Technical term for load cell（Part 3）

Technical term for load cell（Part 3）

①   Load Cell

A device which produces an output signal proportional to the applied weight or force.

②   Natural Frequency

The frequency of free oscillations under no--load load conditions.

③   Nonlinearity

The maximum deviation of the calibration curve from a straight line drawn between the no--load and rated outputs; expressed as a percentage of the rated output and measured on increasing load only.

④   Output

The signal (voltage, current, pressure, etc.) produced by the load cell. Where the output is directly proportional to excitation, the signal must be expressed in terms of volts per volt, per ampere, etc., of excitation.

⑤   Output, Rated

The algebraic difference between the outputs at no--load an at rated load.

⑥   Overload Rating, Safe

The maximum load in percent of rated capacity which can be applied without producing a permanent shift in performance characteristics behond those specified.

⑦   Overload rating, Ultimate

The maximum load in percent of rated capacity which can be applied without producing a structural failure.

⑧   Primary Axis

The axis along which the load cell is designed to be loaded; normally its geometric centerline.

⑨   Rated Capacity (Rated Load)

The maximum axial load the load cell is designed to measure within its specifications.

⑩   Reference Standard

A force measuring device whose characteristics are precisely known in relation to a primary standard.
