What is car weigher

The car dynamically passes or stands still on a weighing table with a certain width, and the weighing table weighs the weight of each wheel, and then the axle weight and the total weight of the car are accumulated! This weighing process is a strong real-time process, requiring sensors to quickly collect the wheel axle weight of the car and calculate the total weight.

The working principle of the weighing platform is as follows: when a weight is applied to the weighing platform, the sensor of the weighing platform releases a voltage signal, and the output signal is proportional to the weight of the weight. The signal is transmitted to the amplifier and amplified, Then it is converted into a digital signal by the analog-to-digital converter and displayed on the display.

A single board is the wheel weight value of the car, and the two boards are the axle weights. According to the axle type of the car, the total weight of the car can be added up.


In addition, the sensor of the weighing platform now uses an embedded structure sensor. Compared with the previous integrated sensor, the embedded structure sensor has the advantages of higher pressure resistance and higher accuracy. Saintbond axle scale uses this kind of sensor, with wireless transmission. The working principle of the load cell is: when the weighing platform is deformed under pressure, it will change the resistance value of the resistance strain gauge in the sensor, thereby changing the signal output. The meter collects the signal and performs signal calculation and display.

The above picture shows the weighing platform, the instrument and the latest handheld instrument that supports license plate recognition.

This is the weighing platform, the shell is made of aerospace-grade cast aluminum alloy material, and the two sides are folded wheel approach bridges made of engineering alloy. Wireless transmission meter supports handwriting touch input. Built-in micro high-speed printer. The function of the meter is mainly to receive sensor signals, calculate and analyze the signals, and convert them into intuitive numerical display!

So what is an axle scale?

First thing’s first, let’s start with what exactly an axle weighing scale is. An axle weighing scale measures the weight of each axle of a truck, a commonly accepted way to determine the truck’s overall weight.

This method is considered to be the most accurate weighing system, measuring within a margin of error of 0.2%. Scale owners and operators love them because they are low profile, easy to transport and compatible with forklifts.

Vehicle axle weighing scales come in many different sizes and maximum capacities depending on their design and use.

There are two main types of axle scales; portable and fixed. Portable axle scales are much more cost-effective in addition to the added benefit of moving the scale anywhere at any time. While axle weighing scales are most popular in the trucking industry, they are also used in the mining and farming industries.

Axle scales are typically built with aluminum only to help with durability as well as being lightweight.

Why should we use an axle weighing scale?

With all of the different types of truck weigh scales available, you might wonder why some companies choose to use an axle scale over other types.

They Can Be Dynamic

Because axle scales can measure while the vehicle is still in motion, it is easy to quickly check whether the load is overweight or not.

Stable or Dynamic? The Choice is Yours

Truck Axle scales come in either dynamic or stable models so depending on your industry you can choose what suits your business best.


Axle scales are remarkably accurate and all have fairly high capacities so they are suitable for a wide variety of industries.


Compared to other scales, Truck axle scales are considered to be cost-effective because they don’t need to be given a constant power supply. Once it’s charged, it can operate for a good length of time.

How does an axle scale work?

Now that we know what an axle scale is, its time to talk about how an axle scale works:

1.The vehicle is made to run over the scale so the wheel load is over the proper loadcells. Unlike other scales where all four wheels must be still in order to obtain a measurement, axle scales can work while the vehicle is still moving, even up to almost 5 km/h.

2.As the vehicle passes through the scale, the metal plates underneath bend and gauge the pressure emitted from the tires above. The more stress on the plates, the more weight the scale calculates.

3.The scale records the weight derived from each of the individual wheels and adds all of the weights together, known as gross weight.

Axle scales have revolutionalized the way we measure heavy vehicles and loads by making it easier and more efficient to weigh different loads. Some
