Interface Solutions for Weighing Applications

Interface sensors are used for an extremely wide variety of test and measurement applications. We also supply different technologies and instrumentation for a range of weighing applications, from packaging to waste management. Determining accurate weight is a key data point that manufacturers in all types of industry use cases. Whether they need the information for transporting an object, lifting the object, or just creating a specification sheet, accurate data on weight, accuracy in weight measurements are fundamental for safety and function.

Here is a quick review some of the weighing applications, everything from the food and beverage industry to agriculture and industrial. And it’s important to note, weighing across these different industries doesn’t always involve a simple scale, each object large or small that needs to be weighed has a different method for doing so and different force sensors to get the most accurate data built into machines or used in conjunction with other hardware components.

SNACK WEIGHING AND PACKAGING MACHINE

A snack manufacturing brand wanted to weigh the amount of their snacks that are automatically dispersed into the bags during the packaging process. In this case, they wanted to weigh the potato chips being packaged and ensure the potato chips are at the exact weight needed due to regulatory standards. Interface provided a solution using multiple SPI Platform Scale Load Cells, and installed it to the potato multi-head weigher and packaging machine. The SPI Platform Scale Load cells were installed inside of the mount that attaches the head weigher to the packaging machine. Force results from the potato chips were read by the load cells and sent to the ISG Isolated DIN Rail Mount Signal Conditioner, where the customer is able to control the automated production from their command center. Using this solution, the customer was able to determine the weight of the potato chips being distributed into their bags with highly accurate results. They  were able to control the automated production process with the provided instrumentation. They will use this same weighing method for other snacks that need to be packaged. Read more here.

WASTE MANAGEMENT CONTAINER WEIGHING

When a waste management company wanted to measure the capacity of their waste containers in order to know when it is time to dispose the waste, Interface proposed a solution using Model WTS 1200 Standard Precision LowProfile™ Wireless Load Cells. The load cells can be installed at the bottom of each waste container leg to measure the sum weight of the container. The data is transmitted to the WTS-BS-4 USB Industrial Base Station with the supplied Log100 software. The customer would then be able to determine when their waste container was at full capacity in order to dispose of the waste, or to transfer it. Read more here.

GARBAGE TRUCK ON-BOARD WEIGHING

A garbage disposal company wanted to test the load capacity of their garbage truck bins so they know when it has reached maximum capacity. Interface’s solution is to customize and install four SSB Sealed Beam Load Cells under the garbage box body, on either side. When trash continues to be piled inside the box body, it will push more force down onto the SSB Sealed Beam Load Cells. When maximum load capacity has been reached, the results can be reviewed and displayed when connected to the 482 Battery Powered Bidirectional Weight Indicator in real time. Using this solution, the customer was able to test the maximum load capacity of the garbage bin attached to the truck, so they know when to empty the truck’s garbage at the transfer station.

MEDICAL BAG WEIGHING

In the medical industry, it is important to monitor the amount of material in a medical bag carrying fluids for an IV. Medical staff also need to know if a medical bag is empty or if the dispensing tubes are blocked. Force measurements can track this. Using Interface Model MB Miniature Beam or MBP Miniature Beam with built-in overload protection combined with Interface instrumentation, force readings can be captured, displayed and stored for this need. Health Professionals can then review and monitor medical bag weights to ensure medicine is properly dispensed and bag is replaced when empty.

Weighing applications are at the foundation of measurement. The earliest force sensors were designed for this purpose, and they continue to be a large part of application testing today. The only difference between now and then is that Interface has nearly perfected their accuracy across different applications with different types of force sensors measuring very large weight and very small, minute forces.

Commercial Food Processing

A food processing plant wanted accurate results of their in-motion check weigher when food is weighed and processed while moving down the belt.  A check weigher is an automated machine for checking the weight of packaged commodities. This included ensuring production line efficiency and food quality, real-time results of their food being weighed, and a load cell that can endure the food industry’s soiled environment.

Interface offered a solution using multiple SPI High-Capacity Platform Scale Load Cells that could be installed in the customer’s equipment that is sued through the production line where product is weighed on the conveyor. The SPI High-Capacity Platform Scale Load Cells delivers precise weighing data. When connected to the 920i Programmable Weight Indicator and Controller, the solution provides the customer real-time results of the weight of the food. The 920i Programmable Weight Indicator and Controller can also read up to four scale channels in real-time. The processing gains in efficiency were visualized and managed during the weighing process to optimize control and production. 

Water Bottle Dispensing and Weighing

A beverage bottle manufacturer wanted to dispense the right amount of fluid into their bottles, and then weigh their bottles to ensure it is at the labeled weight on their product packaging. This is both to minimize waste, but also to meet the standard requirements noted on the packaging. Interface suggested using the MBP Miniature Beam Load Cell, and attaching it under a plate or platform the water bottle is placed on while it is being filled with fluids. The force weight is measured by the MBP Miniature Beam Load Cell, and connected to the 9870 High-Speed High-Performance TEDS Ready Indicator where results are captured, displayed, and recorded by the customer utilizing their water bottle assembly machinery. With this solution, the water bottle manufacturer received highly accurate results of each water bottle being weighed in real-time, using the accuracy to reduce waste and speed processing time.
