![]() Load cells are characteristically more robust and can withstand higher loads without being damaged. Load cells are more suitable for applications where high accuracy is required, as they are more sensitive than piezoelectric sensors in detecting smaller changes in force. Piezoelectric sensors are most often used in vibration and pressure tests. This voltage can then be measured and used to calculate the force or weight being measured. The word “piezo” comes from the Greek word for “squeeze” or “press,” which refers to the fact that these materials generate an electric charge when they are squeezed or pressed. When a force is applied to a piezoelectric sensor, it generates a voltage proportional to the amount of force being applied. Piezoelectricity is a property of certain materials that allows them to generate an electric charge in response to applied mechanical stress, such as pressure or vibration. They are made of materials that generate an electric charge in response to mechanical stress, such as pressure or vibration. Piezoelectric sensors work on the principle of piezoelectricity. This change in resistance is then measured and used to calculate the amount of force being applied to the load cell. When a force is applied to the load cell, the metal body deforms slightly, which changes the resistance of the strain gages. The amount of force a load cell is engineered to measure is numerated by the capacity of the model specification and design, such as 50lbf (pounds-force) or 5kN (kilonewton). While both types of sensors are used to measure similar physical quantities, they work on different principles and have distinctive characteristics.īy simple definition, load cells measure the amount of force or weight being applied to them. Load cells and piezoelectric sensors are used in all types of measurement applications.
