1: The cantilever beam weighing sensor is also known as the shear beam weighing sensor, most of its shape is cuboid, and the strain zone is in the middle of the sensor. Generally, there are two fixed holes at the end and a pressure attachment at the front end to make it able to carry weight well.
2: Cantilever beam weighing sensor is widely used in small weighbridge and platform scale, generally using three sensors or four sensors as a group. Through the signal and conditioner, the signal of multiple sensors is processed and then transmitted to the measuring instrument, so as to display the measurement value.
3: The advantages of the cantilever beam weighing sensor are mainly reflected in the convenience of installation, and the two mounting holes can be easily fixed on the base or the weighing table surface. Easy maintenance and replacement. Its anti-biased load ability also has a prominent performance in many types of sensors, and its pressure attachment has a universal joint, which can accurately force in all directions
4: Simple structure and function of cantilever load cell. Among them, the classical numerical measurement unit not only extracts the sensing signal, but also performs numerical preprocessing, such as filtering and restoring the signal. Symbol generation and processing unit is the core part of the cantilever load cell. It uses the existing knowledge or experience (usually stored in the knowledge base) to further process the recovered sensing signal and get the description information of simulated human natural language symbols in line with the objective object.
Cantilever load cell structure:The general installation method of the cantilever beam weighing sensor is to fix the end of the sensor out of the wire directly on the device through the screw, and the other end is used to force, and press down. Note that when the cantilever beam sensor is installed, the middle part needs to be suspended, and the two ends are fixed and the other end is stressed. Some of the cantilever beam load sensors are made of aluminum, the design of the loading device and installation should ensure that the loading force of the load sensor axis overlap, so that the influence of the tilt load and the eccentric load is reduced to quite small. Cantilever beam type steel weighing sensor, one end fixed, one end loaded, adopts steel ball force transmission, upper and lower pressure head bearing or double ball head structure, with a good sealing structure. Good automatic aligning after loading, easy installation, convenient use, good interchangeability.
The cantilever beam sensor is a kind of structure widely used in weighing instruments. The lower surface of the cantilever beam in the cantilever sensor is provided with a trapezoidal step with a height of about 6mm, the trapezoidal step fixed on the measuring base constitutes a fixed part, and the part suspended above the measuring base constitutes an elastic deformation part, and the inner arm of the cantilever beam is also provided with a strain resistance and a measurement signal generation component electrically connected with the strain resistance. In the process of use, when the cantilever beam bears a certain load, the cantilever beam takes its fixed end as the fulcrum to undergo elastic deformation and bend, and the strain resistance sheet also produces corresponding deformation, and the shape variable is read out or displayed by the measurement signal generator component.
