Onboard weighing systems are also referred to as portable wheel weighers. They are some of the most convenient and versatile weighing equipment. These scales are installed onto the vehicle and remain permanently attached there as opposed to fixed location weighing systems like weighbridges. They can accurately measure the weight of the load as it is being loaded onto the vehicle.

These scales are mainly used in the transportation, mining, farming, and logistics industries. Onboard weighing system scales can either be fixed onto tractors, trailers, normal trucks or haul trucks. They measure the weight of the load in real time as it is loaded onto the truck. The data is then recorded and stored for later analysis.

Components of On-Board Weighing Systems

Onboard weighing systems come in a variety of forms to suit different user needs and weighing requirements. The onboard weighing systems feature the following components:

  1. Load Cells

These use a weight air transducer that converts into a quantifiable electric yield over a power. They’re used in suspension and freight trucks. The heap cells are used to identify descending power via pressure, tension, and bowing.

  1. PSI Gauges

These gauges are mechanical and they’re used in agriculture­related sectors. The weight is displayed via standard PSIs, accurately.

  1. Wireless Operations & Software Sync

This is a digital weight monitoring device that is operated remotely. When the maximum load capacity is reached, the system sends out an alert.

  1. Analog Weighing

These onboard weighing systems are calibrated in Kilograms and work on air suspension for trucks.

Why Onboard Weighing Systems

Onboard weighing systems eliminate the need for guesswork when dealing with vehicle weights. Guesswork would otherwise result in overloading, stock loss, and accidents. Onboard weighing systems have a lot of benefits compared to the conventional scale systems. The benefits include:

Accurate Measurements

Onboard weighing systems feature precise technology that measures the load accurately. These systems measure the exact quantity of the load and can take up minor fluctuations in the gross weight of the vehicle.

Time Efficient

The load needs to be weighed only once. This will reduce the time wasted going back and forth to other locations to access fixed weighing systems.

Cost Effective

Onboard weighing systems do not need too much manpower, unlike the traditional scales that required many people to coordinate the entire process leading to increased costs.


Onboard weighing systems can be used on different types of vehicles, in different terrains, and under different conditions.

No more unnecessary loss of stock

Overloaded trucks can cost you a lot of money as well as your customers. Getting an onboard weighing system will ensure that the trucks will only be loaded with the correct load and arrive at their destination with the same load. This way you will always be sure that your customers get exactly what they pay for.


Onboard weighing systems do away with guesswork and human error by letting you know exactly how much your load weighs. Always ensure that your trucks are loaded correctly as this will increase productivity and save you a lot of time and money.

When choosing the type of onboard scale to buy, one should take into account the type of vehicle to be weighed, the amount of weight expected, and whether the gross weight is required.

Lastly, it is recommended that one only gets reputable brands that are accurate, versatile, and require minimal maintenance.
