MEASURING FORCE, STRESS, TORQUE, WORK, MECHANICAL POWER, MECHANICAL EFFICIENCY, OR FLUID PRESSURE (weighing G01G)

Description

G01L covers instruments and methods for quantifying mechanical forces, stresses, torques, and related quantities in physical systems. This subclass encompasses load cells, pressure transducers, dynamometers, strain gauges, and force sensors used across industrial, scientific, and engineering applications. The classification includes devices for measuring static and dynamic mechanical parameters, as well as those determining mechanical work, power output, and efficiency in mechanical systems. Related pressure measurement technologies, particularly for fluids, fall within this scope, while purely electrical power measurement is excluded.
