Ambient Conditions

The humidity, pressure, temperature, etc surrounding the load cell.

Axial Load

A load applied along the primary axis.


The comparison of load cell outputs against standard test loads.


The maximum axial load a load cell is designed to measure within its specification.

Combined error

The maximum real deviation from the straight line between zero and maximum load. This is expressed as a percentage of the rated output.


The change in output signal which occurs under static load and stable ambient conditions.


The physical positional difference at the loading point between no load and maximum load conditions.

Eccentric Load

Any load applied parallel but not concentric with the primary axis.


The voltage applied to the load cell.

Full Scale

The output at maximum load condition.


The peak difference observed between the signal outputs during a loading and unloading cycle.

Input Resistance

The resistance of the load cell measured at the input terminals while the output terminals are open circuit.

Insulation Resistance

Normally measured at 50v, the DC resistance between the load cell body and bridge circuit.


The weight or force applied to the load cell.

Load Cell

A device which produces an electrical signal proportional to the applied force.


The  maximum deviation of the output curve from the zero-maximum load line, measured on increasing load only.


The signal range produced by the load cell. Where the output is directly proportional to load it is expressed in mV/V.

Output Resistance

The resistance of the load cell measured at the output terminals while the input terminals are open circuit.

Overload Rating, Safe

The maximum load in percent of rated capacity which can be applied with permanently affecting the load cell’s characteristics.

Overload Rating, Ultimate

The maximum load applicable before structural failure.

Primary Axis

The axis along which the load cell is designed to be loaded.

Rated Load

The maximum load permitted to be measured to remain within specification.


The maximum difference between output readings under identical environmental and load conditions.


The ratio of change of electrical output to mechanical input.

Side Load

A load at 90 degrees to the primary axis.

Temperature Compensation range

The range of temperatures over which the load cell is compensated to maintain performance characteristics within specified limits.
