High quality load cell sensor
The terminology of load cell specification

Mar 01, 2019

If you want to know more aluminum alloy weighing sensor, you had better to understand some main terms of the specification, which will help to decide which high profile platform load cell fitted into your application for weighing or force measurement.

Accuracy – Normally quoted as either a percentage of full scale output or a percentage of the applied load. The accuracy figure is the combined error caused by non-linearity, repeatability and hysteresis error values in the load cell.

Calibration – The comparison of load cell output against standard test loads.

Rated Capacity – The maximum load over which the load cell will operate within its specifications.

Rated Output – The nominal mV/V output of the load cell.

Combined Error – The maximum deviation of the calibration curve from the straight line drawn between minimum load output and maximum load output, normally expressed in units of %FS. Both ascending and descending curves are considered.

Zero Balance – The output of the load cell at no load, normally quoted as a percentage of full scale. Also known as zero offset.

Creep – The change in load cell signal occurring with time, while under constant load, and with all environmental conditions and other variables remaining constant; usually measured with rated load applied and expressed as a percent of rated output over a specific period of time.

Then you should also know that a weight sensor or force transducer is a physical element that can translate pressure into an electrical signal. There is a strain gauge load cell, which is a mechanical element of which the force is being sensed by the deformation of a (or several) strain gauge(s) on the element.
