Load Cells
What You Need to Know About Load Cells
A load cell is an important part of industrial measurement and is a sensor used in various applications. It is designed to measure the force applied to an object and convert that force into electrical signals.
The function of a loadcell is quite simple but of great importance. For example, they are used in industrial weighing systems to accurately measure the weight of products.
They can be used to check the weight of a load on a belt conveyor and to calculate the center of gravity of a boat. The load cell operating principle is usually based on a series of deformation measurements. When load is applied, the resistors inside the load cell undergo deformation. This deformation is detected as a resistance change or a voltage signal and transmitted to the measuring instrument.
The use of load cell is preferred in weight and force measurement.
Load cells come in various shapes and sizes and can operate in different force ranges. They are also designed to be resistant to different environments. A load cell to be used in an industrial environment can be designed to withstand shocks, vibrations and extreme temperature changes.
A load cell sensor is a precision electronic device used to measure the weight or force of an object.
The load cell plays an important role in industrial measurement applications. It must be properly selected and installed to ensure precise and reliable measurements. They also require regular maintenance and calibration. However, when used correctly, a load cell can increase efficiency in industrial processes and significantly reduce operating costs.
How Does a Load Cell Work?
The working principle of a load cell generally relies on a series of deformation measurements and includes the following steps:
- Force Application: The first step is the application of a force to an object, typically involving weighing a load, lifting, or applying force on a machine.
- Deformation: When the force is applied, the load cell induces some deformation in its measuring elements. This deformation is based on the structural properties of the load cell and varies depending on the magnitude of the force.
- Electrical Signal Generation: Deformation causes a change in resistance or strain within the measuring elements of the load cell. This change is perceived as an electrical signal and transmitted to the measuring device.
- Signal Processing: The measuring device processes the electrical signal received from the load cell and converts it into a numerical value, representing the magnitude of the applied force.
- Data Reading and Analysis: Finally, the obtained numerical value is read and analyzed. This analysis is typically used to provide feedback to a control system or inform a user.

What is Load cell Calibration?
Loadcell Calibration is a process performed to ensure that load cells can make accurate and reliable measurements. This calibration process is performed to verify the actual measurement values of the load cell and correct them when necessary.
Load Cell Calibration is the process of making the measurement results given by the load cell accurate and reliable by comparing them with known reference weights. This process is necessary to improve the accuracy and precision of the load cell.
Calibration Process
The load cell calibration process usually includes the following steps:
1. Preparation: The load cell to be calibrated must be cleaned and in an environment suitable for the operating conditions. In addition, the necessary calibration equipment (reference weights, measuring instruments, etc.) should be ready.
2. Use of Reference Weights: A gradual load is applied to the load cell using reference weights with known weights. For example, weights with 0%, 25%, 50%, 50%, 75% and 100% load capacity can be used.
3. Data Collection: The measured values of the load cell for each reference weight are recorded. This data is analyzed by comparing it with the output signal of the load cell.
4. Calculation and Correction: The differences between the measured values and the reference weight values are calculated. These differences are used to make the necessary corrections to improve the accuracy of the load cell.
5. Documentation: The calibration process is documented. This includes the date of calibration of the load cell, the reference weights used, the measurement results and the corrections made.
