Question

Calculate design-stage uncertainty of the following force sensor.

Resolution 2N, Range: 0~100N, Linearity error 1N, Hysteresis error 1N, Offset error 1N, Thermal stability error 1N, Sensitivity error 2N.

Answer 1

Answer:

Given that

Resolution = 2N

Range = 0 - 100 N

Linearity error = 1N (e_L)

Hysteresis error = 1N (e_n)

Offset error =1N (e_o)

Thermal stability error = 1N (e_T)

Sensitivity error =2N. (e_s)

We know that:

Design uncertainity analysis,

= Interpolation error

= Instrument error
