Converting scales into intelligent, high-precision systems

For centuries, scales have been indispensable tools for weighing. While early mechanical scales were limited to basic measurements, the introduction of modern force sensors, particularly load cells, has revolutionized this field. Today, Scales No longer just for weighing. They use sensor technologies for smarter automation systems, process control, and data analytics in countless industries.

The load cell is a 20th-century invention, whose decisive breakthrough came in the 1940s with the perfection of the bonded strain gauge. This technology enables the precise and consistent measurement of the smallest deformations in solid materials, which directly correspond to the applied force. Today, this technology enables the measurement of forces ranging from milligrams to millions of pounds.

Load cells enable scales to continuously monitor weight on conveyor belts , track inventory in smart warehouses , and ensure precise dosing in manufacturing, making them indispensable for modern businesses. Interface's expertise in strain gauge load cell technologies across various capacities and sizes supports these advancements. Our precision load cells and integrated solutions are at the heart of this transformation, providing the accuracy, reliability, and flexibility required for today's advanced weighing applications.

As detailed in our new case study “ Smart scales use high-precision sensor technologies ”, the future of weighing systems lies in intelligent, accurate and easily integrated measurement solutions that offer consistent performance and can be adapted to the requirements of virtually any industry.

Interface solutions for applications of different sizes

Interface offers force measurement solutions for scales that meet the demanding requirements of various industries, from measuring minute forces to weighing massive assemblies. Our sensors and measuring devices are used in a wide variety of scale and weighing applications , including:

• Truck and transport scales for weighing heavy vehicles and their cargo use load cells for maximum accuracy.
• Table, floor, and pallet scales use sensor technologies to optimize warehousing and logistics for inventory and shipping controls.
• Automated inventory systems for continuous, real-time inventory tracking use load cells in innovative systems.
• Point-of-sale (PoS) scales are becoming increasingly popular in retail automation for weighing products.
• Tank and hopper scales often use load cells to monitor the weight of materials in large containers.
• Conveyor belt scales and checkweighers require load cell technologies for accuracy in continuous weighing during motion.
• Crane and hanging scales use sensors in load pins and shackles to ensure safe weighing of hanging loads.
• Ingredient and dosing scales require load cells for precise measurements in critical pharmaceutical and food manufacturing.
• On-board vehicle scales use strain gauge sensors to track vehicle load in real time.
• Agricultural and livestock scales require accurate measurements for managing crop yields and animal health.

These applications demonstrate how Interface solutions improve efficiency and safety while providing valuable insights for innovation in manufacturing, logistics, and many other areas. These are just a few examples of how Interface's measurement solutions are used in scales.

Portable scales for vehicle inspection

Overloaded trucks increase the risk of accidents due to impaired braking and handling, and contribute to excessive wear and tear on roads and bridges. Officers need a mobile, reliable, and accurate solution to perform on-the-spot weight checks during routine traffic stops. Interface's WWWP wireless wheel weighing platform offers a portable and highly accurate solution for roadside weight checks. The WWWP displays weighing results directly on the platform or can wirelessly transmit results to the optional remote touchscreen indicator. Read more: Roadside vehicle weight safety checks

Mining tank scales

In mining, precise weighing is crucial for quality control. Monitoring the weight of materials during extraction, storage, and blending is essential. Interface recommends using our WSSCLC-mount load cells in combination with the programmable weight indicator and controller 1280. This system accurately measures the quantity of material added or removed, ensuring process integrity. Read more: Weighing Mining Tanks

Agricultural scales

Farms need to accurately weigh crop yields and livestock. Scales help determine the optimal time for breeding and provide essential data for harvesting, loading, and transport. Interface's solution involves mounting four Sealed Beam Load Cells (SSBs) to the underside of a metal platform. The sensors connect to a JB104SS junction box, which is then connected to a bidirectional 480-degree weight indicator , providing accurate weight readings for agricultural production.

Intelligent pallet scales

Attaching scales to pallets allows for weighing and tracking inventory and shipments. It can also indicate whether products have been removed and even assist in setting weight-based prices. A smart pallet solution utilizes multiple SSB sealed-beam load cells mounted at the corners of the pallet's underside. When connected to wireless WTS-AM-1E strain gauge measurement modules, force data is transmitted wirelessly to a PC, enabling real-time tracking of heavy loads.
