Load cell Siemens

Обзор



The SIWAREX WL230 SB-S CA shear beam load cell is made of special nickel-plated steel. The 100 kg and 250 kg load classes are implemented as bending beams.

The WL230 SB-S CA load cells are especially suited for platform scales and container weighers where it is easy to introduce the load into the load cell by means of an adjustable foot. The load cell is available in rated loads from 100 kg to 10 t. This means that scales with multiple weighing ranges can be equipped with a single cell type.

Load cells are legal-for-trade according to OIML R60. They are available in accuracy classes C3, C4 and 5.

Дизайн



The measuring element is a spring body made of special steel. Due to the galvanic coating of nickel and the IP67 degree of protection it is suitable for use in harsh environments.
