R520S is a large range capacity compression load cell, capacity is from 1t to 470t. It is widely suitable for applica- tions in truck scale and heavy-duty process weighing industry, it is with smooth electro-polished surfaces so that it is easy to be cleaned, and is ideally suited to weighing applications in clean-in-place/sterilize-in-place environments. Full stainless steel constructure, completely hermetically sealed by laser. Also it is designed with mandrel with self-aligning arc point to receive force vertically to ensure the high force accuracy
