A displacement sensor can detect movements of 0 to 100 mm with a repeatability error of 0.5 % and a voltage output of 0 to 10 mV. What is the repeatability Δ in mm rounded to 1 decimal place?

Respuesta :

Answer:

So repeatability delta will be 1 mm  

Explanation:

We have given that displacement sensor detect the movement of 0 to 100 mm

We have given that there is error of 0.5 %

So sensor can measure [tex]100\pm0. 5[/tex]%

So it can measure [tex]100+\frac{100\times 0.5}{100}=100.5[/tex]

And [tex]100-\frac{100\times 0.5}{100}=99.5[/tex]

So repeat ability [tex]\Delta =100.5-99.5=1mm[/tex]

So repeatability delta will be 1 mm
