Types of Cup & Ball Load Cells
Choose between robust analog and precision digital double-ended load cells.
Analog Load Cell
The analog load cell produces a very small millivolt (mV/V) signal proportional to the applied load.
Digital Load Cell
The strain gauges generate an analog signal proportional to the applied load same as analog loadcell. An Analog-to-Digital (A/D) converter converts it into digital data. A microprocessor processes and transmits the digital value to the indicator.
