This document is about a sensor called FUTEK LCM325 (L1650)
The Futek LCM325 is a miniature inline threaded load cell designed for both tension and compression measurements. It features a compact form factor with a 3/8‑24 UNF‑2A threaded connection at both ends and a 4‑oz (113 g) stainless‑steel flexure body.
Key performance figures include a rated output of 2 mV/N, safe overload of 150 % of rated output, and temperature compensation of 0.005 % of R.O./°F. The device operates from 60 °F to 160 °F (15 °C to 72 °C) with an extended range down to –45 °F (–42 °C) and up to 200 °F (93 °C). Wiring is provided via a #28 AWG, 4‑conductor spiral‑shielded PVC cable, 10 ft long.
