The Omega LC307-5K is a miniature high-capacity top-hat compression load cell rated for 5,000 lb (22.2 kN). It uses an all stainless steel body with high-performance strain gages for superior linearity and stability, delivering a 1.75 mV/V nominal output at 5 Vdc excitation with 0.75% FS BFSL accuracy. Temperature compensation is handled by a miniature circuit board built into the 1.5 m (5 ft) cable, keeping the cell accurate across a compensated range of 16 to 71 C (60 to 160 F). Designed to mount on a smooth, flat surface, it suits applications where space is tight but high-capacity loads must be measured precisely.
