Pressure sensor for use on extension plate of auto-weighing truck, is used for positioning extension plate between loading section and frame of truck so that deformation or compression caused by load weight can be measured

摘要

The pressure sensor has a cylindrical sensor unit having a bottom face set with respect to the extension plate, and an upper face provided with a protective lamina and formed with a circular groove. A circular plate is inserted into the circular groove and fixed on a base whose top face is inclined and fixed to the frame of a truck. The pressure sensor is used for positioning the extension plate between the loading section and frame of the truck, such that the extension plate measures the deformation or compression caused by the weight of the load in the loading section of the truck. The measurement results are transmitted to a viewfinder used in determining the weight and amount of load of the truck.
