Glossary
Number of divisions
Number of fractions where the manufacturer certifies tthe linearity of the load cell
Combined Error
The sum of linearity, repeteability and hysteresis.
Creep
The variation in load cell output with time after loading from zero to a constant load.
Eccentric Load
Load applied to a load cell displaced from the normal axis.
Excitation
The voltage used to excite the load cell.
Hysteresis
The difference in load cell output at the same load value, between increasing and decreasing load.
Insulation Resistance
Insulation Resistance is the resistance between each cable core (including screen) and local structural earth.
Linearity
The output deviation at intermediate loads from a straight line drawn between zero load and full load outputs.
Overload Limit
Load cells are specified to resists loads beyond rated capacity without permanent zero shift typically up to 150% of rated capacity.
Senses, Six Wire Circuit
An additional pair of wires which are use to mantain a constant supply to the load cells, to remove the errors from long cable lenghts or varying cable temperatures.
Repeatibility
The difference in load cell output with successive load cycling to the same load.
Sensitivity mV/V
The output of load cell in milivolts (mV) per volt (V) of excitation at the rated load.
Span Drift
Variation in weight measurement with temperature or time at maximum live load.
Zero Drift
Variation in weight measurement with temperature or time, at zero live load.
