Load Cell Terminology

Each country has its own standard for the performance and quality of load cells.In Japan, there is no standard stipulated uniquely for load cells, although JIS(Load Cell - Test Method JIS B7602) and JMIF (Japan Measuring Instruments Federation) prescribe methods for performance tests.
Meanwhile, the OIML (International Organization of Legal Metrology) sets the international recommendation titled “Metrological Regulation for Load Cells,” with which each member country tries to make their local regulation consistent.The terms described below are commonly used by the OIML and its member countries.

Rated Capacity (RC)
The maximum load that a load cell can measure while meeting its specifications.

Rated Output (RO)
The difference when there is no load and when there is a load of rated capacity. It is generally expressed in output per excitation voltage (mV/V). Alternatively called “Span.”

Safe load limit
The maximum load that can be applied beyond the rated capacity without causing any permanent damage. Expressed as a percentage of rated capacity. 

Compensated temperature range
The temperature range within which the rated output and the zero balance are compensated to meet the specifications.

Temperature effect on zero balance
Drifting of the zero balance caused by changes in the ambient temperature.Expressed as a percentage of rated output.

Temperature effect on rated output
Drifting of the rated output caused by changes in the ambient temperature.

Nonlinearity
The maximum deviation in output from the linear calibration curve linking the zero balance and the rated output, which is measured only when the load increases. Expressed as a percentage of rated output.

Hysteresis error
The maximum difference in output between when the load increases and when the load decreases.

Combined error
The maximum deviation of output from the linear calibration curve linking the zero balance and the rated output, including when the load increases and decreases.

Recommended/maximum excitation voltage
The voltage applied to the input terminals of load cell.

Zero balance
The electrical output when the rated excitation voltage is applied without any load on the cell. Generally expressed as a percentage of rated output.

Input terminal resistance
Measured while the output terminals are open, with no load on the cell.

Output terminal resistance
Measured while the input terminals are open, with no load on the cell.

Insulation resistance
The direct current resistance between the load cell unit and its circuit.

Recommended excitation voltage 5-15V, maximum excitation voltage 15V.
