LP7155 — Double Ended Beam Load Cell, 1-125 klb
NTEP Class IIIL double ended beam load cell from 1 klb to 125 klb for small platforms through truck scales, 3.0 mV/V, IP67/IP68.
Overview
The LP7155 is a double ended beam load cell that spans the widest capacity range in the family, from 1 klb up to 125 klb, so a single part number covers everything from a small platform to a highway scale section. Capacities are 1, 2.5, 4, 5, 10, 15, 20, 25, 35, 50, 75, 100 and 125 klb, approved to NTEP Class IIIL with 10,000 multiple intervals under certificate 26-093. Rated output is 3.0 ± 0.003 mV/V, zero balance ±1% F.S., combined error ±0.02% F.S. and non-repeatability ±0.01% F.S. Creep error is ±0.025% F.S. over 30 minutes, temperature effect on zero ±0.036% F.S. per 18 F and on output ±0.027% F.S. per 18 F. The bridge is 700 ±10 ohm input and 702 ±2 ohm output, safe overload is 150% F.S. and destructive load 300% F.S., and excitation is 10-15 V AC/DC recommended with 20 V AC/DC maximum. Construction is alloy steel or stainless steel, sealed to IP67 or IP68. Body length runs 7.50 in at 1 to 5 klb, 8.75 in at 10 to 35 klb, 13.50 in at 50 to 75 klb and 18.50 in at 100 to 125 klb. Cable entry is 1/4-18NPT on the light sizes and 1/2-14NPT above, and the four core cable is 0.20 in or 0.24 in in diameter at 39 ft, 52 ft or 66 ft.Specifications
