Which component of Rockwell Automation allows for weight measurement and feedback?

The Load Cell is specifically designed for weight measurement and provides accurate feedback on the weight of an object. It operates by converting the force of the weight into an electrical signal, which can then be read and interpreted by various automation and control systems. This capability makes load cells essential in applications such as packaging, batching, and industrial weighing processes.

Other components listed do not serve the primary purpose of weight measurement. Conveyors are used primarily for transportation of products and materials rather than measuring weight. Pressure sensors monitor pressure levels and are not intended for weight measurement. Data loggers collect and store data over time but do not directly measure weight; instead, they can log data from various sensors, including load cells, for later analysis. Thus, the primary function of weight measurement is clearly associated with load cells, making it the most appropriate choice in this context.
