Pfreudt Weighing Technology for Onboard Scale Systems

One of the most important process in the mining industry is accurately weighing each load. Typically every load is carried to a weighing unit, and are put on a stationary scale to get the accurate measurement. This is not only common in the mining industry, but several manufacturing industries use the same method to measure each load before they are carried off towards their destination.

Carrying the load to a isolated stationary scale has been the norm for years. However, this additional trip to the weighing unit increases the overall cost of transportation. This may not seem much but in an industry where large shipments needs to be weighed everyday this can add up to be quite a cost.

The people at Pfreudt has an ingenious solution. Their onboard weighing systems can be fitted to a loading vehicle such as a fork lift, wheel loader or an excavator. Once fitted, the system measures the weight of each load while they are being loaded. This completely eliminates the need to carry a load to a distant weighing station saving both time and money.

Although Pfreudt is an international company, only select companies in the U.S. specialize in Pfreudt onboard systems. One of the most trusted sources is Walz Scale, a leading global supplier of Pfreudt-based onboard scale systems.

Realtime Measurement: The fact that onboard weighing systems are capable of weighing loads during the loading process eliminates the need of correction post loading. This is because the operators are armed with realtime data and can make adjustments during loading avoiding overloading.

Saves Time: As mentioned before with loading vehicles capable of measuring loads there is no need to carry them to a stationary weighing unit. This real time weighing eliminates the need to correct under or overloading. This significantly reduces the overall loading and transportation time. This means the consignments reach their destination faster.

Saves Money: This technology saves money in two ways. Firstly by it saves fuel cost which would otherwise be spent to carry the load to the stationary weighing units. More often than not, weighing stations are owned by independent businesses, so it also saves the service charges of weighing the loads.

Increased Connectivity: These ingenious weighing scales from Pfreudt automatically stores weighing data which can be later transferred to PC for analysis. This data can easily be used to keep an eye on the loading details and can be used to calculate annual savings. The scales are USB and wireless compatible making them perfect for most computer systems. Users are also given access to Pfreudt webportal which allows them to access the data from any location in the planet.

How Do On Board Truck Scales Work?

On board truck scales were introduced several years ago to help operators weigh and monitor the loads of heavy duty trucks and equipment. With the scale system tangibly equipped on the actual trucks and equipment themselves, on board scales have helped to enhance the efficiency of weighing payloads (such as mining resources, crop harvests, etc.) making any weighing operation more streamlined and profitable.

The technology behind on board truck scales has evolved drastically over the years, making them more simplistic and affordable. In this article, we discuss the functionality and features about today's on board truck scale systems.

Features of On Board Truck Scales

Unlike platform-based truck scales, on board truck scales have load cells, which are designed to withstand vehicles that are filled to capacity. They have a digital indicator that displays the vehicle’s weight throughout. There are audible and visual set-point warnings that allow truckers to capitalize on payloads.

The main component of the weighing system has numerous load cell sensors that bolt a truck chassis and its body. The sensors are used to accommodate the entire weight of the truck body. They are very accurate and can be customized to make sure they can withstand additional weight when a vehicle is overloaded. The sensors come in a variety of sizes to suit the wide range of vehicle bodies.

Operation Behind On Board Truck Scales

On board truck scales operate in a simple way. The scale is wired through the truck's ignition switch to keep it active each time the vehicle is in use. Truckers do not have to press any buttons to operate the scale. The truck’s weight will simply appear on a screen inside the vehicle.

On board truck scales have easy to use digital displays on the indicator. The weight is displayed every time the truck engine is on. The scales have three set points that act as warnings to the truckers. A plug-in keypad is used to set the set points to make sure they are not interfered with when the truck is being operated. The keypad is unplugged once the points are set and the scale is ready for use. A red light appears on the display when two of the three set points are exceeded. When the third set point is surpassed, a buzzer sound is produced. Some of the weight on the truck has to be removed for the buzzer sound to go off. The combination of audio and visual warnings ensures the truck is within an acceptable weight.

Applications Beyond Trucks & Vehicles

On board scales can be used in other applications besides trucks. They are also applied in conveyer belt systems. The belt scales are used to measure the flow rate or weight of material that travels over a conveyer belt. These scales are integrated into the belts and use a microprocessor system to perform the calculations. Some of the conveyer belts are customized to stop the belt from moving when a specified mass if attained. They can also have alarms that indicate a problem with the conveyer system. These on board scales are widely used in mineral extraction, ship loading and port handling.

The rail industry relies on the on board scales to prevent overloading. Some of the loads transported by rail have to be weighed. Rail scales are essential to ensure that the trains are not overloaded. Overloading can compromise safety and this makes on board scales vital. The scaled are installed inside the train and if it is overloaded, it sends out a warning.

Many manufacturers now make on board scales for a variety of applications; however, only few are capable of producing highly accurate and fully-support on board scale systems. Companies like Walz Scale (with a dedicated branch coined Walz Onboard ) showcases some of the best technology on the market. Walz Scale's on board scale systems are custom tailored to all types of vehicles and heavy duty machinery, such as conveyor belts and grain dump trucks (for farmers.) Pioneers like Walz Scale are the go-to companies to work with when it comes to dependable and accurate on board scale systems.

Revolutionized Technology of Onboard Scale Systems

Electronic onboard scales were unveiled about 3 decades ago to address the need for efficient measurement of truck load weights when platform scales were not available. In the passage of time and with constantly evolving technology, onboard scale systems were revolutionized by some of the brightest minds in the heavy-duty weigh scale industry.

The load cells on electronic onboard scales were revamped while specialty load cells were invented for center hangers, single points, fifth wheels and various other types of suspensions. But that's just the tip of the iceberg on how onboard scales have progressed over the years. Below we go into greater detail about the technological developments and overall evolution of onboard scales.

Evolution of Onboard Scales

One of the most recent developments on today's onboard scales is the double shear beam load cell. This advancement transformed into an industry standard in timber and other similar industries. Strain gauge based air sensors were developed and augmented for an elevating number of air ride suspensions.

Vehicles with hydraulic lift cylinders are not left in the dark for we also now have hydraulic sensors. In fact, the market offers onboard scales for spring, air and mixed suspensions. It now becomes a matter of preference and not merely the availability of choice.

Advantages of Advanced Onboard Scale Systems

Aside from the convenience, onboard scales can significant increase productivity and operational efficiency. Having an onboard scale means that you do not have to always drive to the loading area to rework your load. Given that, you may increase the numbers of load delivered or hauled in a day.

Most onboard scales, like those produced by Walz Onboard, can guarantee the accuracy of the measurements made the first time, saving time as energy is ensuring that you are complying with the weight requirements and also to commensurately price the services you render. Overweight fines will decrease significantly if not completely eradicated from your monthly dues so as to maximize the profit.

Other Benefits of Having an Onboard Scale

There are many industries that are powered by onboard scales today. As mentioned before, the trucking industry is one that reaps its benefits. But the mining industry is also becoming more efficient in terms of measuring precious materials like gold and other gems because of onboard scales. They will immediately know the amount they have gathered, quickly calculating if they have met their required output.

In Motion Rail Scales 

Onboard scales can also be integrated in rail cars, thereby creating rail scales that can measure load weight while the contents being weighed are in transport on trains. In motion rail scale systems are perhaps the most advanced form of onboard scale technology. Companies need not to worry about usual challenges in the maintenance and operation of their rails like cutting, drilling or welding when they set it up. In a matter of a day or two, in motion rail scales can be installed, providing more efficiency than ever. Having these onboard scales in comparison to other alternatives can pay significant dividends.

Revolutionizing Operational Efficiency

Utilizing the utmost capacity of your company entails having efficient systems. Onboard scales are an important tool in making every haul contain the maximum legal load, wasting no effort and time in delivery. No more worrying about the trip to certified loading stations, saving the money you would use for gas. The maintenance cost will be kept to minimum because with the knowledge of the weight you carry, you no longer burden the vehicle with mass that it is not designed to carry. Not only that, you also increase your credibility to your customers since you provide them with accurate weight information, encouraging repeated subscription to your services.
