Types of Compression Load Cells
Choose between high-precision analog and smart digital load cell configurations.
Analog Compression Load Cell
The strain gauges inside the load cell generate a small analog signal (mV/V). The junction box combines the signals from all load cells, and the weighing indicator converts them into the displayed weight.
Digital Compression Load Cell
The analog signal is converted into a digital signal inside the load cell. The processed data is transmitted directly to the digital indicator.
