　　Wheel spoke sensors are also known as pancake sensors due to their low cross-sectional design and the appearance of pancakes. This type of sensor can withstand tension and pressure and is widely used in measuring applications such as platform scales, car scales, track scales, and tensile testing machines

　　To learn more about the structure of spoke sensors, we should first understand the structure of spoke sensors. As is well known, resistive strain sensors mainly consist of three parts: strain gauges, elastic elements, and measurement circuits. The basic principle of the measurement circuit of the weighing sensor is the same, and small strain gauges do not have a significant impact on the results of the sensor. The reason why there are so many types of weighing sensors is that manufacturers have already modified and designed more reasonable mechanical structures based on the application of the sensors, thus designing elastic elements of different shapes. As a result, the sensors have various shapes, and users have become increasingly easy to use and install weighing sensors.

　　The elastic element of the spoke type sensor is a hole structure elastic element, and its entire structure looks like a wheel, and multiple shear beams with fixed supports on both sides are formed by the hub, spokes, and tire. Elastic element of spoke type sensor

　　The shear force elastic element of the pore structure has a low profile and good stability. It is not very sensitive to bending moments, but has good linearity, high lateral stiffness, and strong resistance to directional and eccentric loads. The overall structure is symmetrical, and the thermal expansion in different directions is consistent with each other, with a small temperature coefficient.

　　The hole shaped elastic element adopts a simple drilling process. In order to ensure that the cross-sectional shear beam has greater stiffness and less stress concentration at the root, and the strain area is in a pure shear stress state, the adhesive position of the resistance strain gauge can be used more reasonably. If there are more holes formed by shearing the strain beam, it is easier to obtain the ideal stress area suitable for pasting resistance strain gauges

　　Advantages and disadvantages of spoke sensors

　　Advantages: Strong impact and offset load resistance, not affected by loading points and support edges, with good linearity, fixed installation, easy installation, and good interchangeability.

　　Disadvantages: Complex mechanical processing, high manufacturing costs, easy to lag and difficult to control

　　However, when choosing a sensor, we should pay more attention to the installation conditions of the sensor under the premise of the same accuracy and range parameters. Below, we will compare the spoke sensor with other weighing sensors to determine whether to choose a spoke sensor
