Transducer load cells are a critical component in testing and manufacturing airplanes. Because crew and passenger safety in the air is dependent on the integrity of aircraft materials, transducers are widely used to help prevent structural failure. Load cells are also used in the operation of airplanes. They are used to weigh cargo and baggage to prevent overloading of the plane.
Importance of Transducers
Development of new plane models is dependent on data received from transducers. One example of this usage is in testing the strength of wings on Boeing 787 aircraft. In this test, interface load cells are positioned to record the amount of force being applied to a wing. The amount of force is then increased in 10 percent increments until the wing breaks. By using load cells to test and record force, the researchers are able to confirm the accuracy of computer models. Data is then analyzed extensively to create the safest possible airplanes.
Similar testing is carried out on all structural membranes and engines. Because transducer and other load cells can measure minute amounts of force, it is possible to calibrate the breaking point of even tiny components like switches. Larger cells are used to test torque on shafts and engine components. By testing potential materials with load cells, it’s possible to identify the strongest lightweight materials for every application.
Load cells are used for testing shear pins and landing gear functionality. Tire tests that measure the amount of force applied to tires during taking off and landing help insure safe flying. Preventing tire failure during these maneuvers helps manufacturers create safe products and protects the company’s reputation from accidents.
Use of Load Cells in Aviation Industry
Websites like Transducertechniques.com have extensive information about how load cells are used in industry. Since there are several different types of load cells, it is important to purchase the correct type for the intended application. Building a complex machine like an aircraft requires many different types of load cells for testing and during flight.
Airlines use load cells in the operation of aircraft. One application is in the control column or stick that controls the plane’s elevation and direction. Load cells record and display the amount of pressure or force being applied to the stick to move the craft in the desired direction. Control pedals and rudders also use transducers and load cells to help maintain proper position in the air and on land.
The scales used to weigh cargo and baggage use load cells. As the weight of cargo or luggage compresses the scale, it causes a change in resistance within the load cell. The changes are transferred through a wire to a circuit board. The information is then transferred to a readable format, such as a display screen or computer program. Wireless versions of load cells are readily available for many applications.
Load cells are ubiquitous throughout the modern world. Although they are hidden components to most people, they serve a vital function in aircraft technology. From testing to flying, load cells are everywhere.
