On-board Scales Optimize Weighing Processes for Logistics Warehouses
External, platform-based scales (i.e. pallet scales, conveyor belt scales, truck scales, etc.) have been the conventional standard for most logistics warehouses.
However, on-board weigh scale technology has revolutionized the industry standard for warehousing operations by delivering a more convenient and streamlined weighing solution. Unlike conventional scales, on-board systems are installed on the actual vehicle or piece of equipment, delivering quick and accurate weight measurements more efficiently and fluidly (which is what any logistics or supply chain warehouse can benefit from.)
A Closer Look at On-board Weigh Scales
On-board weigh scales have been in use for several years now and they have had major use in trucks and conveyor belts. This technology has undergone a major revolution across the years and is now more efficient, accurate and simple to use. This has been achieved by the state of the art technology and features that have been put into use in these on-board weigh scales, such as those offered at Walz Scale.
Although on-board scales seem advanced and complex, the science and technology that has been put to use in these weigh scales is quite simple. On-board weigh scales have several features that allow them to perform their job as needed.
One of the components is a load cell. These load cells are similar to the ones found in the platform based weigh scales, only that they can withstand maximum load or above maximum load. The other vital component is a digital display which shows the truck driver or equipment operator the amount of weight or payload he/she has in his/her vehicle or equipment.
The display is assisted by an alarm system which sounds when the set maximum weight is exceeded. Setting of the maximum weight is done via a plug in keypad which is connected to the system. Three points indicating three different weight limits are programmed to the system and the alarm sounds off when the third limit is reached.
To get more technical, the load cells talked about before are technically referred to as the strain gauge load cells. They are placed in between the chassis of the vehicle and the body in a truck and within the conveyor belt system in a conveyor belt.
These strain gauge load cells use the change in electrical resistance to determine the weight on the truck or equipment. They relay very accurate information and have an enhanced longevity. They are very flexible in design as they can be customized for different body set-ups and adjusted for the accommodation of the entire weight of the vehicle or equipment.
From here, the system is wired to the display and in the case of a truck; the ignition switch of the vehicle. This means that any time the vehicle is on, the system is also on. For conveyor belts, microprocessors are included in the design. They monitor the weight in the destination point of the conveyor belt and if the limit is reached, the conveyor belt is shut down automatically.
Advantages of Using On-board Scale Technology
On-board scales come with a number of advantages, which explains their popularity in so many industries. In short, these scales are very cost effective. The common phrase used to explain this cost effectiveness is, "You don’t bring the load to the scale. The scale comes to you."
This implies that unlike platform-based weigh scales (such as pallet scale systems) that required one to arrive with the load to measure weight, on-board weigh scales cut on this transportation cost by offering immediate, real-time weight monitoring. For warehousing and logistics companies, this can offer incredible value.
These scales are also efficient and profitable to a business, whether it is a truck business mining business or an industry relying on conveyor belts and forklifts, as compared to the conventional platform based weigh scales. The data obtained from these scales are also very accurate, thus good enough to be within your equipment or truck.
