Load-cells with semiconductor strain gauges

 

We produce load-cells according to customer requirements.

  • Our load-cells are suitable for measuring forces, mass, pressure, torque, acceleration
  • Accuracy of load-cells (non-linearity + hysteresis) with semiconductor strain gauges is the guaranteed to ± 0.5% of the nominal range or better
  • Safe overload of our load-cells is to 200% nominal range
  • We can use foil strain gauges from other company in load-cells

Load-cells with steel-foil strain gauges

 
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
