9. Working principle：The force surface of the sensor is a 19mm diameter aluminum alloy plate, and a load sensor is connected below the aluminum alloy plate. The force on the aluminum alloy plate is reflected by the load sensor, and the F/S is calculated to determine the stress.

10.Force:Sensors only respond to frontal forces and are not affected by lateral forces.
