The HBM load cell refers to the strain gauge created by the HBM Company. This is the most popular load cell in the world due to its high performance and accuracy.
Load cells are critical in various industries, including construction, automotive, and aerospace. In these industries, there is need to measure heavy objects or structures without endangering lives. These load cells come in various shapes with unique features that suit the diverse requirements of the user's operations.
The load cells include:
S-beam load cells
The S-beam load cell resembles the letter S; hence, this name. This type of load cell measures both tension and compression. Therefore, it is versatile and is commonly used in hanging scales, material testing, and tensile testing machines.
Shear beam load cells
Shear load cells become stressed when a load is applied, causing the load cell to bend at specific points. The main advantage of this design is it better accommodates off-center loads than other styles. For this reason, shear beam load cells find usage in industrial scales, particularly in hopper and tank weight measurement systems.
Compression load cells
Compression load cells are similar to the shear beam cells. However, they are designed to measure compressive forces rather than shear forces. They, therefore, excel in static weighing applications, particularly in industrial scales and heavy machinery. They are often used in pile scales, which are used in civil engineering projects with heavy piling.
Ring load cells
A load cell ring takes an unusual shape as a ring or donut. This load cell measures tension and compression simultaneously. This feature makes it ideal for applications like aviating components weighing during your forklift and other heavy-duty vehicles.
Load cells are often required to survive in difficult industrial environments. These include high humidity, extreme temperatures, and possible mechanical shocks or vibrations. That's why their durability becomes a critical consideration.
Moreover, the construction materials directly impact the longevity and performance of the load cells. So understanding steel's versatility and moisture's detrimental role can help business owners select appropriate load cells for their environment.
Ingress protection
Most load cells are equipped with Ingress Protection ratings. These ratings offer protection levels against dust and water. For example, an IP67-rated load cell can survive dust exposure and water submersion of up to one meter for at least 30 minutes.
Housing and mounting
Camera housing is integrated into some load cells over the outer casing. The casing serves as protection against impacts and other environmental hazards. In harsh outdoor environments, load cells are secured with additional mounting brackets or guards. These features prevent dislodgment and protect them from other hazards, such as debris.
Shock and vibration resistance
Many industrial applications expose load cells to high levels of shock and constant vibrations. These include construction and mining. To survive such conditions, the load cells feature designs like dampening elements and rugged internal supports. These features help absorb shocks and dampen vibration transfer to maintain measurement accuracy.
Materials
The inner circuitry of the load cells is made of strain gauges. These strain gauges are often attached to robust materials like stainless steel or aluminum alloy. These materials are highly resistant to deformation, wear, and corrosion. In industrial applications, steel is often the material of choice for load cells.
This is because steel offers unparalleled strength and resistance to fatigue. On the other hand, aluminum load cells are commonly used in conditions where users require lightweight components. Unfortunately, although aluminum does offer some resistance to corrosion, it is not as robust as stainless steel.
Load cells have an enormous scope of usage across many spaces. People can find the place where load cells excel. These include weighing, force measurement, and ensuring quality control in manufacturing. The features that make load cells versatile to cater to these applications are their accuracy, adaptability, and capacity to measure both static and dynamic loads.
Industrial and commercial truck scales
In transportation, load cells are used to weigh trucks and other trailers in motion. The companies install the load cells into the weighbridges and the portable scales. They help the companies evaluate the weight of the vehicles before they enter the confined roads.
Materials and structures testing
In construction, load cells test the materials and structures' weight-bearing capacity. Companies use the load cells to evaluate concrete beams. Then, they assess the maximum load the design can tolerate.
Pressure Measurement
In the medical field, load cells help gauge patients' blood pressure. They measure the force exerted by blood against the vessel walls. The precise readings ensure the doctors have accurate data for better diagnosis.
Energy generation system
In the power generation fields, load cells monitor and optimize the work of turbine rotors. The cells then measure the tension in the rotor's fibers during production. It lets the technicians catch distortions early.
Quality control system
During production, load cells check if the packages contain correct amounts of products. They measure each package's weight in real time to guarantee consistency in distribution.
Since load cells come in various types, business owners should consider some factors to select the ideal cells to measure weight for their products. Here are the factors to consider:
Maximum load
Deciding on the maximum load a load cell can measure is crucial to avoiding catastrophic failures. Larger loads require complex designs. Therefore, load cells should be chosen based on the heaviest load to measure and workload conditions.
Sensitivity and precision
The required precision level determines the load cell's sensitivity and strain gauge's performance. Highly sensitive load cells, like the ones with HBM strain gauges, are ideal where small weight changes are crucial, for example, in laboratories and pharmaceutical plants.
Installation
How easy it is to install and integrate a load cell will affect the overall efficiency of a corporation. Some load cells can be complex, require additional machinery, and take a long time to fix. On the other hand, others have simple mechanisms and are easy to fit. Consider the accessibility and adjustability of the load cells.
Environmental factors
If the company's operating area exposes the load cells to extreme temperatures, humidity, or dust, select the suitable load cells with corresponding ingress ratings. Also, the company's vibration levels are a crucial consideration, as continuous vibrations can affect the measurement accuracy of the load cells.
Response time
Promptly detecting changes in the load is crucial in some applications such as mining or cargo weighing. In such cases, companies should consider using load cells with fast response times. These cells should also have minimal hysteresis to avoid delays in the system.
Yes, a wide selection of high-quality products, including reliable load cells, awaits everyone in China. They are manufactured by skilled workers using cutting-edge techniques and materials. They ensure the cells have the accuracy and strength to undertake demanding tasks. Moreover, the nation offers them at competitive prices, giving them an edge over other countries
Business owners can purchase these load cells in bulk, as they make one bulk order from trustworthy suppliers. Wholesale is the most affordable way of getting numerous products to fill up a retail shop. Moreover, bulk purchase minimizes the costs associated with getting individual items.
The load cells in diverse types include the S-beam load cells, which measure tension and cumulus load cells that measure compressive force. These load cells types are then chosen based on the application environments.
The load cells have inexpensive grading materials. These include corrosion-resistant materials such as stainless steel. They also come with protective casings that shield the cells from environmental debris, water, and extreme temperatures. Additionally, the shock-dampening internally design elements enhance the load cells' longevity for many years.
