Load Cells For Weighbridge: A scale is a set of scales used to measure heavy objects. Load cells are installed on a concrete surface and contain electronic and digital displays to show the weight of the measured object. Weighbridges are mainly used to measure the weight of trucks, trucks, containers, and other vehicles used to transport goods. Weighbridge load cells are more reliable and accurate, helping industries, mining and quarrying, electrical equipment, iron and steel, household appliances, metallurgy, liquid industries, and construction to measure incoming and outgoing goods.
Types Of Weighbridge
Load Cells For Weighbridge: The weighbridge is differentiated by use and design of the load cells and the place where it is used.
1. Electronic Pit Type
Electronic pit type is the most commonly used design for public domain weighbridges where the surface is flat and vehicles can approach from any direction and it requires less space and is less expensive.
2. Electronic Pitless Type
Electronic pit-less types require more space and are a bit more expensive. These types are constructed in ram bases where vehicles can approach from only two directions.
3. Rail Weighbridge
Rail weight bridges are used to measure weight of trains and wagons which helps in building trains more balanced for better safety.
4. RCC Weighbridge
Rcc weigh bridges are extremely strong and cost effective which are made of concrete and steel. Concrete will be intact for a lifetime but the steel’s lifespan is around 10-15 years.
Load Cells For Weighbridge Designing
The important factor of a weighbridge is its design and choosing of load cells. The load cells used in weighbridge are extremely accurate and precise.it is very important to choose the right load cell. If an unmatched load cell is paired with a weighbridge it leads to poor performance and failure of the weighbridge.
Uses Of Load Cells For Weighbridge
A weighbridge is commonly used most of the heavy manufacturing industries like mining, quarries, electrical equipment, iron and steel, household goods, metal, liquid industry, construction, trains and weighbridges are used by government officials for measuring overload vehicles and it is widely used in transport business where transactions are made according to the amount of goods sent.
Load Cells Used In Weighbridge
Load Cells For Weighbridge: Types of load cells used in weighbridge hydraulic load cells, shear beam load cells and pancake load cells each differ in its function, construction, cost and building a weighbridge.
1. Hydraulic Load Cells
Hydraulic weighbridges perform extremely well in most environments, and using this type of load cells we don’t come across a lot of issues. It performs well even if the surface is moist. Hydraulic load cells utilize hydraulic fluid to transmit force applied to the scale weighbridge to pressure transducers. System based on this type of load cells is more expensive than analog cells. This type of load cells operates only on hydraulic pressure, that means electrical equipments are not used in the hydraulic weighbridge. Hydraulic load cells uses hydraulic fluid to transmit force applied to the weighbridge to pressure transducers, converting force into an electrical signal.
Advantages
- Load capacity upto 50 tons
- No water damage
- Steel and concrete layouts
- Works well in high temperature
- Low maintenance and easy installation
2. Shear Beam Load Cells
Shear beam load cells core component is a spring element.as loading this load cell it forms a strain which a strain gauge picks up and converts into an electrical signal where we measure the weight of the load. Shear beam load cells can be calibrated for different types of units like grams, kilograms and tons. Shear beam load cells are protected with good rating which is dust proof and splash proof. This load cells is of two types single and double ended load cells. Single ended load cells are used for medium loads like upto 5 tons as well double ended load cells are used to measure heavy loads upto 30 tons and the double ended shear beam load cells have two spring elements and are calibrated for grams, kilograms or tons and are most suitable for silo scales, container scales, vehicle scales and weighing frame.it is easy to calibrate as well
Advantages
- Less space very cost efficient
- Have ip ratings so the durability is good
- Used in most of the weigh bridges so product availability and service is easy.
Pancake Load Cells
Pancake load cell is also known as low profile load cell, because it has a low profile design and it looks like a pancake. On the other hand, pancake load cells can bear both tension and compression force. So it is also a tension and compression load cell that is widely used for platform scale, truck scale, rail weighbridge. The elastic element of pancake load cell is a hole-structured elastic element. Its whole structure looks like a wheel, and multiple mutually distributed tension have been formed between hubs and tires. The pancake load cell is flat and large. Measuring capacity of pancake load cells is 5 tons and more as well choosing the right load cell is the key feature.the pancake load cell has a shorter height and a larger diameter which is very easy to install.
Advantages
- high overload capacity
- Strong unbalanced loading resistance performance
- Good for high tension and force
FAQs: Load Cells For Weighbridge
Q. How accurate is the pancake load cell?
A pancake load cell is highly accurate with 0.03-0.10% of error. It is accurate for both tension and compression force measurements, and provides both digital or analog output.
Q. Does a pancake load cell come with a display?
A pancake load cell provides digital or analog output on the display screen.
Q. Which material is used for a pancake load cell?
A pancake load cell is a low-profile load cell made from welded stainless steel or aluminum. This material is sturdy as well as little elastic to the load cell that plays a major role in complete operation.
