The purposes of load cells, also known load transducers, are to help the user measure the physical quantity or mass, and to convert force or energy into another form (ex. force, light, torque, motion, etc.).
How to choose a load cell 1. Consider the load input direction. 2. Consider the object to be weighed: capacity, resolution, shape. 3. Consider the environment the Load Cell will operate in. 4. Consider the desired accuracy, error ratings, and ease of calibration. 5. Select the load cell type for the application.
Load cells have a specified load direction, do not apply side forces, bending or torsional movements on load cells. Inappropriate loading applications will risk reducing the life of load cells, plus distortion of correct measurement results.
