WB39.5 Load Cells

The WB SERIES Load Cells have been specifically designed to operate in critical conditions and aggressive environments.


Reliability, low cost, easy of installation and availability of various accessories make them the most used in mobile applications and in the weighing of silos, tanks, platforms, cages, etc.
The high degree of ruggedness and excellent resistance to lateral loads also recommend its use in applications where strong vibrations and lateral thrusts are present.
