Каков принцип работы тензодатчика колонного типа?

Всем привет!

So today we are going to discuss a very interesting topic regarding weighing accurately. Have you ever wondered how we weigh things that are quite heavy such as cars or airplanes? As scary as it sounds, we perform this task using a simple tool known as a load cell. A load cell is a device that converts an object's weight into an electrical signal that we can read. This allows us to know precisely how heavy something is. The column type load cell is commonly used in most places. Let’s go deeper into the logic behind column type load cells to understand how they work!

COLUMN TYPE LOAD CELLS

A column type load cell consists of many columns stacked vertically. These are columns can be structured like circles or rectangles. They are made from a smart material that can take another form when weight is applied to it. So, if you place something heavy on the load cell, the columns will bend slightly or change shape. This change in shape induces a change in the electrical resistance of the material. Imagine electrical resistance as the ease or difficulty of electricity moving through the material. This change can be measured using electronic devices, which gives us an idea of how much weight is placed on the load cell.

Как работает Column Type Load Cell Работа?

The shape change occurs due to a scientific principle known as the piezoelectric effect. That is a fancy term for some materials creating electric charges when they are patted or stretched. In a column type load cell, weight is applied at the top of the columns through a platform or via a rod that connects the top and bottom of the columns. When weight is applied, columns change shape slightly and an electrical signal is created. This signal is intrinsically linked to the weight we are measuring and gives us the information on how heavy it is.

Column Type Load Cells Working Steps

Тензодатчик колонного типа working principle can be summarized in 4 simple steps:

Compression: When pressure is applied to the platform or rod, the downward force applies pressure to the columns. That means that as you press the columns down, they become a little shorter.

Strain: The compression creates strain in the columns. We use the term strain to describe the stress on an object. This strain impairs the columns' electrical conductivity.

Deformation: The pillars change shape a little bit as the strain of being loaded from the weight applied on them. This slight change creates an electrical signal that corresponds to the weight of the load. The more mass, the greater the deformation and the stronger the electric signal.

This electrical signal is subsequently transmitted to electronics that process the information. “The electronics amplify the signal, filter it out and converts it into something that is a weight measurement that we can easily read on a display.”

Examples of how column type load cells operate

Чтобы полностью понять, как column type load cells function, it is important first to consider their components and the anatomy of each component. The platform or rod point where the load capability is used. This is important because it is the columns that generate the corresponding electrical signal that is based on the weight. Lastly, the electronics interprets this signal to display weight accurately. It is this cooperation between the components that ensures the load cell performs its job.

What is the Purpose of Column Type Load Cells?

Column type load cells are mainly used as highly accurate weight measuring devices. This precision matters a lot across roles and sectors. Accurate weight measurements are essential for safety, quality control and operational efficiency. For instance, in the automobile industry, the weights of car parts could assist with their safety. For construction,load cell sensor knowing how much something weighs is necessary to ensure that buildings and structures are strong and safe. Column type load cells are used in various industries including automotive, aerospace, construction and manufacturing.

Some connecting wires for these applications are trainable devices that help you quickly determine the techniques of these devices. These devices function by turning the change in form of the specialized material into an electrical signal, which is processed and displayed as a weight measurement for us to read. SOP is a few trusted brand that provides reliable and accurate column type load cells for many industries. Knowing how these load cells work allows us to appreciate the science behind accurate measurement of weight and the importance of reliable tools in all fields. These devices make our lives much easier by allowing us to know the weights of heavy objects with great safety and efficien
