SM40A-TY bridge weighing sensor

The SM40A-TY bridge weigh sensor features low installation height, simple and robust structure, and good overload capacity. It uses alloy steel material, has good sealing and waterproof performance, and a unique surface protection process, fully meeting the weighing and force measurement requirements of harsh industrial environments. It has been successfully applied to hopper scales in the chemical and cement industries, factory production line bin weighing, material tank weighing, and tunnel force machine force measurement.

1. Concept

The SM40A-TY bridge-type load cell features low installation height, simple and sturdy structure, and good overload capacity. Using alloy steel material, it boasts good sealing and waterproof performance. Its unique surface protection treatment process fully meets the weighing and force measurement requirements of harsh industrial environments. It has been successfully applied to chemical and cement industry hopper scales, factory production line silo weighing, bin weighing, and tunnel force machine force measurement, etc.


2. Features
