Features of Spoke Type Weighing Sensor
Spoke Design
The sensor's elastic element features a perforated structure, creating an overall wheel-like shape with multiple symmetrically spaced spokes between the hub and tire. This design evenly distributes external loads, effectively reducing measurement errors.
Low Profile
Spoke-type load cells are also known as low-profile or low-profile sensors due to their low height. This design makes them easier to install and use, making them particularly suitable for space-constrained applications.
High Accuracy and Linearity
The sensor offers excellent natural linearity, strong resistance to side loads, high accuracy, a low profile, and easy and stable installation.
High Quality Steel: Load cell sensor is made of high quality steel, strong to mechanical fatigue, good hardness, plating on the to resist
Widely Application:Used in reactors, hot and cold liquid hydraulic presses, electronic universal testing machines, various weighing instruments, etc
Long term stability:Compact structure, high comprehensive precision, long-term stability, Item Type: Load Cell, Range: 0~1000kg
Sensitive & precise:Features high precision, high sensitivity, high stability, and in use, Material: alloy steel / stainless steel, sturdy enough
Type of Spoke Type Weighing Sensor
Standard spoke-type sensors
Consists of a hub, spokes, and tire. The spokes form multiple shear beams with fixed supports on both sides. They offer high linearity, strong resistance to eccentric loads, high accuracy, and stable and easy installation.
Low-profile spoke-type sensors
Featuring a flat design and low height, they are also known as low-profile sensors. While maintaining high accuracy, they save installation space and offer strong resistance to lateral and eccentric loads.
Applications of Spoke Type Weighing Sensor
Industrial Weighing Systems
Used for weighing goods in logistics, warehousing, ports, and other environments to ensure fair transactions.The spoke-type sensor's low-profile design facilitates installation in confined spaces while withstanding dynamic vehicle loads.
01
Force Testing and Materials Testing
Used for tensile strength testing of materials such as metals, plastics, and rubber to evaluate material properties.The spoke-type sensor's bidirectional force-bearing design (compatibility of tension and compression) meets dynamic testing requirements.
02
Logistics and Transportation
Installed at highway toll booths or checkpoints, it quickly detects vehicle axle weight to prevent overload.The sensor's fast response speed makes it suitable for high-speed vehicle traffic.
03
Agriculture and Food Processing
Monitors feed ingredient intake, enabling precise batching and controlling production costs. The sensor's corrosion-resistant design (e.g., nickel plating) adapts to the humid environments of feed mills.
04
Research and Experimentation
Used for tensile, compression, and shear testing of materials in universities and research institutes to obtain stress-strain curves.The sensor's high linearity ensures reliable experimental data.
05
The spoke-type load cell operates based on the resistance strain gauge principle. When an external force is applied to the sensor, the elastic body (elastic element, sensitive beam) deforms, causing the strain gauge (conversion element) attached to its surface to also deform. This deformation of the strain gauge causes its resistance to change (increase or decrease). This change in resistance is then converted into an electrical signal by the corresponding measurement circuit, completing the process of converting the external force into an electrical signal. After amplification and filtering, the electrical signal ensures accuracy and stability. Finally, it is processed and displayed by a data acquisition system to obtain the object's weight information.
Installation Steps of Spoke Type Weighing Sensor
Securing the Sensor
Use high-strength screws to secure the sensor to the base, ensuring the fixed end is secure and that there is no unbalanced load on the load-bearing end.
Leveling: When installing a single sensor, use a spirit level to calibrate the base. When connecting multiple sensors in parallel, ensure all bases are on the same level to avoid uneven load.
Connecting Cables
Use a four-core shielded cable:
Red (Ex+) connects to the positive power supply, black (Ex-) connects to the negative power supply (excitation voltage 5-10VDC).
Green (S+) connects to the positive signal, white (S-) connects to the negative signal.
Ground the shield (thick black wire) at one end (usually at the instrument end). Avoid running it parallel to the power line, maintaining a distance of 50cm or more, or use metal pipe to reduce interference.
Installing the Loading Platform
Mount the loading platform (such as a hopper or tank) at the end of the sensor cantilever and secure it with bolts, ensuring the load direction aligns with the sensor's design (vertical compression). Avoid lateral force: Spoke-type sensors have large lateral stiffness, but they still need to be protected against lateral impact or collision. A limiting device (such as an anti-lateral displacement bolt) can be installed.
Precautions
Overload Protection
Do not exceed 150% of the rated load, as this may cause permanent damage.
Install mechanical stops to prevent overloading and lateral impact.
Corrosion and Moisture Protection
Apply petroleum jelly to protect the sensor's exterior surface. Avoid direct sunlight and sudden temperature fluctuations.
For humid environments, use stainless steel or sealed sensors to prevent moisture from reaching the strain gauge.
Interference Prevention Measures
Avoid placing magnetic objects or devices with strong electromagnetic fields near the sensor.
Regularly inspect the cable for aging and replace damaged shielding wires.
Long-Term Maintenance
Clean the sensor surface regularly to maintain heat dissipation.
Calibrate annually or according to frequency of use to ensure long-term stability.
