring load distribution across an oversized base area. ATEX and IECEx certifications are available on request.
Most Common Applications: Hopper, silo, and tank weighing in , oil and gas, and food processing facilities; certified industrial vessel weighing requiring OIML C4 accuracy; outdoor and washdown-duty industrial compression weighing.
