Other Sensors / SM20 Bellows Load Cell
Product Categories Other Sensors
The SM20 weighing sensor has a low profile, small size and light weight. The outer cover is sealed with a stainless steel bellows, and the performance is sensitive and reliable; the influence of eccentricity and lateral force is small, the dynamic response is good, and the measurement accuracy is high. It is suitable for measurement occasions with small loads. At the same time, it is easy to install, has a strong overload capacity, and is not easy to damage. It is suitable for use in high-precision measurement occasions such as belt scales and crane scales.
