Characteristics and application of cantilever beam weighing sensor
Cantilever beam weighing sensor, also known as shear beam weighing sensor, is mostly rectangular in shape, and the strain zone is in the middle of the sensor. Cantilever beam weighing sensor has the characteristics of simple structure, convenient installation, reliable use, long service life and high cost performance. Generally, there are two fixing holes at the tail end and a pressure-bearing accessory at the front end, so that it can bear the weight well.
Shear beam load cells are widely used in various fields due to their precision and versatility. These sensors are essential in both industrial and scientific applications where accurate weight and force measurements are critical. By understanding the characteristics and applications of cantilever beam weighing sensors, engineers and researchers can effectively utilize them in their respective fields.
Cantilever beam weighing sensors typically consist of a beam fixed at one end and free at the other. The material of the beam is usually metal, such as aluminum or steel, due to their high strength and resistance to deformation. The design may vary, but common shapes include rectangular and I-beam cross-sections, chosen for their optimal distribution of stress and strain.The advantages of cantilever beam weighing sensor are mainly reflected in the convenience of installation, and the two installation holes can be easily fixed on the base or the platform. Convenient maintenance and replacement. Its anti-bias ability is also outstanding among many types of sensors, and its pressure-bearing accessory has a universal joint, which can accurately adjust the force in all directions.
The performance of a Shear beam load cell is defined by its sensitivity, accuracy, range, and linearity. Sensitivity refers to the sensor's ability to detect small changes in force, while accuracy denotes how close the measured value is to the actual force. The range of the sensor defines the maximum load it can measure, and linearity indicates the proportionality of output to applied force.
Shear beam load cells operate based on the principle of deflection under load. When a force is applied to the free end of the beam, it causes the beam to bend. This bending is measured using strain gauges attached to the beam. Strain gauges are resistive elements that change resistance in response to deformation. The change in resistance is proportional to the force applied, and this change is converted into an electrical signal, which is processed to determine the applied force.
With the rapid development of modern economy, cantilever load cells are widely used in all walks of life. The following are some application fields of cantilever load cells:
