We also produce load-cells with steel-foil strain gauges, which we buy from the world manufacturers.
Compared with load-cell with semiconductor strain gauges, load-cell with steel-foil strain gauges have:
- lower output signal (sensitivity up to 4 mV/V)
- lower temperature coeficient of deformation sensitivity
- lower combined error ( hysteresis and nonlinearity)
- lower safe overload
- temperature self-compensation
