Driven by continuous advancements in Internet of Things (IoT), microprocessor, and digital load cell sensor technologies, coupled with society’s increasing demand for improved living standards, the retail sector has entered a new phase marked by automation. Among the emerging technologies, intelligent vending systems—particularly those utilizing gravity-based sensing with high-precision load cells—have emerged as key innovations in the market.
Drawing on its extensive experience in weighing load cell development, HAIBOSENSOR Electric Measurement has collaborated with multiple domestic manufacturers of intelligent vending equipment to deliver gravity-sensing modules in various configurations. These modules integrate advanced load cell technology and have undergone rigorous technical validation and production testing to ensure reliability and compatibility. Depending on the design and application requirements of the vending cabinet, the company offers single-point, dual-point, and quad-point load cell solutions. Both analog and digital signal outputs are supported. At the heart of each sensor lies a strain gauge load cell, manufactured using imported materials to guarantee high performance. The sensing units support a wide measurement range from 10 kg to 120 kg, with precision reaching up to 0.02%. Additionally, customized weighing load cell versions are available to meet specific environmental conditions such as temperature variation and long-term load stability. These gravity modules are suitable for intelligent shelving systems in open retail and storage environments.
