  • Load cell for aircraft weighing system


The pilot must undertake a weight and balance check every time an aircraft weighing system or helicopter is readied for a flight. This method ensures that the aircraft and helicopter fly safely within the manufacturer’s performance envelope. Most aircraft, regardless of size, require new weight and balance information on a frequent basis. Installation or removal of equipment after repairs and alterations, or as part of the aircraft or operator’s maintenance schedule, requires the use of the most correct weight and balance data.

For aircraft applications, load cells are a perfect choice A load cell for aircraft weighing systems is a sensor capable of measuring or detecting push and pull forces. These sensors are usually mounted parallel to the force being applied to an assembly or system. 

Aircraft weighing systems that employ platform scales with load cells are indispensable for maintaining safety, optimizing performance, and conducting various aerospace activities. These measurements assist in ensuring that an aircraft operates within its specified weight limits and maintains proper weight distribution, which is critical for flight safety and efficiency. Platform scales with load cells for aircraft weighing systems are used to weigh aircraft. Typically, the plane is pushed forward until all of the wheels are on the platforms. The overall weight is then calculated as the sum of each platform’s readings. Weigh distribution is calculated using distances and differences between platform readings. The Control Indicator, which measures load data from Load cells, is the most important aspect of the system. Each weighing platform is managed separately and is shown at the appropriate display before displaying the total These force measurements can be useful for a variety of aerospace applications, including research and development, in-flight testing, ground testing, and onboard aircraft measurements.

The advantages of using load cells in aerospace applications Applications of loadcells in aerospace


Load cells are devices that monitor forces and send data in order to ensure the integrity and safety of components , products or complete aircraft weighing system.


When needed, load cells can be manufactured with a long fatigue life. They can be constructed to be durable and dependable. They can often sustain performance after performing over 100 million force/load cycle tests.


Load cells can be built to accommodate a variety of operating variables, which is very beneficial in-flight applications. They can be designed to endure g-forces and vibrations, as well as temperature and humidity variations, chemicals, and even physical impact in the surroundings.


In airplane applications, redundancy is important, and it can be built into the load cell. To sustain the mechanical integrity of the flight control system, a backup mechanism can be included in.


Load cells can be built to adjust for off-center loading, allowing sensors to work and perform even under the most challenging of circumstances. Helicopter lift operations are one such example.


Customized dual-bridge designs provide additional testing versatility by allowing two independent force measurements to be taken from the same load cell.


Load cells are designed to have minimal deflection when fully loaded while maintaining high force sensitivity. While supplying data to the black box and throttle control, very sensitive load cells allow the pilot to maintain direct, active feedback to operate the plane. The sensing element links the pilot's touch to real-time feedback from the plane's controls.


The most significant advantage of load cell technology is versatility. While numerous conventional product designs, unique designs are frequently required for specific uses. Load cells can be produced in a variety of sizes and profiles, with a variety of ranges, and for specific accuracy and sensitivity requirements, depending on the application.

Load cells have a wide range of uses in the aerospace industry. Load cells is used for everything including pre-installation material and component load testing to monitoring and controlling forces while installation, assembly, and operation. Load cells can be used for four main types of applications.


Load cells can be used to test generic components for strength, force endurance, component longevity, and other characteristics. Seat belts, individual connections, aeroplane flaps, and cockpit instrumentation are among the components. A standard load cell design can be used for the majority of component-testing applications.


Load cell for aircraft weighing system can be used to test frame structural integrity, durability, and life cycles in order to validate aircraft designs and ensure that all essential criteria are met.


Load cells can be used to test and monitor structural forces in the aircraft during in-flight testing. Bolts and pins in strategic locations on the plane, for example, can be redesigned, constructed, and calibrated to serve as load cells and ensure structural integrity.


Load cells for aircraft weighing system are used for monitoring flight control systems. This occurs when new aircraft designs and builds have been approved for flight and have passed all relevant tests. On both commercial and military aircraft, load cells can be utilized to monitor flight control systems. Pilot force input is measured by strain gauged load cells on commercial flights, and the data is transferred to the aircraft's Flight Data Recorder, also called as the "black box." Load cells are also used on commercial flights to detect the pilot's touch on the control stick. Strain gauged load cells are significantly customized in military aircraft so that they may be used in difficult applications like in-flight tanker refueling, which exposes the load cell to hard environmental conditions during flight. The load cell is part of a aircraft weighing system that tracks and measures the force applied to the aircraft during refueling.
