LCZ-303B Bellows Sensor Module

The LCZ-303B corrugated tube weighing sensor module adopts a shear or bending structure, with one end fixed and the other end subjected to force. It has a low operating table, high accuracy, and stable performance. The metal corrugated tube is welded and sealed, and inert gas is filled inside. Strong resistance to overload, fatigue, and unbalanced loads. It can be widely used in specialized scales such as can scales, electronic belt scales, hopper scales, platform scales, various material testing machines, and other force measuring devices.
