So a 2.96 mV/V load cell will provide 29.6 millivolt signal at full load when excited with 10 volts. ... Input resistance of the load cell's bridge circuit. Measured ...
As the temperature rises the load cell element becomes more elastic and therefore under a constant load will deform more and lead to an increase in output; but the load is still the same. The clever bit in all this is that the resistor in the bridge supply must be a temperature sensitive resistor that is matched to both the material to which ...
The change in material stress deforms the sensor, in which strain gauges are mounted as in a classic load cell. Thus, the weight of the individual wheelset or bogie can be calculated from the specific deformation behaviour of the rail. Advantages: Can be used as a wheel load scale and axle load scale,
The earliest WIM systems, still used in a minority of installations, use an instrumented existing bridge as the weighing platform. [38] [39] Bending plates span a void cut into the pavement and use the flexure as the wheel passes over as a measure of weight. Load cells use strain sensors in the corner supports of a large platform embedded in ...

Figure 2.Greinacher circuit. The Greinacher voltage doubler is a significant improvement over the Villard circuit for a small cost in additional components. The ripple is much reduced, nominally zero under open-circuit load conditions, but when current is being drawn depends on the resistance of the load and the value of the capacitors used.
