Question

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?

Answer 1

So repeatability delta will be 1 mm

Step-by-step 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
`100\pm0. 5`%

So it can measure
`100+(100* 0.5)/(100)=100.5`

And
`100-(100* 0.5)/(100)=99.5`

So repeat ability
`\Delta =100.5-99.5=1mm`

So repeatability delta will be 1 mm
