Using A Load Cell For Engineering Decisions

By Adriana Noton


Making a good sound decision in engineering requires having solid data to back it up. Engineering must make a conclusion on designs or products so having that data is crucial to making the right judgment. Using a load cell to support engineering can help you collect the vital data needed to help with this process. As an engineer or technician, you need to know all about this tool and how it works if you will be taking data with it.

This object measures force in two types of forms being tension and compression. The tensile force is the act of pulling an object apart. The force that pushes or compresses an object is called compression. These two forces are measured in units called Newtons or Force Pounds.

The device itself is very rugged, it's built to handle huge forces. These can withstand thousands of pounds or newtons without causing damage to the component. These are used in many applications, even jobs that are pushing and pulling with high strength or load force. The cells are built with high strength steel, so they are both durable and tough.

These devices are very common and can be found in many different measurement machines. A tensile testing machine uses these to measure the force as it compresses or pulls apart various materials. Tensile testing machines are very common to measure the yield strength of any type of material from exotic alloyed metals to simple things like concrete.

One of the reasons why engineers use these devices so much is to help assist the fidelity of computer aided analysis models. Sometimes when the engineer is putting together a simulation model, they have to assume or guess some of the forces acting upon the design or product. This guess can throw off the analysis model and not give good information. The load cell helps feed the force data right directly into the model, giving it high accuracy for the engineers to make a decision or understand what is happening to the design.

Prior to measuring with one of these devices, you need to understand some more information about the cell. Be sure you review which range of force the cell you have is measuring. If the load or force exceeds the upper limit of the instrument, it will start to drift or give false measured data.

If you have a cell that has too high of a range, the force you collect may not even register on the cell. This happens because the force is so small compared to what the device is built for it wont see the load. This is what engineers call collecting data down in the muck, because the cell cant distinguish between the force and white noise coming from the data acquisition system.

Be sure you understand these small points when getting ready to measure a force with one of these items. Using a load cell to support engineering will help correlate the analysis and give more accuracy to the prediction of the models. It is vital that engineers use good solid data to accurately make a sound decision on the product or design they are working on.
