Accuracy and Accuracy Class
Accuracy class is dened as the maximum deviation, and is expressed as a percentage of the sen-
sitivity at nominal load. This includes linearity deviation, hysteresis and repeatability error.
Linearity Deviation
Linearity deviation is the maximum deviation from a straight line drawn between the output values
at zero load and nominal load. Linearity deviation is related to the sensitivity.

Hysteresis
Hysteresis is the maximum difference in the output signal at the same load during a cycle from zero
load to nominal load and back to zero load, related to the sensitivity at nominal load. The hysteresis
of a Pressductor transducer is proportional to the load cycle.
