FAQs about CANISTER LOAD CELLS 

There are many questions that people have when they are considering buying a canister load cell. Should I go with a shrouded or unsealed load cell?  Do I need to buy a canister load cell for my application?

This article will help you answer these questions and more. This is the perfect guide to answering any question you may have about purchasing a canister load cell.

What is a load cell?

A load cell is a device that measures the amount of force or pressure that is applied to it. There are many different types of load cells, but they all work in the same way. 

An industrial load cell, depending on the type, has a series of strain gauges that are attached to it.

These strain gauges will be able to measure any changes in the length of the load cell. The load cell will then convert this change into an electrical signal and send it either by cables or wirelessly to a computer for recording.

What is a canister load cell?

As the name suggests, this style of load cell is similar to the canister style, however instead of having a cylindrical shape they have a curved design. The curved design makes them very suitable for applications that have high load capacity and also require accurate readings or recordings. 

This canister load cell is the most common type of load cell and is used in many industries to measure the pressure and force applied to it.

How exactly does a canister load cell work? 

Load cells consist of a canister and an electronic circuit. The canister is the part of the load cell that holds the strain gauges and is usually made from steel.

The electronic circuit converts the mechanical movement into electrical signals, which are then transmitted to a computer system or display.

Canister load cells vs ring load cells vs pancake load cells ( what are the differences?)

The main difference is based on their structure and design. The canister load cell is generally composed of a steel canister, which has a spring loaded lid. The strain gauges are attached to the lid and when the load cell is placed on a flat surface, they will be compressed by the weight of the material being weighed.

Ring load cells are made from a metal ring, which is normally made of steel. The strain gauges are mounted to the outside of the ring and when a load cell is placed on the surface, the force applied will cause the ring to compress and this compresses the strain gauges.

Pancake load cells are usually made from a thin steel plate with strain gauges attached to the plate. The load cell is then placed on the plate, which compresses the strain gauges and results in an accurate measurement.

Canister load cells have many advantages over other types of load cells. They are relatively inexpensive and easy to use with their simple design, they can be very accurate at measuring forces up to 10 tonnes (11 tons), making them an ideal choice for many applications.

in common, these weight load cells are all available in portable miniature load cell options.

What protection degree requires for canister load cells? 

The protection degree for canister load cells is IP55. This means that the load cell must be capable of withstanding the following environmental conditions:

– Direct external pressure of 1.5 bar (22 psi)

– Temperature of -40 °C to +80 °C

– Humidity of 85% relative humidity (RH) or less

If the load cell does not have protection degree IP55, the operators must follow the following guidelines and take appropriate measures to ensure that the load cells are protected from damage.

What types of canister load cells are available?

Canister load cells are classified based on their physical features and construction. One way of classifying them is based on their size or diameter. Under this we have;

– Small Canister Load Cells (SCCs): These canisters are usually used in applications where the force is less than 10 tonnes. SCCs are usually used on small machines such as sieves, conveyors, and other similar applications.

– Medium Canister Load Cells (MCCs): These have a diameter of between 0.8mm and 1.0mm, which makes them suitable for use in applications with forces up to 10 tonnes, such as conveyors, pallets jacks, and other similar machines.

– Large Canister Load Cells (LCCs): LCCs are used where the force exceeds 10 tonnes, such as lifting equipment and cranes.

– Super large Canister Load Cells (SLCs): SLCs are used in applications where the force exceeds 20 tonnes, such as lifting equipment and cranes.

Other types of canister load cells include:

Carbon canister load cells: These canisters are used in applications where the force is less than 10 tonnes. 

These canisters are usually made of carbon fibre.

Steel canister load cells: These canisters are usually made of steel and have a cylindrical shape.

 Steel load cells come in different sizes, a feature that makes them suitable for use in applications. Keep in mind that most industrial load cells are made of steel.

Why is a canister load cell suitable for applications where high capacity and accuracy are critical?

One characteristic of canister load cells is high levels of accuracy and is also capable of handling high-capacity loads.

What makes canister load cells accurate?

A canister load cell has an internal spring which is used to maintain the load cell’s position within a small tolerance range. This spring is extremely accurate and can be adjusted over a much wider range than that of other types of load cells.

This is achieved by using a large number of wires in the spring, which are wound into a small space, whereas other types of load cells such as an electronic scale have springs that are too small.

What makes canister load cells suitable for high-capacity applications?

Canister load cell technology enables high-capacity applications to be built because it has a large internal volume and can withstand higher forces than other load cells. 

For example, the force required to lift 1 tonne with a steel canister load cell is only 0.5% of the weight of steel canisters.

How accurate is a compression load cell? (Measure range, readability…etc)

A canister load cell has an accuracy range of 0.01% to 0.5%. This is equivalent to the readability of 0.01% to 0.25%, which means that there is a tolerance of 1/10,000th of the reading for an accurate reading.

In terms of the weight range, the canister load cell has a tolerance of 0.25% to 5%.

How does canister load cell technology improve accuracy?

Canister load cells are more accurate than other types of load cells because of the spring mechanisms and the large internal volumes. Canister technology also allows for higher capacity loads, as it has a larger internal volume than other types of load cells and can withstand higher forces than other types of load cells.

How can I connect canister load cells correctly?

Canister load cells have a threaded connection that allows direct attachment to a load cell stand or to other canister-based load cells. The canister is loaded on the threaded end of the stand and then clamped in place for use.

When using a micrometer, it is important to make sure that the canister and micrometer are set at the same height, otherwise the reading will be inaccurate.

Why are canister load cells resistant to extraneous bending and side load forces?

Canister load cells are designed to withstand side forces and bending, which other load cells cannot. They are made of high-quality materials that make them more resistant to the effects of extraneous forces.

They are able to achieve this because of their design, which allows for a larger internal volume than other types of load cells.

The materials used is another reason why compression load cells are more resistant to extraneous forces. Urethane is used as the material for the housing that protects the electronic components and rubber bands are used for the load cell itself. This creates a hard, protective shell that does not allow any bending or sideloading to occur.

Construction is another key factor that contributes to the durability of canister load cells.

The housing is made of high-quality materials that have high tensile strength and are resistant to bending, thus being able to withstand side forces and other extraneous forces.

How do I clean canister load cells?

Canister load cells are easy to clean, as they have no moving parts. To clean a canister load cell, simply remove it from the stand and wipe it with a paper towel. 

If there is dirt or debris on the surface of the canister, you may need to use a soft brush or cloth to clean it.

 Do not use solvents or chemical cleaners on your canister load cell; these will damage the surface and cause corrosion.

What is the average life span of a canister load cell?

The life expectancy of a canister load cell depends on the manner in which it is used, as well as its environment.

 If the canister is put in an area that is moist and humid, it may corrode faster, because moisture is a corrosive agent. Regular cleaning will reduce this corrosion effect.

Canister load cells are designed to be used indoors and in areas that have low humidity levels. The average life span of a canister load cell ranges from three to five years, depending on the environment where it is being used.

Where to buy canister load cells?

Canister load cells or compression load cells can be purchased at most parts stores, such as NAPA Auto Parts or Amazon.com. You can also purchase canister load cells online at a variety of websites,  where you can find them for a good price.

You can also buy canister load cells from reliable suppliers and manufacturers in China. This way, you can purchase canister load cells at a good price and get them shipped to your home or business.

It is important to purchase a quality canister load cell; otherwise, you will not get the accurate readings that it is designed to give you.

How do I choose canister load, cell suppliers?

There are many reputable suppliers of canister load cells. Choosing one is not an easy task. You have to consider the following:

Do they have a good reputation?

This is an important factor to consider when purchasing a canister load cell. If the supplier does not have a good reputation, you will not be confident that you are purchasing a quality product that has been tested and inspected prior to leaving their warehouse.
