The hydraulic load cell uses a conventional piston and cylinder arrangement with the piston placed in a thin elastic diaphragm. The piston doesn't actually come in contact with the load cell. Mechanical stops are placed to prevent overstrain of the diaphragm when the loads exceed a certain limit. The load cell is completely filled with oil.
The construction of the weighbridge is similar to the static track scales with load cells and weighing platform. The rails are applied to the weighing platform and are designed with rail bevelling. Rail switches are integrated into the rails to detect the position of the wagons on the scale.
Two types of loads may result in overweight trucks: divisible and non-divisible. A divisible load is a load which can be easily divided into smaller parts, such as products that are shipped on pallets, automobiles or grains. A non-divisible load is a load which is unable to be divided into smaller parts, like a piece of equipment or a steel beam.
An example of an electrical force gauge is an "electronic scale". One or more electrical load cells (commonly referred to as "weigh bars") are used to support a vertical or horizontal "live load" and are solid-state potentiometers which have variable internal resistance proportional to the load they are subjected to and deflected by.
Weigh-in-motion is a technology that can be used for various private and public purposes (i.e. applications) related to the weights and axle loads of road and rail vehicles. WIM systems are installed on the road or rail track or on a vehicle and measure, store and provide data from the traffic flow and/or the specific vehicle.
A weigh belt. This is typically mounted on a weight transducer which can typically be a strain-gauge load cell or a servo-balance (also known as a force-balance), or sometimes known as a split-beam. Some older machines may pause the weigh bed belt before taking the weight measurement. This may limit line speed and throughput.
A common property-carrying commercial vehicle in the United States is the tractor-trailer, also known as an "18-wheeler" or "semi".. The trucking industry serves the American economy by transporting large quantities of raw materials, works in process, and finished goods over land—typically from manufacturing plants to retail distribution centers.
PrePass is an intelligent transportation system (ITS) that electronically verifies the safety, credentials, and weight of commercial vehicles as they approach participating state highway weigh stations. Because they comply electronically, commercial carriers enrolled in PrePass are authorized to bypass these facilities rather than pull in for ...
