Weighing is a fundamental process used in various industries and applications to determine the weight of objects. 

When it comes to weighing, two commonly used methods are:

1. Static weighing

2. Dynamic weighing. 

Vehicle weighing is important in order to comply with road regulations in many countries

Although they both serve the same purpose, they differ in terms of the process and the scenarios in which they are employed. 

In this blog, we will explain the difference between static and dynamic weighing, shedding light on their respective features, benefits, and applications.

Static Weighing

Static weighing refers to the process of measuring the weight of an object while it is at rest, without any movement. 

It is a traditional weighing method that has been used for centuries.

Static weighing is typically performed on platforms or scales that are designed to handle the weight of the objects being measured. 

These scales are calibrated to provide accurate and precise weight readings.

Features of Static Weighing

       1. Stability: In static weighing, the object being weighed is stationary, which ensures a stable environment for measurement. This stability helps to obtain accurate weight readings.

        2. Precision: Static weighing is known for its high precision. Since there is no movement involved, it allows for more precise measurements, particularly when dealing with smaller increments.

        3. Durability: Static weighing scales or platforms are designed to handle heavy loads and withstand the rigors of industrial applications. They are built with sturdy materials, ensuring long-lasting durability.

Applications of Static Weighing

Static weighing finds applications in various industries, including:

        1. Industrial Manufacturing: Static weighing is extensively used in manufacturing processes to measure raw materials, components, and finished products. It helps ensure quality control, inventory management, and compliance with regulations.

        2. Logistics and Warehousing: In logistics and warehousing operations, static weighing is employed to determine the weight of packages, pallets, and shipments. It aids in calculating shipping costs, optimizing load distribution, and ensuring safe transportation.

           3. Agriculture: Static weighing is used in the agricultural sector to weigh produce, livestock, and feed. This information assists farmers in monitoring crop yields, managing livestock, and controlling inventory.

Dynamic Weighing

Dynamic weighing involves measuring the weight of an object while it is in motion.

Unlike static weighing, dynamic weighing takes into account the dynamic forces acting on the object during the measurement process.

This method is commonly used when weighing objects that are constantly moving, such as vehicles, conveyor belts, or flow systems.

Features of Dynamic Weighing

        1. Speed and Efficiency: Dynamic weighing allows for faster weighing processes compared to static weighing. It eliminates the need for objects to come to a complete stop, enabling continuous weighing in high-throughput environments.

        2. Real-time Monitoring: Dynamic weighing systems can provide real-time weight data as the objects move. This feature is especially useful in quality control and process optimization, allowing for immediate adjustments based on weight fluctuations.

        3. Impact Resistance: Dynamic weighing systems are designed to withstand the impact and vibrations associated with moving objects. They are equipped with specialized load cells and sensors to accurately measure weights even in dynamic conditions.

Applications of Dynamic Weighing

Dynamic weighing is applied in various fields, including:

        1. Transportation: Dynamic weighing plays a crucial role in the transportation industry, especially in weigh-in-motion (WIM) systems. These systems measure the weight of moving vehicles on highways, enabling enforcement of weight regulations, preventing overloading, and ensuring road safety.

        2. Material Handling: Dynamic weighing is employed in conveyor belt systems to measure the weight of bulk materials, such as grains, coal, and minerals. It enables accurate inventory management, process control, and efficient material flow.

        3. Packaging and Filling: Dynamic weighing is utilized in packaging and filling lines to ensure the correct amount of product is dispensed.

At Camaweigh, one of our most popular products, the CW Portable Axle Weigher can serve both for static and dynamic weighing.

What Equipment Can I Use to Measure Both Static and Dynamic Weighing?

The wireless portable weighing pads of the CW portable axle weigher allow you to undertake both static and dynamic weighing. Although all the pads are the same, the only difference is on how you plan to measure.

Weighing pads  that can be moved and portable are crucial for dynamic weighing.

For example, under dynamic weighing, the vehicle needs to move at a speed of less than 5 km/hr without stopping. For this you would only require two pads and one indicator.

If you plan to undertake static weighing, the pads will operate like a weighbridge and therefore you will require 2 pads for each vehicle axle.

For example,if you have a truck with 3 axles, you will need 6 pads ,4 axles will need 8 pads and 

so on. During measuring, the truck needs to be stationary and each wheel should be on top of a pad.

Conclusion: Dynamic Weighing versus Static Weighing

In conclusion, the key points differentiating static and dynamic weighing are as follows:

Static Weighing:

• Measures the weight of stationary objects

• Offers stability, precision, and durability

• Suitable for industries like manufacturing, logistics, and agriculture

Static weighing using weighbridges is an example of traditional static weighing

Dynamic Weighing:

• Measures the weight of moving objects

• Provides speed, efficiency, and real-time monitoring capabilities

• Applied in transportation, material handling, and packaging industries

Dynamic weighing allows real time weighing and move flexibility for weighing

Both static and dynamic weighing methods are essential for accurate weight measurements, quality control, and compliance with regulations in various sectors. Choosing the appropriate method depends on industry requirements, object characteristics, and desired precision and efficiency.
