This document is a technical manual for Futek electronic products. It provides detailed information on the features and usage of its product LSM350.
The LSM350 is a compression/tension load cell with a rated output of 1.5 mV/V and a safe overload capacity of 750 % of full scale. It offers high accuracy with non‑linearity, hysteresis, non‑repeatability and creep each limited to 0.1 % of rated output or less. The cell operates from 60 °F to 160 °F (15 °C to 72 °C) and weighs only 3.2 oz.
The wiring code (WC2) uses green and black for excitation (+/–) and white and red for signal (+/–). The device can be powered by up to 18 VDC or VAC, and includes overload protection for parallel‑beam yoke configurations. Calibration accessories and Teflon‑spun cable are available from Futek.
