Selection of Weighing Sensors for Electronic Belt Scales

Electronic belt scales play a crucial role in modern industry, widely applied in the automatic weighing and metering of bulk materials. With the development of production and enterprise management, the requirements for their accuracy and stability have also increased. As the core component of an electronic belt scale, the weighing sensor directly provides the detected weight data, making the selection of a high-quality, high-performance sensor particularly critical.

When selecting a weighing sensor for an electronic belt scale, it is essential to first clarify the factors that influence this choice. The main factors affecting the selection include the working environment of the sensor, the number of sensors configured on the scale frame, and the weight range of the materials conveyed by the conveyor.

Factors Influencing the Selection of Weighing Sensors in the Working Environment:

1. High Temperature: High temperatures in the environment may cause the coating film on the sensor's surface to melt and alter the stress of the elastic body. Sensors operating in high-temperature environments should be heat-resistant, and additional insulation devices may be necessary.

2. Dusty Environments: Dust can infiltrate the sensor's interior, affecting component performance and causing short circuits. Therefore, sensors used in such environments should have sealed enclosures to prevent dust ingress.

3. Humid Environments: Humidity can lead to short circuits and rusting of the sensor, affecting both performance and lifespan. Sensors used in humid environments should be made of rust-resistant materials and have waterproof-sealed enclosures.

4. Acidic or Alkaline Environments: Exposure to acidic or alkaline environments may cause short circuits or damage to the elastic body. Sensors used in such environments should be made of corrosion-resistant materials with good sealing properties.

5. Electromagnetic Interference: The output signal of the sensor is susceptible to electromagnetic interference in the environment. In such cases, sensors with good anti-electromagnetic interference capabilities, preferably digital signal sensors, should be selected.

6. Explosive Environments: Explosive environments not only pose a risk of damaging the sensor but also present significant safety hazards for electrical equipment used therein. Therefore, sensors operating in explosive environments (such as coal mine shafts, entrances, and exits) must have explosion-proof performance that meets standards and undergo rigorous testing to obtain certification. Explosion-proof sensors used in such environments should have explosion-isolating sealed enclosures with adequate explosion-proof strength, and their circuits should comply with intrinsic safety standards.

7. Vibration and Impact: Large machinery in industrial environments can cause vibrations, and some operational devices may impact the belt scale. Therefore, sensors with a certain degree of shock and impact resistance should be selected, and care should be taken in choosing installation locations.

In summary, when selecting a weighing sensor for an electronic belt scale, it is crucial to consider the actual application environment and choose a product with high protection levels, compliance with standards, strong anti-interference capabilities, excellent performance, and precise manufacturing. Besides the working environment, the selection of the number and range of weighing sensors is equally important.

1. Number of Weighing Sensors: Generally, the number of sensors is determined by the structure of the electronic belt scale frame. The number of support points on the scale body determines the number of sensors used. Different forms of scale frame structures have already determined the corresponding number of weighing sensors.

For example, an ICS-17A belt scale is equipped with two weighing sensors, while an ICS-14A belt scale is equipped with four. Matrix-type belt scales composed of units each have four sensors per unit. The choice of scale body structure depends on various factors such as conveyor inclination, bandwidth, length, transportation volume, and application accuracy requirements.

2. Range of Weighing Sensors: This should be determined based on factors such as the maximum weighing capacity of the belt scale, the number of sensors configured, the weight of the scale body, and possible maximum offset fluctuations.

Finally, it is worth mentioning the quality and performance of Guonuo Technology's electronic belt scale weighing sensors, which feature digital signals, sealed enclosures, high protection levels, adaptability to acidic and alkaline environments, high accuracy, and strong stability. They also offer explosion-proof sensors. Importantly, when users are unable to choose, Guonuo's engineers will configure suitable weighing sensors based on comprehensive needs.
