A load cell works on the principle of strain gauge. When a force is applied to the load cell, it causes deformation in its internal structure. This deformation results in a change in the electrical resistance of the strain gauges attached to the load cell. This change in resistance is proportional to the applied force, and this information is converted into an electrical signal by the load cell's circuitry.
Application range of load cell:
Load cells are widely used in various industries such as aviation, automotive, construction, medical, and manufacturing. Some of the common applications of load cells are:
1. Industrial weighing systems: Load cells are used in weights and scales to measure the weight of different products, materials, and commodities.
2. Force and torque measurement: Load cells are used to measure the force or torque applied on different objects or machines.
3. Tension and compression measurement: Load cells are used to measure the tension or compression in different structures and components.
4. Pressure measurement: Load cells are used in hydraulic and pneumatic systems to measure the pressure of fluids.
5. Material testing: Load cells are used in material testing machines to test the strength and durability of different materials.
6. Robotics and automation: Load cells are used in robotic and automation systems to measure the force and motion of different parts and components.
