Scale indicators interface with load cells through an electrical connection that allows them to measure and display the weight detected by the load cells. Load cells are transducers that convert a force into an electrical signal. When a load is applied, the load cell deforms slightly, and this deformation is measured by strain gauges within the load cell, which change their electrical resistance in response to the deformation. This change in resistance is converted into an electrical signal, typically a small voltage. The scale indicator is designed to interpret this electrical signal. It is connected to the load cell via a cable, which transmits the signal from the load cell to the indicator. The indicator contains an analog-to-digital converter (ADC) that converts the analog voltage signal from the load cell into a digital signal that can be processed by the indicator's microprocessor. The microprocessor in the scale indicator processes the digital signal, applying calibration data and any necessary corrections to convert the signal into a weight reading. This reading is then displayed on the indicator's screen. The indicator may also include features such as tare functions, unit conversion, and data logging, depending on its design and application. In some systems, multiple load cells are used, and their signals are combined by the indicator to provide a total weight reading. The indicator may also include interfaces for connecting to other systems, such as computers or network devices, for data transfer and further processing. Overall, the interface between scale indicators and load cells is crucial for accurate weight measurement, with the indicator serving as the user interface and processing unit for the raw data provided by the load cells.
