Bridge Sensor/SM40A Bridge Load Cell
Product Categories Bridge Sensors
The SM40-A weighing sensor, with its unique bridge-type structure with support at both ends and force in the middle, has enabled large-tonnage sensors to enter the field of high-precision and high-reliability measurement. The sensor force transmission component adopts a pressure head and steel ball structure, which can automatically reset and adjust the center. It has a low profile, a stable structure, a strong overload capacity, good resistance to eccentric force and lateral force, and good dynamic performance, so it can obtain higher measurement accuracy. It is equipped with a lightning protection device and has a good moisture-proof seal to adapt to harsh working environments. It can be widely used in electronic track scales, shallow pit or non-pit-based electronic truck scales, overhead crane scales, and various electronic ground scales and other force measurement and weighing systems.
