Function and difference of weighing module and weighing load cells

In the domain of weighing instruments, weighing modules and weighing load cells constitute two significant components.

A weighing module is a device employed to accommodate the object subject to weighing. It typically comprises components such as a weighing platform, support frame, and protective cover. Its principal function is to support and safeguard the object being weighed and convey the weight information to the weighing load cells.

A weighing load cells, conversely, is a device responsible for converting the gravitational force of the object being weighed into an electrical signal. It employs various principles, such as strain, piezoelectric, electromagnetic, and pressure transmitters, to transform the mass of the object being weighed into an electrical signal output.

Weighing load cells are crucial devices for measuring weight and come in multiple types, including strain gauge, piezoelectric, capacitive, and pressure types. Different types of weighing load cells are applicable to distinct measurement scenarios and precision requirements.

Weighing modules and weighing load cells are typically combined to form an integrated weighing system, utilized for applications like weighing goods, inventory management, and logistics tracking. These systems are extensively applied in various fields such as logistics, warehousing, industry, agriculture, and hospitals.

Although both weighing modules and weighing load cells are utilized for weight measurement, they exhibit certain distinctions in terms of measurement principles and structural forms.

Firstly, in terms of measurement principles, the main role of a weighing module is to support and protect the object being weighed and transfer the force information to the weighing load cells. The weighing load cells, on the other hand, utilizes diverse measurement principles to convert the force information into an electrical signal output. Different types of weighing load cells are suitable for different measurement principles, such as strain gauge, piezoelectric, and capacitive.

Secondly, in terms of structural forms, a weighing module typically encompasses components such as a weighing platform, support frame, and protective cover, which are employed to support the object being weighed and transfer the force information to the weighing load cells. A weighing load cells are composed of multiple components, such as springs, strain gauges, and circuit boards. The load cells can be directly installed on the weighing module or connected to it via a connector for force transmission.

Finally, in terms of application scenarios, weighing modules are primarily utilized for weighing heavy loads and high-weight objects, for instance, trucks, containers, or large machines. Weighing load cells, conversely, are more suitable for applications demanding high precision and accurate measurement, such as laboratories, food and pharmaceutical manufacturing, and other domains.

In conclusion, both weighing modules and weighing load cells are employed for weight measurement, yet their functions differ. The weighing module is accountable for supporting and protecting the object and transferring the weight information to the weighing load cells, while the weighing load cells converts the received information into an electrical signal using different measurement principles and subsequently outputs it to other systems.
