LP7151 — Double Ended Beam Load Cell, 10-125 klb
NTEP Class IIIL double ended beam load cell from 10 klb to 125 klb, 3.0 mV/V output, NPT conduit entry and IP67/IP68 sealing for truck scales.
Overview
The LP7151 is a double ended beam load cell for truck scales, weigh bridges and weighing modules, covering 10, 20, 25, 40, 50, 60, 75, 100 and 125 klb. It carries NTEP Class IIIL approval with 10,000 multiple intervals under certificate 26-093, so it is accepted for high resolution truck weighing in the US market. Rated output is 3.0 ± 0.003 mV/V with zero balance of ±1% F.S., combined error of ±0.02% F.S. and non-repeatability of ±0.01% F.S. Creep error is ±0.025% F.S. over 30 minutes, temperature effect on zero is ±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., so a truck rolling onto a deck does not damage the cell. 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. The beam is 7.75 in long at 10 to 25 klb, 10.25 in at 40 to 75 klb and 15.25 in at 100 to 125 klb, with end eyes that take mounting pins. Cable entry uses 1/4-18NPT on the light sizes and 1/2-14NPT on the rest, so standard US conduit fittings screw straight in. A four core cable is supplied at 39 ft or 52 ft, 0.23 in in diameter.Specifications
