Sensor Static

ShenZhen OSENON Technology Co.,Ltd | Updated: Aug 27, 2015

Static characteristics of the sensor means between the static input signal, the output of the sensor and the input is a correlation. Since then both input and output and time-independent, so the relationship between them, namely the static characteristics of the sensor can be used without a time variable algebraic equations, or to enter the amount as abscissa, the amount for the corresponding output The ordinate of the characteristic curve drawn will be described. The main parameter characterizing the sensor static characteristics are: linearity, agility, hysteresis, repeatability, drift. (1) Linearity: refers to the degree of actual versus sensor output and input amount of deviation between the fitted line. It is defined as the actual characteristic curve and fitting than the maximum deviation from a straight line and full-scale output value in the whole range. (2) Agility: Agility is an important indicator of the sensor static characteristics. It is defined as the amount of the increment of the corresponding input than output increment increment and cause. S for agility. (3) Hysteresis: Sensor input from small to large (positive stroke) and enter the amount of descending (reverse stroke) during the change of the input and output characteristic curve does not coincide with the phenomenon become sluggish. Uniform size of the input signal, the output signal of the positive and negative travel sensor size is not equal to the difference between this difference is called hysteresis. (4) Repeatability: Repeatability is the level sensor is input according to a unified direction for the full-scale continuous many changes, the resulting characteristic curve inconsistent.
