SeeZol Oil Pressure Sensor Installation Guide for Load Moment Indicators & Onboard Weighing Systems
The Load Moment Indicator (LMI, also called a moment limiter) and the Onboard Weighing System are critical devices that keep excavators, loaders, truck cranes and other hydraulic engineering machines operating safely and efficiently. seezol Technology’s measurement principle is to install oil pressure sensors on the hydraulic circuit to capture cylinder working pressure in real time, then convert it — through a calibrated algorithm — into the current load mass and resultant moment, enabling overload warning and limiting.
