Measuring high volume weights with extreme precision is almost imperative for industries like mining, farming, and resource extraction. However, measuring them in a timely manner is also important and that is exactly what was introduced in 2005.
On-board truck scales allow weights to be measured as they are loaded to the truck, unlike the traditional scales that require the driver to drive over them. Simply put, on-board scales are mobile traditional scales if not better.
Types of On-board Truck Scales
There are mainly two forms of on-board truck scales: Load Cell and Air Suspension. Air suspension technology is more characteristic to the traditional scales hence load cell has become the dominant form of such scales.
The Load Cell technology is of transducer nature which means scales of this type transform forces like pressure into electrical signals. These signals are then interpreted in a handheld reader or a similar device. Since the reading is presented in digital form, the reader can make more precise decisions.
Technology Behind On-board Scales: Sensors and Indicator
Sensors: An on-board truck scale has either the air suspension sensors or the mechanical sensors. Although the latter is more modern some companies also produce hybrid scales that use both types of sensor. Sensors are installed on a truck’s axle groups so their numbers depend on how many groups there are in a truck. They measure “per axle weight” in addition to changes in weight, temperature and deflection and then turn them into electrical signals. Modern on-board scales can measure these data up to .1% of GVW or gross vehicle weight.
Indicator: The indicator works as the receiver and interpreter of the electrical signals mentioned earlier. On-board scales come with mobile handheld indicators that can give accurate reading within a 500 ft radius. The range varies from brand to brand though.

Advantages of On-board Truck Scales
Obviously these scales are more efficient than traditional scales but it is better to see precisely why they are defining the future of payload management. Let us take a look at the conveniences an on-board scale offers.
- Risk of overloading is almost entirely eliminated since the weight is collected and shown as the truck is loaded.
- Since overloading can be taken out as a possibility, related damages can also be drastically reduced.
- Next, this is more time efficient choice. In a traditional scale a truck has to drive over a fixed scale and drive back if it is either overloaded or under-loaded. A great deal of time can be saved with this simple functionality.
- On-board scales also increase a truck’s fuel efficiency by reducing repetitive motions for weighing loads over and over to get them right.
- 13% of truck accidents occur due to overloading according to studies. Some even occur while driving to the truck scales. On-board scales drastically reduce this possibility.
- Finally, by combining all the advantages mentioned, a truck’s total durability can be increased to quite some degree.
Other than the direct benefits mentioned earlier, on-board truck scales for sale also help in avoiding legal problems arising from overloading, increasing return on assets and operating efficiency. For these reasons, on-board scales will most possibly take over the traditional or railroad scales in the near future.
