Loadstar’s breakthrough comes from its use of capacitive technology for load sensing. Unlike conventional resistive load cells based on either strain gauges or piezo-resistive techniques, Loadstar’s patented technology harnesses changes in capacitance to measure loads quickly and accurately.

The sensor accepts a 5V DC input signal and outputs an analog 0.5V – 4.5V DC signal proportional to the applied load. The full scale output range is 4000 mV — two hundred times that of traditional strain-gauge-based load cells. This signal can easily be measured using commonly available Digital Multi-meters. Loadstar provides a calibration chart of load vs voltage.

If you're looking for digital output, check out our digital load cells. Users seeking a frequency based output should review our miniature load cell only 1.25 inches in diameter.

If you use our hybrid adapter board HX-100, you can obtain digital USB output as well as analog 0.5-4.5V DC signal simultaneously.
