　　Principle of spoke type sensor:

　　Due to its shape resembling a wheel with wheels, we call it a spoke sensor. Due to its low height, it is also known as a low profile sensor. The outstanding advantages of this sensor include low height, high accuracy, good linearity, strong resistance to bias load and lateral force, etc. It can be used to measure pressure and tension, making it particularly suitable for weighing and force measurement

　　Main principles of structural design for spoke type sensors

　　It has 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

　　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 fastening and welding deformation

　　It is insensitive to changes in the position of the applied force and the influence of interference force. The stress distribution in the strain sensitive area of the elastic body only changes with the magnitude of the applied force. The working area of the elastic body has good process performance, including good mechanical processing, bonding, and sealing installation processes. Having a low profile structure, easy installation, good interchangeability, and a low profile structure can enhance resistance to eccentric loads, making the working state stable.

　　Installation method of spoke type sensor

　　Wheel spoke weighing sensors belong to force sensors and are commonly used for static and dynamic measurements. The principle is that the elastic body (elastic element, sensitive beam) undergoes elastic deformation under external force, causing the resistance strain gauge (conversion element) attached to its surface to also deform. After the resistance strain gauge deforms, its resistance value will change (increase or decrease), and then the corresponding measurement shop will convert this resistance into an electrical signal, thus completing the process of converting external force into an electrical signal.

　　The installation method of spoke weighing sensors varies depending on the type of sensor used. Overall, weighing sensors require one location for fixation and one location for force application. To ensure the safety and reliability of the lonely section, and to prevent overloading during the stressed section. After Zui, the wiring method for the spoke weighing sensor is the common four core shielded wire used for weighing sensors. Generally, the excitation power supply voltage is 5-10VDC, with red connected to the positive power supply, black connected to the negative power supply, and green and white connected to the instrument signal. The green signal is positive, the white signal is negative, and there is also a thick wire that is shielded and can be grounded or connected to the casing,

　　The company currently has various types of weighing sensors and force sensors. The main products include 10 series, more than 300 varieties, specifications, ranges, microstructures, tensile and compressive structures, S-shaped structures, spoke structures, column structures, corrugated tube structures, cantilever beam structures, single point structures, box structures, bridge structures, and weighing modules. The weighing range of a single sensor ranges from as small as 50 grams to as large as 3000 tons, and there are analog and digital sensors suitable for various harsh environments such as aluminum alloy, alloy steel, stainless steel, explosion-proof, and high-temperature types. The product is widely used in various fields such as chemical engineering, mining, oil fields, automobiles, lifting machinery, construction, building materials, mechanical processing, thermal power, transportation, etc.
