World Leaders in Load Cells and Unique Weighing Assemblies for Silo, Vessel and Process Weighing

Legal for Trade Approved Products

OIML logo

Weighing equipment for use in commercial, legal for trade transactions must be certified by a local or national approving body, according to metrological regulations.  This includes load cells and the associated electronics performing the A/D conversion and display of the weight reading. The metrological regulations applicable to such components ensure that the weight signal or weight reading generated conforms to a common, agreed set of stringent requirements.  Components that are awarded such metrological approval must be subjected to a demanding series of tests and checks before any approval is awarded. 

In much of the world, the local or national approving body is likely to follow the regulations cited by the Organisation Internationale de Métrologie Légale (OIML). In the United States, the local approving body is likely to follow the regulations cited by the National Type Evaluation Program (NTEP).NTEP logo
