　　BK-4B-500KG hydraulic press pressure sensor 5kN force sensor

　　Wheel spoke sensors have many characteristics, mainly including the following points:;

　　(I) Has good natural linearity. Because when it is subjected to load, the cross-sectional size of the spokes changes little and can be ignored, which avoids errors caused by size changes. At the same time, due to the use of equal arm full bridge circuits in the bridge, errors caused by asymmetric processing are eliminated.

　　(2) Due to its design based on the principle of shear action, the accuracy of the action point position has little impact on the accuracy of the sensor. (3) It has good symmetry and can withstand large eccentricities and lateral forces.

　　(4) Has a lower height and a flat shape. It deforms less under load, so the interference between the tested structure and the sensor can be ignored.

　　(5) Due to the fact that the sensor is a monolithic structure, the thermal expansion is consistent in all directions, thus achieving good thermal compensation in the full bridge equal arm bridge circuit

　　(6) Strong overload resistance. Due to the high stiffness of the spokes and wheel diagram, when the elastic body is subjected to force, the deflection of the wheel flange is small, resulting in a high overload capacity.

　　(7) It can be designed in both tension and compression dual-use and dual output forms.

　　(8) The measuring range is wide, and it can be used to make force sensors (weighing sensors) ranging from 0.5 to 500 tons. The shortcomings of spoke type sensors are complex structure, difficult processing, and high cost. For this purpose, the cutting principle can be used to design a spoke type sensor with the same external dimensions and accuracy as the spoke type sensor.

　　1、 The principle of a spoke type force sensor is called a spoke type sensor because its shape resembles a wheel with spokes. Because its basic principle is to measure shear stress, it is also called a shear stress sensor. Due to its low height, it is also known as a low profile load cell in foreign countries. The outstanding advantages of this sensor include low height, high accuracy, good linearity, strong resistance to eccentric loads and lateral forces. It can be used to measure both pressure and tension, making it particularly suitable for weighing and force measurement.

　　2、 The main principles of structural design for spoke type force sensors

　　1. It should have good rigidity. In order to maintain the stable working state of the sensor and reduce the influence of external vibration interference, the elastic displacement of the elastic body under load should be reduced as much as possible, so that it has a higher natural frequency.

　　2. There should be a simple and reasonable overall structure. The elastomer should be as a whole as possible, avoiding modular structures. Reduce the impact of factors such as loose fasteners and welding deformation, and facilitate the simplification of processing technology and cost reduction.

　　3. Not sensitive to changes in the position of the applied force and the influence of interference forces. The stress distribution in the strain sensitive zone of elastomers is expected to only vary with the magnitude of the applied force.

　　4. The process performance of the elastomer working area is good, including good mechanical processing, bonding, and sealing installation processes.

　　5. It has a low profile structure, easy installation, and good interchangeability. A low profile structure can enhance the ability to resist lateral forces and stabilize the working state.

　　YOLO-LOADCELL, a brand of Youzhongli, produces weighing sensors and various weighing modules that can be used for single item weighing, ingredient system weighing control, and can output communication and analog signal connection control systems. It has high accuracy (0.05%~0.1%) and good stability (annual stability of 0.03%). Aluminum alloy material, alloy steel material, stainless steel material, explosion-proof type, etc. can be selected according to the on-site environment. Force sensor, used for various small space force measurement, large hydraulic equipment force measurement, tension and pressure calibration measurement, can be matched with various digital displays, tension and pressure controllers, and standard force measuring instruments.
