In an earlier blog post, we discussed the history and growing acceptance of on-board weighing in the United States throughout the years. We stated that weighing hardware components are typically comprised of either load cells (higher accuracy) or secondary type sensors. While secondary sensors have been accepted in recent years to monitor general truck overloads, load cells are making a comeback for many on-board applications.
When the goal is simply to avoid overloading a truck and/or trailer, a lower cost sensor such as an axle transducer, air pressure sensor or inclinometer might do the job. But what about an application where higher accuracy is required?
What is a Load Cell?
A load cell is an electro-mechanical sensor used to measure force or weight. It has a simple yet effective design which relies upon the well-known transference between an applied force, material deformation and the flow of electricity. In other words, they are primary force measurement devices used to create an electrical signal whose magnitude is directly proportional to the force being measured.
They simply are a great tool to obtain accurate weight.
Considering The Need
Years ago, the only on-board scale systems offered in the US trucking market were load cell based systems. Some truck operators began accepting lower cost and less accurate systems designed only to avoid overloading. But, for many applications, the need for high accuracy has never disappeared.
Consider a grapple truck operator that needs to know the weight of each pick-up along his route for reporting purposes. The best method for getting this information is…you guessed it…to install a load cell system.
